Welding Shade Chart: The Complete Guide to Picking the Right Lens Shade (OSHA & ANSI Tables for 2026)

A young helper at a fabrication shop spent a whole afternoon ‘helping’ on a 3/16-inch SMAW job wearing the same #10 helmet his boss used for light sheet metal tacks. By 9 p.m. that night his eyes felt full of sand, he couldn’t stop tearing up, and a nurse told him he’d given himself photokeratitis — essentially a sunburn on his corneas. Nothing about that injury was complicated or unusual. It was one number on a lens he never thought to check.

What the Welding Shade Chart Is (and Why One Number Decades Ago Still Runs Every Shop)

A young helper at a small fabrication shop spent a whole afternoon “helping” on a 3/16-inch stick job wearing the same #10 helmet his boss used for light sheet metal tacks. By nine o’clock that night his eyes felt full of sand, he couldn’t stop tearing up, and a nurse told him he’d given himself photokeratitis — essentially a sunburn on his corneas. Nothing about that injury was complicated. Nothing about it was unusual. It came down to one number on a lens he never thought to check.

That number has a name, a table, and a legal history. It’s called the welding shade chart, and it is still the single most-used safety reference in the welding trades.

What the Chart Actually Is

At its core, a welding shade chart is a simple lookup table. You find your process — stick, MIG, TIG, plasma, oxyfuel cutting, brazing — cross-reference it with your electrode size, arc current, or plate thickness, and read off a minimum protective shade number for your filter lens. That’s it. No software, no subscription, no interpretation degree required.

OSHA publishes two versions of it. The general-industry table in 29 CFR 1910.133(a)(5) keys shade numbers to electrode size and arc current. The construction table E-1 in 29 CFR 1926.102(c)(1) keys shades to electrode diameter and process. Both trace back to the same body of evidence: the NIOSH criteria document on welding, brazing, and thermal cutting hazards, NIOSH Publication No. 88-110.

A Legal Minimum, Not a Target

This is the part people get wrong, so it’s worth stating plainly. The OSHA tables are enforceable minimums. The general standard requires employers to ensure filter lenses have “a shade number appropriate to protect the wearer from injurious light radiation.” The construction standard is even more explicit, saying Table E-1 “shall be used as a guide for the selection of the proper shade numbers” and that “shades more dense than those listed may be used to suit the individual’s needs.”

Translation: you can always go darker. Going lighter without justification is where the citations, and the eye injuries, come from.

Who Uses This Chart

More people than you’d think:

– Welders, every time they swap processes or amp ranges.
– Supervisors and foremen, when writing safe work procedures and job hazard analyses.
– Welding instructors, teaching students why “whatever the boss wears” isn’t a specification.
– Safety officers, during audits and post-incident reviews.

If you’ve landed here wondering whether #10 is enough for your 150-amp MIG settings, or whether brazing really needs a lens at all, you’re exactly who this is written for. The rest of this guide gives you the actual tables in full, in plain English, with real-world scenarios attached.

Why #10 Is the Universal Default

Shade numbers track visible light transmission roughly logarithmically. Each step up blocks meaningfully more light than the last, so the jump from #5 to #10 is enormous, not incremental. Here’s the practical mental model:

A #10 has become the shop default because it comfortably covers most SMAW, GMAW, FCAW, and GTAW work in the 100–250 amp range. It’s dark enough to be safe and light enough to see the puddle. That’s why the kid in our opening story was handed a #10 — and why, for a different job, it was the wrong number.

Before you go further, it’s worth brushing up on the rest of your protective kit: our Welding PPE: The Complete Guide to Protective Gear Every Welder Needs covers everything from helmets to leathers.

What’s Coming Next

Section two explains what the welding arc is actually firing at your eyes. Section three teaches you how to read the chart’s numbers before you use them. Sections four and five hand you the complete arc and gas tables. Sections six through eight cover helmet technology, the nine most common shade mistakes, and what ANSI Z87.1 compliance really means. Section nine closes with a condensed, printable-style summary you can tape to the welder rack.

One number, decades old, still running every shop. Let’s make sure you’re picking the right one.

The Science: What the Welding Arc Actually Fires at Your Eyes

Before we look at a single row of the shade chart, it helps to understand what exactly you are protecting your eyes from. The number stamped on a filter lens is not arbitrary. It is a defense against a specific, well-documented physical hazard: the intense optical radiation produced by an electric arc, a plasma jet, or a fuel-gas flame.

That radiation comes in three bands, and each one attacks your eyes in a different way.

Ultraviolet (UV): The Burn You Don’t Feel Until Later

An electric arc is an extremely efficient ultraviolet source. The UV wavelengths coming off a welding arc fall in roughly the same range as the midday tropical sun, but enormously more intense. Human corneas absorb UV-B radiation almost completely, meaning nearly 100% of the UV-B hitting your eye is deposited in the cornea and the conjunctiva rather than passing through to the retina.

The result is photokeratitis, the condition our helper in the opening story gave himself. The cornea is literally sunburned. Welders call it “arc eye,” “flash burn,” or “welder’s flash,” but the mechanism is identical to a bad sunburn on skin. Here is the cruel part of the injury: it has a delayed onset. Symptoms typically appear 6 to 12 hours after the exposure. That is why so many welders never connect cause and effect. They arc-weld without a hood on a Friday afternoon, feel fine at dinner, and wake up at 3 a.m. with eyes like ground glass, involuntary tearing, and light sensitivity so severe they cannot open their eyes in a lit room.

The damage is temporary in most cases and heals within a day or two, but repeated photokeratitis episodes are not harmless. Cumulative UV exposure to the eye is associated with long-term corneal degeneration and cataract formation. NIOSH documented these optical radiation hazards in depth in NIOSH Publication No. 88-110, “Criteria for a Recommended Standard: Welding, Brazing, and Thermal Cutting”, which remains a foundational reference behind modern filter shade recommendations.

Infrared (IR): The Slow, Cumulative Hazard

Infrared radiation is the “heat” part of the arc’s output, and it is also the part that can pass through the cornea and be absorbed by the lens of your eye. Long-term, chronic IR exposure is associated with cataract formation. The classic analogy is the glassblower’s cataract, sometimes called “glassblower’s catarrh,” observed in workers who stared into molten glass and furnaces for decades. A welding arc delivers the same kind of radiant load, which is why an IR-blocking filter matters even on processes where the visible brightness seems manageable.

Visible Light: Glare, Flash Blindness, and the Retina

The visible band is the part you actually see, and it does real damage too. Intense visible light from an unfiltered arc causes retinal glare and flash blindness: the temporary bleaching of retinal photopigments that leaves you seeing spots and unable to judge distance for several minutes. On a shop floor, three minutes of flash blindness while walking past a cutting station or operating a forklift is its own safety hazard, entirely separate from the eye injury itself.

Both of OSHA’s eye protection standards speak directly to this. 29 CFR 1910.133(a)(1) for general industry and 29 CFR 1926.102(a)(1) for construction both require employers to ensure employees are protected from “potentially injurious light radiation” arising from welding, cutting, or brazing operations. That phrase is the legal hook behind every shade number in every table you will read in this article.

Why Bystanders Are at Risk Too

Here is a fact that surprises most beginners: a welding arc does not become safe with distance in the way a bonfire does. UV output from an arc is strong enough to cause photokeratitis in a helper standing fifteen or twenty feet away, or in the fitter who walks past an open bay without a hood. A #10 lens protects exactly one person: the one wearing it. Anyone in line-of-sight of the arc needs their own protection, which is why welding curtains, screens, and bystander helmets are part of the standard PPE picture laid out in our guide to welding PPE and protective gear.

Why There Is a Whole Chart and Not One Universal Shade

If UV were the only consideration, one very dark lens could cover everything. But hazard levels swing enormously by process and current. A stick electrode running at 60 amps produces a certain amount of UV; a plasma torch cutting at 800 amps produces vastly more, along with a blinding visible spectrum. A 45-amp TIG arc on stainless sits somewhere far below both. The welding shade chart exists because you cannot pick one number and be right for all of them.

So now you know what the arc throws at you: UV that burns the cornea within hours, IR that quietly loads the lens of the eye over years, and visible light that blinds and glares. To pick the right lens against all three, you need the chart.

How to Read a Welding Shade Chart: Shade Numbers, Transmission, and the ‘Too Dark to See’ Rule

Before you trust a single number in the tables ahead, you need to know what a “shade number” actually is. Get this part wrong and the whole chart becomes guesswork — because most welders were never taught how the scale behaves.

What a Shade Number Really Measures

A shade number describes a filter’s optical density — how much light the lens swallows. It is not a linear dial. Each step up removes roughly half to three-quarters more visible light than the step below it, so the scale behaves logarithmically in practice.

Here is the point welders miss: jumping from #5 to #10 is not five small steps. A #10 lens passes a tiny fraction of the light a #5 lens does. “One shade darker” is never a casual change — it is a real reduction in what reaches your eye.

The Trap That Catches Everyone

Filter lenses block ultraviolet and infrared radiation across nearly the entire shade range, from #2 upward. What changes as shade numbers climb is mostly visible light. That single fact explains the most common beginner mistake in every shop: a welder tries a light lens, notices his eyes don’t burn immediately, and concludes the lens is “fine.”

He’s being fooled. The UV is still being stopped — but the sheer glare causes pupil fatigue, flash blindness, and long-term retinal strain. On a bad day, a heat-damaged or poorly manufactured light lens passes enough UV to give him a burn he doesn’t feel until hours later.

OSHA’s Official Rule of Thumb, Verbatim

OSHA doesn’t leave the final adjustment to chance. In 1910.133(a)(5), the agency gives a direct instruction:

“Start with a shade that is too dark to see the weld zone. Then go to a lighter shade which gives sufficient view of the weld zone without going below the minimum.”

Read that carefully. The process always runs in one direction:

1. Begin with a lens darker than you need.
2. Step lighter, one shade at a time, until you can clearly see the puddle and joint.
3. Stop before you drop below the chart’s minimum for your process and current.

The chart minimum is a floor, not a starting suggestion. If the table says #10 for your job, #8 is never an acceptable answer — even if it “looks fine.”

The Sodium-Line Note for Oxyfuel Work

OSHA adds a footnote that matters for gas work: where a torch produces high yellow light, a filter that absorbs the yellow sodium line is desirable. That’s why many gas-welding and cutting lenses carry an amber or green tint instead of plain grey. The tint filters the sodium glare without over-darkening the scene, which is why a #5 gas lens and a #5 arc lens can feel quite different to look through.

Reading the Stamp on the Lens

Every legitimate filter lens and plate must be distinctly marked with the manufacturer’s identity and shade number. OSHA requires this directly — eye and face PPE must be “distinctly marked to facilitate identification of the manufacturer” under 1926.102(a)(4), and protection must meet recognized standards per 1910.133(b)(1), which references ANSI/ISEA Z87.1.

The shade number is usually laser-etched or stamped on the edge of the lens. If it has worn off, faded, or was never there, retire the lens — you are now guessing, and guessing with your eyesight is a bad trade. Check your own stamp before every job rather than trusting the label on the helmet shell. For the full picture, see our welding PPE guide.

Three Practical Scenarios

1/8-inch 7018 rod at 130A. SMAW in this range requires a minimum of #8, though most welders prefer #10 for comfort. Start at #11, step down until the puddle is clear, and never land below the chart minimum. Our E7018 amperage guide covers current settings for this rod.

A helper running 1-inch oxyfuel cutting. This is not arc work, so the requirement drops sharply: oxygen cutting in the 1–6 inch range calls for a minimum of #4. A #10 arc lens would be legal but needlessly dark. A #5 cutting helmet is the right tool.

Hobbyist TIG-welding thin stainless at 45A. GTAW under 50A requires #8. Low-amp TIG is where auto-darkening helmets struggle with sensor sensitivity — if yours won’t darken reliably at 45A, switch to a fixed #8 rather than pushing the sensitivity dial past the manufacturer’s range.

Side Screens and Cracked Shells

One final trap: the lens only protects what sits directly in front of it. Most helmets include side screens with the same filter shade. If yours are missing or cracked, or the shell itself is cracked and light leaks underneath, UV reaches your eyes anyway — often through the gap at the brow or jawline. A perfect #10 lens in a damaged shell is a perfect #10 lens that doesn’t work.

Now that the numbers make sense, the next section hands you the complete arc-welding shade chart, row by row.

The Full Arc Welding Shade Chart: SMAW, MIG, Flux-Core, TIG, Plasma and Air Carbon Arc

This is the table people actually mean when they search for a welding shade chart. OSHA publishes it inside 29 CFR 1910.133(a)(5), the general-industry eye protection rule, and it maps every common arc process to a minimum filter shade. Read it as a floor, not a target.

The OSHA Arc Welding and Cutting Filter Table

Walking the SMAW rows. Tiny rods on tiny current are forgiving: anything under 3/32 in. running below 60A only asks for shade 7. A standard 3/32 or 5/32 rod at 60–160A, which covers the bulk of light fabrication and 3/32 E7018 amperage work, requires shade 8. Step up to 5/32–8/32 in. at 160–250A and the minimum jumps to shade 10. Heavy 5/16 in. and larger electrodes at 250–550A need shade 11. Notice how the shade tracks heat, not habit.

Wire processes are flatter. GMAW and FCAW list shade 7 only below 60A; from 60A all the way to 500A the answer is a flat shade 10. That is why MIG welding safety guidance rarely fusses over amperage once you are past the tacking range. GTAW sits at shade 8 up to 150A, then shade 10 up to 500A, which is plenty for TIG sheet metal settings. Plasma arc welding starts surprisingly light at shade 6 below 20A and climbs to 11 at 400–800A. Air carbon arc cutting sits at 10 for light work and 11 above 500A. Carbon arc welding, the oddball of the group, is pinned at shade 14 for every current.

Construction Table E-1: The Coarser Cousin

Construction work falls under a separate table, 29 CFR 1926.102(c)(1) Table E-1, which keys stick welding to rod diameter only, with no current column:

The two tables genuinely disagree. A 5/32 rod at 90A is shade 8 under the general-industry table but shade 10 under Table E-1. The reason is context: field construction crews handle unknown grounds, out-of-position joints, and helpers who are not always under their own hood, so the older table builds in margin. The 1910.133 table is keyed to actual arc current and is the more precise modern guide in a controlled shop. When both apply, follow the stricter requirement for your situation.

Three Scenarios From a Real Shop Day

Before you buy rods for any of these jobs, it helps to know what electrodes are in welding and how to choose them, since rod diameter and the current it can carry are what drive the shade selection in the first place.

Gas Welding, Oxyfuel Cutting, Brazing and Soldering Shade Chart

Not every hot job runs an electric arc. Oxyfuel welding, cutting, brazing, and soldering make up the other half of the OSHA table, and this is where beginners mess up most often. A 20-pound acetylene torch on 2-inch plate looks intimidating, so people slap on a #10 arc lens. Meanwhile a helper brazing a copper line with a small torch thinks, “it’s just a flame,” and reaches for sunglasses. Both are wrong, just in opposite directions.

The OSHA 1910.133(a)(5) Gas Table

The general-industry table keys gas work to plate thickness rather than amps, because with a flame the heat input and the brightness of the preheat and molten pool scale with how much metal you’re driving. Here’s the full non-arc section as published in OSHA 1910.133(a)(5):

What Construction Table E-1 Says

The construction table, 1926.102(c)(1) Table E-1, publishes ranges instead of single numbers for the same jobs: light cutting “3 or 4,” medium cutting “4 or 5,” heavy cutting “5 or 6,” gas welding light “4 or 5,” medium “5 or 6,” and heavy “6 or 8.” Those ranges exist because flame brightness isn’t fixed. A 3/16-inch preheat tip on thick, cold steel radiates far more visible light than the same joint after it’s warmed up, and a dirty, scale-covered cut throws more glare than clean metal. The higher number in each range is your judgment call for the hottest end of the job.

Why Gas Shades Are So Much Lighter Than Arc Shades

An oxy-acetylene flame burns around 3,100°C, which sounds terrifying, but temperature and ultraviolet output aren’t the same thing. A welding arc produces a plasma with intense UV-B and UV-C in exactly the band that burns corneas. A flame puts out relatively little of that, so the hazard shifts toward visible glare and infrared. That’s why a #4 is perfectly legal for gas welding while the same person would demand a #10 under a stick arc.

Two practical consequences follow:

• Your auto-darkening helmet’s light state may already be dark enough. Most ADFs idle at a #3, #4, or #5 light state. For torch brazing (shade 3), oxygen cutting under 6 inches (shade 3–4), and soldering (shade 2), simply not switching the helmet on, or leaving it in grind mode, often puts you at or near the legal minimum. Wearing a fixed #10 while brazing is over-protection that costs you puddle visibility.
• Squinting still isn’t protection. The chart minimum applies whether the light source is an arc or a flame.

OSHA also notes that where a torch produces high yellow light, a filter that absorbs the sodium line is desirable. That’s the reason gas-welding lenses come in amber, yellow, or deep green tints rather than the neutral grey of arc lenses. If you do a lot of oxyfuel work, a dedicated gas lens is genuinely more comfortable than a gray #5.

One thing the flame table doesn’t change is everything else you wear. Flame-resistant clothing, sleeves, and gloves matter just as much on a cutting torch as under an arc, and the basics are covered in Welding PPE: The Complete Guide to Protective Gear Every Welder Needs (2026).

Note: Torch work also produces carbon monoxide and metal oxide fumes from the heated coating, so ventilation requirements don’t relax just because you switched off the welder.

Bottom line: gas shades look deceptively light, the flame is brighter than beginners expect, and the correct number depends on thickness, not on how brave you feel. Next, we’ll apply all of this to the helmets you actually buy.

Fixed-Shade Glass vs. Auto-Darkening Helmets: Setting Your Shade Correctly on Both

A welding shade chart does nothing until it reaches your eyes, and it reaches them through a helmet. Two technologies dominate: the fixed-shade filter and the auto-darkening helmet. Both keep you compliant with OSHA 1910.133, and both can be set up in ways that quietly defeat the chart.

Fixed-Shade Helmets: Simple, Cheap, and Only as Good as the Lens You Pick

A fixed-shade helmet is a shell, headgear, a filter lens, and a clear cover lens. The filter does all the darkening and never changes. Most are silver-coated polycarbonate or grey-green glass in the classic 2×4¼-inch size. The clear cover is sacrificial, so scratches land on a $2 part instead of a $20 filter.

Picking a shade is a stocking decision as much as a personal one. If your shop runs mostly 1/8-inch stick, buy a stack of #10 filters plus a few #11 for 250-amp-and-up days, and keep a #5 cutting helmet or goggles for oxyfuel work. A common small-shop kit:

• #10 — the default for SMAW, GMAW, FCAW and most GTAW at normal shop currents.
• #11 — heavy stick and anything pushed above 250A.
• #5 cutting helmet — gas cutting, brazing and heating.
• #8 or #9 — low-amp TIG where #10 feels too dark and the chart minimum allows it.
• Clear cover lenses — always in bulk, never missing.

Every filter and frame should carry the manufacturer’s mark. OSHA accepts eye and face protection meeting ANSI/ISEA Z87.1-2010 or earlier ANSI Z87.1 editions under 1910.133(b)(1), so look for “Z87” (“Z87+” for impact) on the shell and the shade number stamped on the filter. If the stamp is gone, retire the lens.

Auto-Darkening Helmets: What the “9–13” Spec Actually Means

An auto-darkening filter (ADF) is a sandwich: a liquid-crystal cell between polarizers, backed by solar cells and a battery, with arc sensors on the front. When the sensors see the arc, a tiny circuit twists the liquid crystals and the lens goes dark in microseconds, then relaxes back a moment after the arc dies.

The spec that matters most is the shade range. Most helmets cover 9–13 or 10–13. Since OSHA calls for shade 10 across most SMAW, GMAW, FCAW and GTAW work in the 160–250A band (see 1910.133(a)(5)), a 9–13 helmet covers nearly everything a general fab shop does. Heavy stick above 250A needs a range that reaches 13, or a dedicated 11–14 model. Digital helmets with 5–13 ranges earn their price for one reason: the #5 setting makes the same helmet legal for light cutting and brazing, so you carry one helmet instead of two.

Sensitivity, Delay, and Grind Mode: The Three Knobs That Get Ignored

Sensitivity sets how bright the arc must be before the lens darkens. Set it too sensitive and the grinder beside you or a neighbor’s tack flashes the helmet shut; set it too dull and a low-amp TIG arc never triggers it at all. Dial it in the actual work area, not the break room.

Delay controls how long the lens stays dark after the arc stops. Short delay suits tack-heavy MIG work where you constantly reposition and want to see instantly. Longer delay protects you from a still-glowing puddle on out-of-position and heavy root passes.

Grind mode locks the lens into its light state, typically #3 or #4. That is legal for grinding and inspection, and not legal for welding. Plenty of welders grind for an hour, snap the helmet down, and weld on a light state. Get in the habit of resetting the dial after grinding; our MIG welding safety precautions guide covers the same discipline for other shop tasks.

Reaction Time Cannot Save a Wrong Shade

Modern helmets advertise reaction times around 1/25,000 second or faster, faster than the human blink reflex. But speed addresses a timing failure, not an intensity failure. A helmet that darkens in 1/25,000 of a second at shade 8 still passes shade-8 light through your cornea on a job that required shade 10. Speed is a comfort feature. The shade number is the safety feature.

That is also why bargain helmets with no Z87 marking and no stamped shade are a bad trade. A cheap ADF with a dead battery is a fixed light-state lens, and a sensor blocked by tape or grime is the same thing. Work on jobsites? Check OSHA construction standard 1926.102, and verify the Z87 mark and manufacturer shade stamp before anyone straps one on.

Recommended Settings Checklist

The helmet is just the delivery system. Whether you spend $30 on a fixed-shade lens or $400 on a digital ADF, the chart still decides the number. For what else belongs on your head and hands, see our welding PPE guide, and pair it with our MIG welder setup guide.

The 9 Most Common Welding Shade Mistakes (and How to Fix Each One)

The chart only helps if the lens on your face matches it. In real shops, it usually doesn’t. These are the nine errors that show up most often in shade-related injury reports and quality callbacks, each with a fix you can apply today.

1. “The Arc Doesn’t Bother Me”

Feeling fine is not a measurement. Retinal and corneal damage from OSHA 1910.133(a)(5) accumulates silently over months or years. The minimum protective shade in the table is a floor, not a suggestion, and the standard’s own rule of thumb forbids dropping below it no matter how comfortable the arc feels.

2. Going Too Dark to See the Puddle

An over-dark lens produces slow travel speed, lack of fusion, and undercut. Worse, it trains the dreaded “head-peeking” habit: the welder tilts the helmet, exposes one eye to the live arc, and finishes the pass half-blind. Unilateral arc eye almost always starts this way. If you can’t see, go one shade lighter, but never under the chart minimum.

3. Using a #5 Cutting Lens for Stick Welding

#5 is a gas-work lens. Shielded metal arc welding at even modest amperage blows far past it. Reserve #5 for the cutting station and keep the stick station stocked with the correct electrode and the matching filter.

4. A Scratched, Warped, or Heat-Checked Filter

A lens that has sat near a preheat flame or been dropped on concrete can craze and distort. You refocus, squint, and get headaches. Retire it.

5. Missing or Torn Clear Cover Lens

The cover lens is sacrificial. All scratches should live there, not on the expensive filter underneath. A missing cover turns a $2 part into a ruined ADF cartridge.

6. Ignoring the Amp Bump

The same helmet, a different job. Bumping from 90A sheet work to 200A structural with 5/32 E7018 changes the required shade. Recheck the chart whenever the current changes.

7. Leaving Helpers and Bystanders Uncovered

Arc UV travels. The fitter holding the fit-up, the grinder operator two bays over, and the apprentice watching from six feet away all need eye protection. A helmet lens protects only the person wearing it. The same logic is covered in our MIG welding safety precautions guide.

8. Ignoring the Manufacturer’s Markings

OSHA 1910.133(a)(4) requires PPE to be distinctly marked. A lens whose shade stamp has faded to nothing is, by definition, unfit for service. Throw it out.

9. Assuming Auto-Darkening Is Always Correct

A dead battery, tape over a sensor, or a knocked dial means a fixed light state, a fixed dark state, or no darkening at all. Test your helmet before every shift. This applies to any ADF, including machines like a MIG/TIG combo welder where the process changes mid-job.

Shade Troubleshooting at a Glance

Cost math: a five-pack of replacement cover lenses costs a few dollars. One shift lost to photokeratitis costs far more. Buy the spares, and for the wider gear picture see our welding PPE guide.

The task: rewrite the fragment to fit between 640 and 960 words, keeping same heading, same facts, all links. Let me count the current fragment’s words roughly.

Let me count. Actually, the instruction says output only the HTML fragment. No tools. Let me just carefully rewrite.

Let me count the current fragment approximate words:

Para 1 (intro): ~95 words.

“Knowing the right shade number is the single most important thing you can do for your eyes. It is also, on its own, nowhere near enough. A welder wearing a perfect #10 lens with bare forearms, no respirator, and a helper standing three feet away in a t-shirt is fully protected on paper and fully exposed in practice. This section is about closing that gap: what regulators actually cite, what the markings on your gear mean, and which hazards a shade chart will never touch.” ≈ 88 words.

Section “Where Shade-Table Citations Actually Land”: para 1 ~95 words, para 2 ~95 words.
Section “What the Z87 Marking Really Certifies”: intro ~45, list ~70, callout ~55, PPE link ~30.
Section “The Hazard the Chart Cannot See”: ~50 + table + ~25 + ~105 + ~45 + ~75.
Section “Skin, Ears…” ~110 + callout ~80 + closing ~55.

Total maybe ~1000-1100 words. So likely too long — need to trim to under 960. Hmm, I’m not sure. Let me actually count more carefully by writing it out… That’s effortful but let’s try approximating. Actually maybe it’s around 1050. Target 640-960, aim ~870-930.

Also note there’s a bug: `` stray at the end of the h3 for “Skin, Ears, and Everything Else UV Touches” — should be fixed.

Compliance, ANSI Z87.1, and What Comes After the Lens: Helmets Are Only Part of the PPE Picture

Getting the shade number right is the single best thing you can do for your eyes. It is also, by itself, nowhere near enough. A welder in a perfect #10 lens with bare forearms, no respirator, and a helper three feet away in a t-shirt is fully protected on paper and fully exposed in practice. This section covers what regulators actually cite, what the markings on your gear certify, and which hazards a shade chart will never touch.

(About 78 words)

Where Shade-Table Citations Actually Land

US welding eye-protection enforcement runs through two standards: general industry under 29 CFR 1910.133 and construction under 29 CFR 1926.102. Neither one just hands you a table. Both put the duty on the employer in two directions: supply equipment with the correct filter shade for the specific operation, and make sure it is worn. A shop that owns the right lenses but lets welders flip their hoods up to tack is as far out of compliance as one that stocks only #10s.

(~88 words)

One clause in both standards is easy to miss: eye and face protection must be distinctly marked to facilitate identification of the manufacturer, per 1910.133(a)(4) and 1926.102(a)(4). In practice, an inspector picking up a helmet or a pair of safety glasses looks for that stamp. Scratched off, faded past reading, or never there, the item fails on identification alone before anyone debates shade 9 versus 10.

(~68 words)

What the Z87 Marking Really Certifies

That stamp, “Z87” or “Z87+,” refers to the ANSI/ISEA Z87.1 standard for occupational and educational eye and face protection. Note: I should link ANSI/ISEA Z87.1? The brief says external sources provided, but here only OSHA/NIOSH links given. Fine, no link for Z87.1; keep text.

The marking means the product passed a defined test set, not a feel-good inspection:

• Impact — non-rated eyewear is tested for basic coverage and optical quality; “Z87+” means the lens and frame passed high-velocity impact testing.
• Optical clarity and filtration — the lens must filter harmful radiation without distorting vision, which is why a scratched or heat-crazed filter is functionally dead even if the tint still looks dark.
• Coverage — the design must shield the eyes from the front and, on goggles and helmets, the sides.

The Hazard the Chart Cannot See: Welding Fumes

A filter lens blocks light radiation. It does not block what you breathe. describes welding fumes as a mix of metals, and most contain a small percentage of manganese — the ingredient that worries occupational health researchers most, because manganese attacks the nervous system.

Those manganese limits are tracked by NIOSH’s pocket guide entry and OSHA’s chemical data. The gap between a 5 mg/m³ ceiling and a 0.02 mg/m³ TLV is not a typo; it reflects real scientific disagreement about how much manganese is safe across a 30-year career. The unsettling part: NIOSH cites studies showing welders exposed to very low manganese — below 0.2 mg/m³ — scoring worse on tests of brain function, motor skills, mood, short-term memory, reaction time, and hand-eye coordination. Long-term overexposure can progress to manganism, a Parkinson’s-like condition with tremor, rigidity, and gait problems.

~100

Metals are not the only hazard. NIOSH researchers identified welder’s anthrax, a rare but serious disease in metalworkers caused by Bacillus anthracis infecting skin or lungs through hot, contaminated metalworking fluid and fume exposure. Rare is not the same as theoretical.

~48

The practical response is ventilation first, respiratory protection second. Local exhaust, good shop airflow, and a fit-tested respirator sized to your exposure are the controls that matter. OSHA’s welding, cutting, and brazing topic page and NIOSH Publication 88-110 are the authoritative starting points, and our companion piece on MIG welding safety precautions and fume control walks through respirator selection and capture-at-the-source.

Skin, Ears, and Everything Else UV Touches

Arc UV burns a cornea in about six hours; run the same arithmetic on exposed forearm skin. Arc exposure produces genuine UV erythema, a welder’s version of sunburn, and repeated exposure is linked to long-term skin damage. The fix is unglamorous: flame-resistant jackets and sleeves, no bare skin, and no rolled-up synthetic cuffs that melt instead of burning. Our what does a welder wear guide covers the clothing side in detail. Add hearing protection too — grinding and flux-core work routinely exceed 90 dBA, and the weld burns on arms pattern we see most often traces straight back to skipped sleeves and rolled cuffs.

Total rough: 78+88+68+85+55+25+45+ (table small) +100+48+72+110+80+50 = ~904 plus table words (~30) = ~935. Plus headings. Hmm word count typically includes headings. Should be near 940ish — risky. Let me trim slightly to be safe, target ~890.

Wait, but I need to double check: is current fragment longer than 960? My estimate was ~1050 but the rewrite at 935 is only slightly shorter. Hmm. Let me actually count the original more carefully to see. Maybe I’m overestimating and it’s actually fine at ~950. But instructions say rewrite to fit — implies it’s off target (either too long or too short). Given the count I did, likely ~1000+. I should aim to get safely within, e.g., 850-920.

Let me trim some by tightening. I’ll produce a final version and count carefully.

Let me write final and count with precision. I’ll count each paragraph.

Hmm, I need bigger cuts. New total after small trims: 945 – 7 – 3 – 5 – 2 – 1 = 927. Still under 960 but let’s get closer to ~900 for safety margin against my counting error (±5%). Actually my counting could be off upward or downward. To be safe, aim for ~890.

Additional cuts:
– P2 (1910.133 para) 79 → trim: “US welding eye-protection enforcement runs through two standards: general industry under 29 CFR 1910.133, construction under 29 CFR 1926.102. Neither one just hands you a table. Both put the duty on the employer twice over: supply the correct filter shade for the operation, and make sure it gets worn. A shop that owns the right lenses but lets welders flip their hoods up to tack is as far out of compliance as one that stocks only #10s.” Saves ~5. Eh.

– P3 67 → fine.
– P6 44 → fine.
– P8 93 → trim: “Those are manganese limits, tracked by NIOSH’s pocket guide entry and OSHA’s chemical data. The spread between a 5 mg/m³ ceiling and a 0.02 mg/m³ TLV is not a typo; it reflects real disagreement about how much manganese is safe over a 30-year career. NIOSH cites studies showing welders exposed to very low manganese — below 0.2 mg/m³ — performing worse on tests of brain function, motor skills, mood, short-term memory, reaction time, and hand-eye coordination. Long-term overexposure can progress to manganism, a Parkinson’s-like condition with tremor, rigidity, and gait problems.”

89. saves 4.

– P9 41 → keep.
– List items 72 → maybe trim slightly: item 2 “Optical clarity and filtration — the lens must filter harmful radiation without distorting vision; a scratched or heat-crazed filter is functionally dead even if the tint still looks dark.” saves 3 by dropping “which is why”.

– P7 “The exposure limits themselves reveal how unsettled this area is:” 10 → keep.

– Closing 58 → fine.

Total now ~927 – 5 – 4 – 3 = 915. Still a bit high but under 960. Hmm, my counts could be slightly off. Let me just be a bit more aggressive in one or two places to land ~880.

Bigger cut candidate: closing “The lens is the start of the checklist, not the end of it.” keep. P5 (PPE link) 29 words — required for internal link, keep but shorten: “For the bigger picture of how eye protection fits a full gear system, see our guide to welding PPE: the complete guide to protective gear every welder needs.” ~28. no change.

Alternatively cut P11 further: drop “Arc exposure produces genuine UV erythema, a welder’s version of sunburn, and repeated exposure is linked to long-term skin damage.” — no, that’s a fact to keep.

Honestly 915 estimate is fine — within 640-960. My counting is reasonably careful. But risk: if I undercounted, could exceed 960. Let me add a safety trim to bring estimate to ~890-900.

Trim P1 more: “Getting the shade number right is the single best thing you can do for your eyes. It is also, by itself, nowhere near enough. A welder in a perfect #10 lens with bare forearms, no respirator, and a helper three feet away in a t-shirt is protected on paper and exposed in practice.” (48)

“This section covers what regulators actually cite, what the markings on your gear certify, and which hazards a shade chart will never touch.” → “Here’s what regulators actually cite, what your gear’s markings certify, and which hazards a shade chart never touches.” (19) saves 4.

P2 trim “Neither one just hands you a table.” → “Neither just hands you a table.” saves 1.

P10 trim “The practical response is ventilation first, respiratory protection second.” → fine.

OK let’s finalize. Estimated total: 915 – 4 = ~911. Fine.

Actually, one more consideration: word counting tools count HTML? No, they count visible text. Also the table cells count. I included ~20 words for the table. Let me tabulate table text:
Header: Source, Limit, Basis = 3. Rows: “NIOSH REL”, “1 mg/m³”, “TWA (8-hour)” = 5; “NIOSH REL”, “3 mg/m³”, “15-minute STEL” = 5; “OSHA PEL”, “5 mg/m³”, “Ceiling” = 4; “ACGIH TLV”, “0.02 mg/m³”, “Respirable TWA” = 5. Total 22. I said 20, close enough.

So total ≈ 913. Good, within range with ~45 words margin. Acceptable.

Hmm, but “Never exceed the maximum.” 913 estimated. My count error could be ±3%. That’s ±27 words → up to 940. Still under. OK.

Let me also double check I keep all facts:
– Two standards ✓
– Employer duty two directions ✓
– Marking clause ✓
– ANSI/ISEA Z87.1 ✓
– Z87 vs Z87+ ✓
– three test categories ✓
– NIOSH fumes metals manganese nervous system ✓
– Table with 4 limits ✓
– NIOSH below 0.2 mg/m³ deficits list ✓
– manganism ✓
– welder’s anthrax ✓
– ventilation first, respirator second, fit-tested ✓
– OSHA topic page, NIOSH 88-110 ✓
– UV erythema, FR clothing, synthetic cuffs ✓
– 90 dBA ✓
– calls to action internal links ✓

Also fix the stray in the h3.

Now write final HTML. Use proper structure. Internal links without target (as in original). External with target and rel.

Note: in the original, 1910.133 linked twice (once as standard, once as (a)(4)), similarly for 1926.102. Keep both since “all of its links” should be retained. That’s fine.

Also mention the “welding shade chart” keyword naturally maybe. The heading is given. Keep intro mention “shade chart.”

Write output.

Compliance, ANSI Z87.1, and What Comes After the Lens: Helmets Are Only Part of the PPE Picture

Getting the shade number right is the single best thing you can do for your eyes. It is also, by itself, nowhere near enough. A welder in a perfect #10 lens with bare forearms, no respirator, and a helper three feet away in a t-shirt is protected on paper and exposed in practice. Here’s what regulators actually cite, what your gear’s markings certify, and which hazards a shade chart never touches.

Where Shade-Table Citations Actually Land

US welding eye-protection enforcement runs through two standards: general industry under 29 CFR 1910.133 and construction under 29 CFR 1926.102. Neither just hands you a table. Both put the duty on the employer in two directions: supply the correct filter shade for the specific operation, and make sure it gets worn. A shop that owns the right lenses but lets welders flip their hoods up to tack is as far out of compliance as one that stocks only #10s.

One clause in both standards is easy to miss: eye and face protection must be distinctly marked to facilitate identification of the manufacturer, per 1910.133(a)(4) and 1926.102(a)(4). In practice, an inspector who picks up a helmet or a pair of safety glasses looks for that stamp. Scratched off, faded past reading, or never there, the item fails on identification alone before anyone debates shade 9 versus 10.

What the Z87 Marking Really Certifies

That stamp, “Z87” or “Z87+,” refers to the ANSI/ISEA Z87.1 standard for occupational eye and face protection. The marking means the product passed a defined test set, not a feel-good inspection:

• Impact — non-rated eyewear is tested for basic coverage and optical quality; a “Z87+” marking means the lens and frame passed high-velocity impact testing.
• Optical clarity and filtration — the lens must filter harmful radiation without distorting vision; a scratched or heat-crazed filter is functionally dead even if the tint still looks dark.
• Coverage — the design must shield the eyes from the front and, on goggles and helmets, from the sides.

For the bigger picture of how eye protection fits a full gear system, see our guide to welding PPE: the complete guide to protective gear every welder needs.

The Hazard the Chart Cannot See: Welding Fumes

A filter lens blocks light radiation. It does not block what you breathe. NIOSH describes welding fumes as a mix of metals, and most contain a small percentage of manganese — the ingredient that worries occupational health researchers most, because manganese affects the nervous system.

The exposure limits themselves reveal how unsettled this area is:

Those are manganese limits, tracked by NIOSH’s pocket guide entry and OSHA’s chemical data. The spread between a 5 mg/m³ ceiling and a 0.02 mg/m³ TLV is not a typo; it reflects real disagreement about how much manganese is safe over a 30-year career. NIOSH cites studies showing welders exposed to very low manganese — below 0.2 mg/m³ — performing worse on tests of brain function, motor skills, mood, short-term memory, reaction time, and hand-eye coordination. Long-term overexposure can progress to manganism, a Parkinson’s-like condition with tremor, rigidity, and gait problems.

The hazards do not stop at metals. NIOSH researchers identified welder’s anthrax, a rare but serious disease in metalworkers caused by Bacillus anthracis infecting the skin or lungs through hot, contaminated metalworking fluid and fume exposure. Rare does not mean theoretical.

The practical response is ventilation first, respiratory protection second. Local exhaust, good shop airflow, and a fit-tested respirator sized to your exposure are the controls that matter. OSHA’s welding, cutting, and brazing topic page and NIOSH Publication 88-110 are the authoritative starting points; for respirator selection and fume capture at the source, read our guide to MIG welding safety precautions and fume control.

Skin, Ears, and Everything Else UV Touches

Remember what arc UV does to a cornea in six hours; do the same arithmetic on exposed forearm skin. Arc exposure produces genuine UV erythema, a welder’s version of sunburn, and repeated exposure is linked to long-term skin damage. The fix is unglamorous: flame-resistant jackets and sleeves, no bare skin, no rolled-up synthetic cuffs that melt rather than burn. The what does a welder wear guide covers the clothing side in detail. Add hearing protection, too: grinding and flux-core work routinely exceeds 90 dBA, and the weld burns on arms pattern we see most often traces back to skipped sleeves and rolled cuffs.

The lens is the start of the checklist, not the end of it. Get the shade right, then confirm the frame is Z87-marked, the sleeves are on, the respirator is fit-tested, the ventilation is running, and everyone inside UV range is covered. That full system is what keeps a welder welding for thirty years instead of thirty months.

Quick-Reference Shade Chart Summary, Shop Setup Tips, and Final Takeaways

You have made it to the part you can print, tape inside your locker, and glance at every morning. Here is the whole article compressed into one table.

The One-Glance Welding Shade Chart

Build the Shop Around the Chart

Charts only work when they are physically where the work happens. The shops that never see an arc-eye injury treat shade selection as a system, not a personal decision:

• Stock the full ladder. Keep #2, #3, #5, #8, #10, #11, #12 and #14 filters on the shelf so nobody has to improvise.
• Spares at every station. A cover-lens pack next to each hood means a scratched lens gets swapped instead of tolerated.
• Stamp the shade inside every helmet. One number, written large, ends the guessing game when a hood changes hands.
• Laminate the chart in two places: on the welder rack and in the cutting area, where the gas-shade numbers get ignored most often.
• Add shade selection to the pre-job briefing. If the amp setting changes, the lens decision gets revisited out loud.
• Retire unmarked and faded lenses. If you cannot read the stamp, you cannot verify the shade.

A Short Buying Guide Summary

When it is time to buy, match your dominant process to the auto-darkening filter’s adjustable range — a 9–13 ADF handles most arc work but cannot legally do gas welding at shade 4, while a 5–13 digital range is far more versatile. Confirm the Welding PPE: The Complete Guide to Protective Gear Every Welder Needs (2026) checklist before checkout, look for the ANSI Z87 marking on the shell and lens, and budget for genuine replacement cover lenses rather than hoping the originals last. Many fabricators keep a cheap fixed-shade hood dedicated to hot, dirty cutting work so the expensive ADF stays clean. Our MIG Welding Safety Precautions: The Complete Guide to Staying Safe in 2026 walks through the same setup logic for wire-feed stations, and our What Does a Welder Wear? The Complete Welding PPE Guide covers everything below the chin.

Three Rules to Remember

1. The chart minimum is a floor, not a target. OSHA’s own instruction is to start too dark and step lighter — never the other way around.
2. Darker is always legal; lighter is a gamble. Table E-1 says it outright: shades more dense than those listed may be used to suit the individual’s needs.
3. The lens protects only the person wearing it. UV does not respect a helmet edge.

Everything else in this guide — the amp tables, the sensitivity dial, the cover lenses — is just supporting detail for those three ideas.

The Two-Second Decision

That helper with the sandy eyes at nine at night did not lack training, courage, or equipment. He had the right helmet in his hand. He just never checked whether one number on a lens matched the job in front of him. A free chart, two seconds of attention, and a habit his boss could have built into every pre-job briefing would have wiped out the whole miserable evening.

Print the table. Stamp the hoods. Ask the question before you strike the arc. Your eyes do the rest of the work for the next forty years, and they only get one set.

Frequently Asked Questions

What shade lens do I need for 1/8-inch stick welding?

For 1/8-inch SMAW electrodes running in the 160-250A range, OSHA’s general-industry table lists a minimum protective shade of 10. A #10 is the standard choice for most shop stick welding, and going darker to #11 or #12 is always acceptable under OSHA’s guidance.

Is shade 10 or 11 better for welding?

Both meet the OSHA minimum for most common arc welding currents. Shade 10 is the practical default for SMAW, MIG, flux-core, and TIG at typical shop amperage; shade 11 gives extra margin at higher currents or for welders sensitive to glare. Choose the lightest shade that still lets you see the weld zone clearly, never below the chart minimum.

Can I use a shade 5 cutting lens for stick welding?

No. Shade 3-6 lenses are intended for gas welding, oxyfuel cutting, brazing, and soldering, where arc UV output is far lower. Using one for SMAW, MIG, or TIG exposes your eyes to ultraviolet radiation that can cause photokeratitis even if you don’t feel immediate discomfort.

What does ‘start too dark, then go lighter’ actually mean?

It is OSHA’s official rule of thumb printed with the shade table: pick a shade too dark to see the weld zone, then step down one shade at a time until you can see the joint and puddle well — but stop before going below the minimum shade listed for your process. It keeps you legal and gives you the best possible view.

Do auto-darkening helmets need to match the shade chart too?

Yes. An auto-darkening helmet only protects you if it is set to at least the chart minimum for your process and current. Most ADF helmets cover shades 9-13; set the dial to the minimum for your job, and use the grind mode (#3/#4 light state) only for grinding, never for welding.

What shade for gas welding and oxyfuel cutting?

Per OSHA’s table, gas welding is shade 4 for light work under 1/8 inch, 5 for medium, and 6 for heavy over 1/2 inch. Oxygen cutting is shade 3 light (under 1 inch), 4 medium (1-6 inches), and 5 heavy (over 6 inches); torch brazing is 3 and soldering is 2.

Is a darker shade always safer?

Within reason, yes — OSHA explicitly allows shades darker than the table. But too dark a shade makes you peek under the helmet or lose puddle control, creating new safety and quality risks. The goal is the lightest shade that safely lets you see, at or above the tabulated minimum.

Does a proper welding shade protect me from welding fumes?

No. Filters block optical radiation, not particles. Welding fumes are metal aerosols — most contain manganese — and require ventilation and, where exposure limits demand it, respiratory protection. NIOSH lists a 1 mg/m³ TWA REL for manganese, while OSHA’s PEL is a 5 mg/m³ ceiling.

How do I know what shade my lens is?

Shade number and manufacturer are stamped or printed on the edge of the filter lens and on the helmet shell for auto-darkening models. OSHA requires eye and face PPE be distinctly marked; if the marking is worn off or missing, replace the lens rather than guess.
