Welding Sticks: The Complete Guide to Choosing, Using & Mastering SMAW Electrodes

What Are Welding Sticks? A Practical Introduction to SMAW

It’s 6 p.m. Saturday; the farm gate hinge snapped. The only machine in the barn is a dusty buzz-box on an extension cord. You grab welding sticks, wondering which works on rusty steel with low-output AC. Choosing the right stick — and using it right — separates a weld that lasts decades from one that fails fast.

Those rods are the heart of stick welding — the most widely used welding process on earth.

What Exactly Is a Welding Stick?

“Welding stick” is the everyday name for a covered electrode in Shielded Metal Arc Welding (SMAW). You may also hear stick welding, manual metal arc (MMA), or “arc” welding. A consumable metal rod is clamped in an electrode holder; an electric arc jumps from the rod’s tip to the workpiece, melting both into a molten pool that cools to form a solid joint.

Unlike wire-feed processes, everything is in one stick — filler metal and shielding combined. No gas cylinder, spool gun, or wire feeder. That simplicity is why a $150 AC buzz-box can still repair a trailer on the roadside.

The Anatomy of a Stick

Every covered electrode has two parts:

• Core wire — solid metal rod at center; it melts to become filler metal. Its chemistry (mild steel, stainless, cast iron) determines what you can weld.
• Flux coating — mineral jacket around the core. When the arc burns, flux decomposes, creating a shielding gas cloud that blocks air from the molten pool. Leftover flux floats to the surface and solidifies into slag, a glassy crust that protects the cooling weld from the atmosphere.

A Very Short History

Metal arc welding dates to the early 1900s, when inventors found that an uncovered bare metal rod could fuse steel with an electric arc. Those bare rods produced brittle, gassy welds because nothing blocked oxygen and nitrogen. Strohmenger patented a lime-coated electrode, and later extruded flux coatings were developed — breakthroughs that turned arc welding from novelty into industrial backbone. Like MIG’s story reshaping production, this coated rod became the ancestor of every electrode we use today.

Why Stick Still Dominates

Despite competition from MIG and flux-core, stick remains the most-used welding process by materials consumed. According to a US EPA review cited in a CDC/NIOSH welding study, SMAW accounts for roughly 45% of welding in the US by materials consumed, ahead of GMAW/MIG at about 34% and FCAW at roughly 17%. That’s an enormous share for a century-old process.

Stick electrodes run on cheap, portable machines. They tolerate rust, mill scale, and dirty steel better than most processes. They handle outdoor wind, vertical and overhead work, and remote repairs where gas cylinders are impractical. Even where automation like robotic submerged arc welding dominates heavy fabrication, stick remains the field-repair standard.

What This Guide Covers

Over the next nine sections, we’ll go deep. You’ll learn how arc, flux, and slag interact; how to decode AWS codes (E6010, E6011, E7018, and friends); and how to match a rod to your job. We’ll cover amperage, polarity, and settings, then striking and running an arc with control. You’ll get guidance on storing and reconditioning rods, staying safe around fumes and arc flash, and fixing common beginner mistakes. By the end, you’ll know exactly which stick to grab — and why.

How Stick Welding Actually Works: Arc, Flux, Slag, and Filler

Stick welding looks simple from a distance: clamp a rod, scratch it on the metal, watch the sparks fly. Under the hood, though, shielded metal arc welding is a tightly choreographed dance between electricity, heat, chemistry, and the steady hand of the welder. Walk through the sequence once and you stop fighting the process and start controlling it.

Striking the Arc and Melting Metal

Everything begins when the electrode tip touches the workpiece and then lifts a hair. That brief contact creates a short circuit, and as the rod pulls away, the air gap ionizes and the arc snaps into being — a controlled electrical discharge that can exceed 6,000°F (3,600°C) at its core. That heat does two jobs at once: it melts a pool of base metal and melts the electrode tip.

The electrode is consumed as it welds, so you must continuously feed the rod downward to hold a consistent arc length. Hold it too far away and the arc wanders and spatters; crowd it and the rod sticks to the plate. This constant feed-and-adjust rhythm is the skill every stick welder builds through repetition.

Flux, Shielding Gas, and Slag

The flux coating is the quiet hero. As the arc burns, the coating vaporizes and breaks down, releasing a cloud of shielding gas that pushes oxygen and nitrogen away from the molten pool — otherwise those gases cause porosity and brittle welds. The flux also forms molten slag, a glassy layer that floats on top of the weld and protects it while it cools.

Metal transfer happens across the arc in the form of tiny droplets, carried from the electrode into the weld pool. Once solidified, the slag hardens into a crust you chip away with a slag hammer. What’s left underneath is the finished bead. Designers tune coatings for different jobs — cellulosic, rutile, and basic types behave very differently, which is why electrode selection matters later on.

The Electrical Basics: Constant Current and Voltage

Stick welding runs on a constant-current (CC) power supply. The machine holds amperage roughly steady while the welder controls voltage through arc length. That’s unusual: with most welding processes you set voltage and get a self-regulating arc, but with stick, the distance you hold the rod is your heat control. If you want to understand how polarity flips this relationship in other processes, TIG welding polarity makes a useful comparison.

Stick power sources are deliberately “droopers.” Their output voltage falls sharply as current rises, which limits short-circuit current if the rod touches down and helps the arc stabilize. They also carry a relatively high open-circuit voltage (OCV) to strike the arc, but here’s the catch: small AC buzz-boxes may sit around 50V OCV, while many general-purpose electrodes want 70–80V minimum to start and run smoothly. That gap is why a cheap machine sometimes stumbles on certain rods.

Positions and Freeze Rate

Welders work in four positions: flat, horizontal, vertical, and overhead. Flat is easiest because gravity holds the pool in place. Overhead is hardest because the molten metal wants to drip onto you. The key variable is freeze rate — how quickly an electrode’s slag and weld metal solidify. Fast-freezing rods (like E6010 and E6011) set almost instantly, so they hold position in vertical and overhead work without sagging. Slower-freezing rods (like E7018) flow out nicely on flat and horizontal joints but demand more care when you’re upside down.

Freeze rate, arc length, travel speed, and rod angle all interact, and the only real way to internalize them is time under the hood. Structured welding practice turns these variables into muscle memory, and checking manufacturer datasheets for each electrode confirms the exact arc behavior to expect.

Decoding the AWS Electrode Code: E6010, E6011, E6013, E7018 and More

That jumble of numbers stamped on a welding stick isn’t random. It’s a classification defined by the American Welding Society, and once you learn to read it left to right, you can match a rod to a job in seconds. The system is refreshingly logical: every character earns its place, and nothing is decorative.

Reading the Code Letter by Letter

Take E7018 and pull it apart:

• The “E” prefix simply means “electrode” — a stick designed to carry a covered-electrode arc.
• The first two digits give the minimum tensile strength in thousands of psi (ksi). So “70” means 70,000 psi minimum tensile strength.
• The third digit tells you the usable welding position. “1” means all-position, so the rod can be run flat, horizontal, vertical, and overhead.
• The fourth digit is a package deal: it signals the flux coating type and which current/polarity the rod runs on. “8” equals a low-hydrogen, iron-powder flux that runs on AC or DCEP.

Compare that to E6011: “60” is 60,000 psi minimum tensile, “1” is all-position, and “1” is a high-cellulose potassium flux that runs on both AC and DC. Same skeleton, different filler chemistry. Notice that the tensile and position digits stay put; only the last character changes to define a new filler. A “3” in the third position, for example, signals a flat-and-horizontal-only rod, which matters the moment a joint demands out-of-position work. The Miller knowledge hub on common stick electrodes breaks down these coating families in more depth.

The Six Sticks You’ll Actually Use

Penetration, Arc Feel, and Current

Penetration varies wildly across these rods. E6010 and E6011 dig in hard, biting through rust, mill scale, and dirty joints — which is why 6010 remains the go-to for root passes on pipe. That aggressive arc means you must move confidently or risk burn-through on thin metal. E6013 sits at the opposite end: a soft, stable arc with light penetration and a tidy bead that flatters beginners. It also tolerates poor fit-up and runs happily on low open-circuit-voltage machines, which is why so many hobby welders start there.

E7018 bridges the gap between strength and usability. The iron-powder flux boosts deposition, and the low-hydrogen chemistry resists cracking under load, making it the backbone of structural and code work. If you’re dialing one in, our guide to 3/16 E7018 amperage, settings, and technique covers the numbers. For E7024, remember the position limitation: that heavy iron-powder coating is built to pour metal downhill in flat and horizontal fillets, not overhead. Keeping the rod dry matters here too, because a damp low-hydrogen coating can introduce the very hydrogen you’re trying to avoid.

Polarity trips people up, so keep it straight: electrodes ending in 0 are DCEP-only, ending in 1 run on AC or DC, and ending in 3, 4, 6, or 8 typically accept AC or either DC polarity. If DC versus AC still feels muddy, this explanation of DCEN versus DCEP clarifies why electron flow flips penetration and bead shape.

Get comfortable reading that five-character code and you’ll stop guessing. Add regular seat time to build the muscle memory, and our guide to building real welding skills through practice will help you put each electrode to work. The code, after all, is just a promise about how the rod will perform — and reading it confidently is the first step toward choosing the right one every time.

Choosing the Right Welding Stick for the Job

Walk into a welding supply shop and you’ll face a wall of electrodes in dozens of numbers, each claiming to be the best. The truth is simpler: you don’t need most of them. A handful of sticks covers the vast majority of real-world work, and the right one usually falls out of a few questions you can answer before you even strike an arc.

The Electrode Selection Framework

Run every job through these filters:

• Base metal — carbon steel, stainless, cast iron, or hardfacing?
• Thickness — sheet metal, plate, or heavy structural sections?
• Joint design — open root, tight fit-up, or a wide bevel?
• Position — flat and horizontal, or vertical and overhead?
• Power source — AC buzz-box, DC inverter, or engine-driven generator?
• Cleanliness — bright steel, or rust, paint, and grease?
• Code — will an inspector look at this weld?

Answer those seven and the electrode picks itself. Two questions trip people up most. First, position: not every electrode handles vertical and overhead — E7024 is flat-only, while E6010, E6011, E6013, and E7018 run all-position. Second, power: E6010 needs DC, but E6011, E6013, E7018, and E7014 will all run on AC machines, which matters when your only welder is a buzz-box.

E6010 and E6011: Dirty Steel, Open Roots, Deep Penetration

When the steel is rusty, the fit-up is ugly, and the machine is an old AC tombstone, reach for E6011. It throws a forceful, deep-penetrating arc that cuts through mill scale and light contamination, and unlike E6010 — which is DC-only — it runs happily on AC. That combination made E6011 a staple of farm repair and generator-based welding. Choose E6010 on DC for pipe roots and deep penetration where you can control the arc. Both are fast-freeze electrodes that handle vertical and overhead well. Keep the arc tight and travel steadily to get the most from that digging action.

E6013: Sheet Metal, General Repair, Nice Appearance

E6013 is the friendly all-rounder: easy to start, smooth-running, and it lays a tidy bead that cleans up nicely. It’s also forgiving on low-output AC machines. The catch is shallow, limited penetration, which makes it a poor choice for heavy structural work. Use it for sheet metal, light brackets, thin tubing, and cosmetic repairs. If you’re building real welding skills, E6013 is a great stick to learn arc control with.

E7018: Structural Work and Thick Sections

E7018 is the workhorse structural electrode. It’s a low-hydrogen, iron-powder electrode that deposits smooth, ductile, high-strength weld metal. Choose it for thick sections, high-strength steels, and any joint that must resist cracking. The trade-offs: it demands clean, dry storage and a DC+ preference for best results. Get your heat right with our guide to 3/16 E7018 amperage settings.

E7014 and E7024: High Deposition for Flat Work

When you want to pile on metal fast, E7014 (all-position, iron-powder, easy to run) and E7024 (heavy iron-powder coating, very high deposition) come into play. E7024 is a flat and horizontal electrode only — it can’t handle vertical or overhead — but where you can lay it flat it melts metal like a fire hose.

Stainless, Cast Iron, and Hardfacing

Different base metals need different sticks:

• Stainless: Match the grade — 308L for 304/304L, 309L for joining stainless to carbon steel.
• Cast iron: Use nickel-based electrodes (like ENi-Cl) and short, stringer beads with preheat to avoid cracking.
• Hardfacing: Apply a wear-resistant overlay to bucket teeth and plows; check factors like welding hardened steel before you start.

When the Code Decides For You

On structural work, the code often makes the choice for you. Per AWS D1.1, ASTM A36 up to 3/4 inch thick may be welded with non-low-hydrogen electrodes, but thicker sections and higher-strength grades like A992 require low-hydrogen electrodes such as E7018, matched with appropriate preheat. Ignore that and you’re welding a crack waiting to happen. The best electrode is the one matched to the metal, the machine, and the code — not the one with the highest number on the box.

Amperage, Polarity, and Settings: Dialing In Your Stick Welder

Two welders can run the same rod on the same joint and get completely different results. The machine settings are usually the difference. Amperage, polarity, and a handful of stabilizer controls decide whether your arc purrs or sputters, so taking thirty seconds to dial them in before you strike is time well spent.

Amperage: The Setting That Does the Heavy Lifting

Electrode diameter sets the baseline. A fatter rod carries more current and deposits more metal, so match rod size to plate thickness first, then fine-tune within the rod’s range. As a rule, thicker steel wants more amps and a larger rod; thin sheet wants fewer amps and a smaller one.

Those are starting points, not gospel. The exact number shifts with the electrode type: a 1/8-inch E7018 typically runs about 110–140 A on thicker plate, while a 3/32-inch E6013 is happy around 40–80 A. If you want a deep dive on the low-hydrogen side, see our guide to 3/16 E7018 amperage.

Reading the arc tells you if you’re off. If the rod stubs out, sticks to the plate, or feels lazy with poor fusion, you’re running too cold — bump the amps up. Excessive spatter, burn-through on thin metal, and undercut along the toes mean you’re too hot. Nudge it down in 5-amp steps.

Polarity: Which Cable Carries the Heat

Polarity is about which cable carries the heat. In DCEP (electrode positive), roughly two-thirds of the heat lands in the work, giving deep penetration. In DCEN (electrode negative), the heat shifts to the electrode, producing a shallower, faster-freezing weld. AC splits the difference and helps blast through rust and mill scale.

Not every rod plays nice with every polarity. E6010 is DCEP-only. E6011 and E6013 run on AC or DC, which makes them forgiving on buzz-boxes. E7018 runs on AC or DCEP. Getting this wrong turns a good rod into a sputtering mess. For cross-process context, our polarity for flux core welding article shows how the same DCEP/DCEN logic shapes wire welding.

• E6010: DCEP only.
• E6011: AC or DC, either polarity.
• E6013: AC or DC, the friendliest on cheap AC buzz-boxes.
• E7018: AC or DCEP.

On an AC-only machine you’re locked into AC, so E6011, E6013, and AC-rated E7018 are your bread and butter. A DC machine adds DCEP and DCEN, and with them a wider menu. Those same polarity principles carry into other arcs, and our TIG welding polarity guide breaks down DCEN, DCEP, and AC for precision work.

Duty Cycle, Hot Start, and Arc Force

Duty cycle is how long a machine can run at a given amperage before it needs to cool, expressed as a percentage over a ten-minute window. A 60% duty cycle at 150 A means six minutes of welding and four minutes of rest. Running past it overheats the machine and shortens its life.

Two knobs smooth out the arc. Hot start gives a brief amperage boost at the instant you strike, preventing the rod from sticking. Arc force (sometimes called dig) adds current when the arc length shortens, keeping the puddle from freezing when you push into a tight root. Start both mid-range and adjust from there.

Every number here is a starting point. Weld a test bead on scrap of the same thickness before you commit to the real part, watch the puddle, and tune from there. Building that instinct is exactly what our guide to welding practice is about.

Stick Welding Technique: Striking, Running, and Controlling the Arc

Good stick welding looks effortless. It isn’t. Every decent bead comes down to four things you control constantly: how you start the arc, how far the rod sits off the metal, how you angle it, and how you read the puddle. Get them wrong and you’ll fight spatter, slag inclusions, and cold lap all day.

Striking the Arc: Tap vs. Scratch

Two reliable ways to start. A scratch start is the gentler option: drag the rod tip across the surface like striking a match, then lift to arc length once it lights. It suits easier-running rods and clean steel. A tap start — sometimes called a peck start — touches the rod down and snaps it straight back up. Use it with E6010 and E6011, whose cellulosic coating wants a firm, quick strike and gives a fast-freezing, forceful arc ideal for vertical-up and root passes.

Whichever you use, don’t stick the rod. Rest too long and the current fuses the tip. Twist it free fast or it’ll overheat and the flux will crack off.

Arc Length: The Distance That Makes or Breaks the Bead

Keep arc length roughly equal to the electrode’s core diameter — a 1/8-inch rod wants about 1/8 inch of gap. Too long and the arc wanders, spatter flies, and porosity creeps in as it sucks air. Too short and you stub and lose visibility as flux crowds the puddle. Listen for a crisp, steady crackle like bacon frying; a hollow hiss or popping stutter means your length is off.

Travel Angle, Speed, and Rod Manipulation

Stick welding normally uses a drag (backhand) angle — the rod tilted 10 to 15 degrees from vertical, leaning in the direction of travel. Pushing the puddle is unusual with SMAW and tends to shove slag ahead of the arc. Travel fast enough to keep the puddle two to three times the rod diameter wide. Too slow and you build a fat, cold bead; too fast and the toes don’t tie in.

For manipulation you have two fundamentals. A stringer bead is a straight, narrow pass with little side-to-side motion — strong, simple, and the backbone of most structural work. A weave moves the rod across the joint in a controlled pattern (zigzag, C, or figure-eight) to fill wider gaps and control heat. Weaves are handy flat and horizontal but get you in trouble overhead.

Position-by-Position Guidance

• Flat: The easiest position. Hold a slight drag angle and let the puddle flow. Weaves are fine here.
• Horizontal: Watch the top toe — gravity pulls the puddle down, so pause at the upper edge to prevent undercut and sag.
• Vertical-up: The go-to for strength. Use a tight arc, short stringers or a slight weave, and let the fast-freezing puddle set before you climb. Cellulosic rods shine here.
• Vertical-down: Fast and shallow. Only suits certain electrodes like E6013 — never low-hydrogen rods, which need vertical-up. Best for thin sheet where heat must stay low.
• Overhead: Turn the heat down, keep the arc short, use small stringers, and resist weaving. Let the forceful arc push metal into the joint.

Reading the Puddle and the Slag

Your eyes should live on the puddle, not the arc. Watch both toes — the outer edges — and confirm they’re wetting into the base metal rather than sitting on top. Slag tells the rest: it should flow smoothly behind the puddle. If it rolls ahead of the arc, you’re dragging too slow or too low; if it’s thick, chunky, and hard to chip, your arc ran long or too cold. Peeling long ribbons off a clean bead is the sign you got it right.

Practice Drills That Actually Build Skill

Pad beads are the classic starting point: lay overlapping stringers across a flat plate until each row is even, then practice restarting mid-bead. Next, run vertical-up stringers on scrap, then horizontal T-joints. Finally, drill your starts — 20 tap starts in a row until the arc lights without sticking. Follow a real welding practice guide to sequence sessions. Ten focused minutes a day sharpens arc control faster than an hour of aimless welding.

Storing, Drying, and Reconditioning Welding Sticks

The flux coating on a welding stick does more than look official. It stabilizes the arc, generates the shielding gas that keeps air out of the molten puddle, and forms the slag that protects the cooling weld. Let that coating absorb moisture and the rod loses its one job — no matter how good your technique is.

The Moisture Problem

Steel and the minerals in flux coatings are hygroscopic, meaning they pull water from the air. Damp electrodes commonly produce excess spatter, porosity, and an unstable arc that pops and wanders instead of running smooth. That moisture also splits into hydrogen at arc temperature, and hydrogen trapped in a weld is a leading cause of cracking. The AWS structural welding code treats electrode storage and exposure as a controlled variable for exactly this reason.

Cellulosic vs. Low-Hydrogen: Two Very Different Rules

Not all sticks age the same way, and mixing up the storage rules ruins electrodes fast.

• Cellulosic rods (E6010, E6011): These rely on organic binders in the flux to create the protective gas shield. They must not be baked at the 250–300°F cycles used for E7018. That heat destroys the organic binders, and once they’re gone the gas shield is gone. Ironically, E6010 and E6011 tolerate a little surface moisture better than low-hydrogen rods, but a soaking wet cellulosic rod still runs poorly.
• Low-hydrogen rods (E7018): These absorb atmospheric moisture aggressively. Once the sealed container is opened, they belong in a holding oven — not a toolbox, not a shelf, and definitely not a damp garage floor.

Holding Ovens and Rod Ovens

A holding oven keeps low-hydrogen electrodes warm and ready, typically holding at 250–300°F so moisture never gets a foothold. A separate rod (rebaking) oven is used to recondition electrodes that have already picked up moisture, baking them back to a dry state at the manufacturer’s specified temperature.

The distinction matters: a holding oven maintains dryness, while a rebaking oven restores it. Overheating either one, or using the wrong cycle on cellulosic rods, does more harm than good. For shop layout, ventilation, and where to place that oven, see our guide to planning and setting up a safe welding shop.

When you pull a fresh can of E7018 open, the clock starts. Keep a small daily supply in the holding oven and leave the rest sealed. If you’re working outdoors or in a humid shop, an airtight rod guard with a desiccant canister buys you extra time before rebaking is necessary.

How Long Can Low-Hydrogen Rods Be Exposed?

Even after opening, low-hydrogen electrodes can sit out for only a limited window. A widely followed rule is no more than four hours of exposure before they need rebaking. In humid weather, tight jobs, or code work, that window shrinks. If you’re running structural welds and referencing settings like our 3/16 E7018 amperage breakdown, treat exposure time with the same seriousness.

Signs a Rod Is Wet

You don’t need a lab to spot trouble. Watch for:

• Excessive spatter that the amperage setting can’t explain
• Porosity pinholes scattered across the bead
• An arc that hisses, pops, and refuses to settle
• Slag that flakes oddly or traps underneath

If switching to a fresh rod fixes the problem, moisture was the culprit. Miller’s guidance on common stick electrodes notes that stable, dry rods arc differently — smoother and quieter — which is why experienced welders notice a bad batch almost instantly.

Get storage right and your welding practice actually pays off, because you’re building skill on reliable electrodes instead of fighting moisture. Keep low-hydrogen rods in a holding oven, leave cellulosic rods out of the baking cycle, and rebake only when the rules call for it.

Stick Welding Safety: Fume, Arc Flash, Burns, and PPE

Stick welding earns its tough-guy reputation, but the process punishes careless operators. Every arc throws ultraviolet radiation, molten spatter, and a cloud of metal fume straight into your breathing zone. Understanding those hazards, and matching your protection to them, keeps you welding for decades instead of sitting in a clinic.

Welding Fume: The Invisible Hazard

SMAW is a heavy fume producer. In a NIOSH-cited study, stick welding generated roughly 13 mg of fume per gram of electrode consumed, the highest normalized rate among common arc processes. That flux coating which shields your weld also vaporizes into a fine particulate cloud.

The chemistry matters as much as the volume. Manganese in the fume can accumulate in the nervous system, and prolonged exposure can cause Parkinson’s-like symptoms. Stainless electrodes are worse because they can contain chromium and nickel, which form hexavalent chromium, Cr(VI). OSHA sets its permissible exposure limit for Cr(VI) at just 5 µg/m³ as an 8-hour time-weighted average, because the compound is highly toxic and can cause cancer.

NIOSH recommends reducing exposure to all welding emissions to the lowest feasible concentrations, which is why ventilation is non-negotiable indoors.

Remember that the electrode and base metal drive fume chemistry. Galvanized coatings, paints, and stainless alloys produce especially aggressive emissions, so strip coatings where you can and never weld galvanized steel without strong ventilation.

Ventilation and Fume Extraction

Good airflow beats a mask you keep fogging up. In a fixed shop, natural draft is rarely enough; use mechanical ventilation or a fume extractor with a capture hood placed close to the arc. A welding table with downdraft extraction works well for bench work. When you weld in a confined space or on stainless, use local exhaust ventilation plus a NIOSH-approved respirator rated for particulates and metal fumes. A basic dust mask is not enough.

Good shop layout makes the job easier; build extraction, screening, and fire protection in from the start when you set up a safe shop.

This matters doubly if you are welding while pregnant or in a shared space. For those situations, check dedicated guidance before striking an arc.

Arc Eye, Burns, and Skin Damage

The arc emits intense UV and infrared radiation. A few seconds of an unshielded glance causes arc eye, a painful flash burn of the cornea that feels like sand in your eyelids hours later. It is entirely preventable.

Wear an auto-darkening helmet set to the right shade for your amperage, typically shade 10 for lighter work and climbing to shade 13 or 14 for heavy current. Choose one that also covers your neck. Bare skin is vulnerable too, since UV from an arc can burn like the sun, so long sleeves, leathers, and proper welding-grade eye and face protection are baseline, not optional.

Beyond the light, the real burns come from spatter. Leather gloves, a leather jacket or apron, and boots with no exposed cuffs stop molten metal from finding skin.

Choose PPE that matches the process:

• Eyes and face: auto-darkening helmet, shade 10–14
• Hands: leather welding gloves, gauntlet style
• Body: leather jacket or apron, long sleeves, cuffless trousers
• Feet: leather boots, no exposed laces
• Lungs: extraction first, respirator when needed

Electric Shock and Fire

Stick welders run open-circuit voltages high enough to kill, especially in wet or damp conditions. Keep gloves and clothing dry, inspect leads and electrode holders for damage, never weld in standing water, and make sure the machine is properly grounded. A little rust won’t kill you, but a frayed stinger lead on a damp concrete floor can.

Finally, sparks travel. Clear the area of rags, paper, and flammable vapors, and keep a fire extinguisher within reach. After you finish, stay and watch the work area for at least 30 minutes; smoldering fires often start after you pack up.

Common Welding Stick Mistakes and How to Fix Them

Even seasoned welders run into hiccups with welding sticks, but most faults come down to setup, not luck. The key is spotting the cause early and correcting it. Below are the most frequent issues and how to fix them without wasting rods or compromising strength.

Arc Starts, Sticking, and Polarity

Hard Arc Starts: If your rod sputters or won’t strike, check your amperage first. Too low makes ignition tough, while a cold work clamp adds resistance. Grind a clean contact point and try a short, firm tap-strike rather than a long scratch.

Rod Sticking: Sticking usually means amperage is too low, or you’re holding too long at the start. Increase in small increments for your electrode diameter, and practice a quick lift after striking. For rods that tend to freeze, a steady hand and proper arc length help immensely.

Rough, Spattery Arc: Wrong polarity is a common culprit. For example, running DCEP-only E6010 on AC won’t work, leading to excess spatter and poor stability. Always match polarity to your electrode, as outlined in TIG Welding Polarity: DCEN, DCEP, and AC Explained for Precision Welds. If you’re unsure, verify against the AWS code for your rod.

Bead Defects: Porosity, Spatter, Undercut, and Penetration

Porosity: Tiny holes often stem from moisture, rust, oil, or paint. Clean the joint to bare metal, use dry electrodes, and avoid long arcs that pull in air. In damp shops, this ties directly to the storage advice found in Welding Facilities: How to Plan & Set Up a Safe Shop.

Excess Spatter: Aside from polarity, spatter spikes with too high amperage or an overly long arc. Shorten your arc to roughly the rod diameter, dial back heat slightly, and maintain a consistent travel angle. These tweaks also improve control for those building consistency through Welding Practice: The Complete Guide to Building Real Welding Skills.

Undercut: A groove melted into the base metal weakens the toe. It often comes from excessive travel speed, too much amperage, or a steep drag angle. Slow slightly, focus heat on the joint, and pause on the edges when weaving.

Lack of Penetration: If the root isn’t fusing, your heat, joint prep, or electrode choice is likely off. Use a proper root opening, increase amperage within range, or switch to a deeper-penetrating rod. For context on other processes, see Gasless MIG Welding: The Complete Guide to Flux-Cored Welding Without Gas.

Slag, Cracks, and the Overlap Trap

Slag Inclusions: Trapped slag is almost never the electrode’s fault. Instead, slag inclusions typically come from travel-speed or cleanup errors between passes, not from the electrode itself. Remove slag fully with a chipping hammer and wire brush before each pass, and avoid weaving too wide for the puddle.

Cracked Welds & Hydrogen: Hydrogen-induced cracking is a top cause of weld failure in hardenable or thick steels. It’s mitigated by low-hydrogen electrodes, clean metal, and preheat. For these jobs, reach for E7018 or other low-hydrogen rods, preheat per the base metal, and keep them dry. OSHA’s welding guidance reinforces these precautions, especially for structural work.

Overlap: A common neighbor to cracking is overlap, where filler rolls over the base metal without fusing. This is a fusion fault, not a buildup goal. Learn the distinction in Overlap Welding Defect: Causes, Detection & Repair to avoid mistaking a cold bead for reinforcement.

Quick Stick Troubleshooting Table

With these fixes, most stick welding faults become one or two adjustments. Keep safety front and center with proper Protective Eyewear for Welding: What to Wear & Why, and refer to NIOSH welding safety resources for added guidance. Small corrections now save major repairs later.

Stick vs MIG vs TIG vs Flux-Core, and Final Takeaways

By now you’ve seen the whole picture: welding sticks are simple, rugged, and astonishingly capable in the places where fancier processes give up. Here’s how SMAW stacks up against its three closest rivals.

Stick’s superpower is wind resistance. Because the flux coating generates its own shielding gas and slag, stick welding needs no external shielding gas, so it performs in wind where MIG and TIG struggle. That’s why it dominates field work, pipelines, and farm repairs. If you want wire-feed convenience without a bottle, look at gasless MIG welding, though it’s worth knowing whether flux core is the same as MIG before you buy.

Fume exposure is where MIG and TIG pull ahead. GMAW produces far less fume per gram of filler than SMAW, and TIG produces the least fume of the common arc processes. Stick’s heavier smoke is manageable with ventilation and a respirator, as OSHA’s welding guidance explains.

Where wire processes win is speed. MIG lays down filler faster than stick and is easier to learn, with a continuous arc and less slag to chip. Flux-core splits the difference, offering higher deposition than stick with gasless operation outdoors — just get your polarity for flux core welding right. TIG is the slowest and hardest of the four, but it delivers unmatched precision, which is why thin-wall and aerospace work live there. On current, the same rules of TIG welding polarity that guide precision work also sharpen your understanding of stick settings.

Ten Principles to Remember

1. Match the electrode to the job: E6011 or E6010 for dirty, open-root work; E6013 for easy general welding; E7018 for strength.
2. Read the code: the first two digits are tensile strength, the third is position, the fourth is coating and current.
3. Set amperage by diameter — 1/8 in rods typically run about 90 to 130 amps.
4. Get polarity right; most rods are DCEP, but E6011 runs on AC or DCEN.
5. Keep arc length tight, about the diameter of the bare rod core.
6. Manage travel angle: a slight drag for most joints, straight for vertical.
7. Clean slag between passes to avoid inclusions.
8. Store E7018 in a rod oven; low-hydrogen rods absorb moisture.
9. Wear full PPE: hood, gloves, leathers, and eye protection.
10. Practice deliberately — consistency beats raw hours.

Your Beginner Action Plan

• Buy a DC-capable stick welder and a small assortment of 3/32 in and 1/8 in rods.
• Set up a safe, ventilated shop corner before your first arc.
• Burn through plate coupons: strike, hold the arc, run beads, chip slag.
• Follow a structured welding practice plan to build real skill.
• When you later add a wire machine, our guide on how to use a wire welder covers setup.

Stick welding rewards patience and punishes sloppiness, but that’s exactly why it builds good habits. Start with a handful of rods, a scrap plate, and the willingness to inspect your own work. The welds that hold for decades are made by people who kept practicing — and there’s no reason that can’t be you.

Frequently Asked Questions

What are welding sticks called officially?

The everyday term ‘welding stick’ refers to a covered stick electrode used in Shielded Metal Arc Welding (SMAW), also known as stick welding, manual metal arc (MMA), or arc welding. The metal core acts as filler while the flux coating provides shielding gas and slag.

What is the difference between E6011 and E7018?

E6011 is a 60,000 psi, all-position cellulosic electrode with a deep, forceful arc that runs on AC or DC and tolerates dirty or rusty steel. E7018 is a 70,000 psi, low-hydrogen iron-powder electrode for structural work on thicker, cleaner steel that must be kept dry in storage.

What size welding stick should a beginner use?

Most beginners start with 3/32-inch (2.4 mm) or 1/8-inch (3.2 mm) E6013 because it strikes easily and runs smooth. Use smaller rods for thin metal and larger rods (5/32 in or 3/16 in) for thick plate and higher-deposition jobs.

Can you use welding sticks outdoors?

Yes — stick welding is one of the best outdoor processes because the flux coating generates its own shielding, so wind doesn’t blow the protection away the way it does with gas-shielded MIG. This is why stick is the standard for pipelines, farms, and field repair.

Why does my welding rod keep sticking?

Rod sticking usually means amperage is too low, the arc length is too short, or the rod is damp. Raise the amperage slightly, strike with a firm tap or scratch motion, and check that the flux coating is dry and undamaged.

Do welding sticks go bad?

Yes, moisture absorption degrades them. Cellulosic rods like E6010/E6011 should be kept dry but never over-baked, while low-hydrogen rods like E7018 need a holding oven and can only be exposed to air for a limited time before requiring re-drying.

What polarity do welding sticks use?

It depends on the electrode. E6010 is DCEP (electrode positive) only, E6011 and E6013 run on AC or DC, and E7018 runs on AC or DCEP. Using the wrong polarity causes a rough, unstable, spattery arc.

Is stick welding dangerous to breathe?

Yes. Welding fume can contain manganese, hexavalent chromium, and other metals linked to respiratory damage and cancer. OSHA sets specific exposure limits, and NIOSH recommends reducing all welding emissions to the lowest feasible level through ventilation and, where needed, respiratory protection.
