Stick Welding Settings: Amperage, Polarity & Electrode Charts That Actually Work

A hobbyist bought a used 160-amp buzz box, clamped a 1/8 in 7018 rod into the stinger, cranked the dial to 140, and spent two hours chasing an arc that either stuck to the plate or blew a hole through it — the welder was never the problem. Stick welding settings are a small set of numbers (amps, polarity, arc force, arc length) that decide, within seconds, whether you get a clean fused bead or a night of grinding.

Why Stick Welding Settings Decide Everything (And What This Guide Covers)

A hobbyist picked up a used 160-amp buzz box at a yard sale, clamped a 1/8 in E7018 rod into the stinger, and turned the dial to 140 because it “sounded like a big number.” Two hours later he had a pile of stuck rods, three blown holes in 16-gauge sheet, spatter across the bench, and a growing conviction that stick welding was a cruel joke. The machine was never the problem. The settings were. Within about ten seconds of striking the arc, three numbers — amperage, polarity, and rod diameter — had already decided whether he’d get a clean fused bead or a night of grinding.

That gap between frustration and control is exactly what this guide is built to close. If you searched stick welding settings, you don’t want a lecture on arc physics. You want a dial-in reference you can carry to the machine, read in thirty seconds, and trust — a chart that tells you what to set before you strike, and a troubleshooting table that tells you which knob to turn when the bead goes wrong.

What “Settings” Actually Means for SMAW

In shielded metal arc welding, “settings” is a small set of variables, and every one of them is in your hands:

• Amperage — the current flowing through the arc, and the single biggest lever you control. It drives penetration, bead width, travel speed, and how hot the rod burns.
• Polarity — whether the electrode runs DCEP (electrode positive), DCEN (electrode negative), or AC. Polarity decides where the heat goes: into the plate or into the rod.
• Arc force / dig — a machine feature that pumps in extra current when the arc shortens, helping the rod punch through without sticking.
• Hot start — a brief current boost at arc ignition, which is a gift for cold 7018 starts and a hazard on thin sheet.
• Arc length — the gap between rod tip and puddle, held by your hand, not a dial. Keep it roughly equal to the rod core diameter.
• Travel speed — how fast you move the puddle, which controls bead profile and heat input.

Here’s why stick punishes mistakes harder than MIG. In MIG welding, the machine regulates wire feed and current automatically; a MIG setup routine handles much of the consistency for you. With stick, the consumable is consumed in your hand — you control arc length, work angle, and travel speed in real time, and the flux coating changes the arc’s behavior as it burns. A slight setting error that MIG would mask becomes a stuck rod or a blow-through. That’s also why stick remains the go-to in field, pipeline, maintenance, and structural work: one machine and a handful of consumables cover nearly every steel joint you’ll meet.

How This Guide Is Organized

We’ll move from the rod to the machine to the job:

1. Decode the AWS electrode number so you know what a rod wants before you clamp it.
2. Use the master amperage chart by rod diameter and plate thickness.
3. Choose polarity — DCEP, DCEN, or AC — with a comparison table.
4. Run a repeatable machine setup routine, including arc force, hot start, and open-circuit voltage.
5. Adjust settings by job: thin sheet, tubing, structural plate, and open roots.
6. Compensate for welding position, then troubleshoot porosity, undercut, sticking, and spatter with the exact dial to turn first.
7. Close with the safety, fume, and code side of settings, plus a 30-day practice plan.

If you’re brand new to the process, start with Is Stick Welding Hard? An Honest Beginner’s Guide for the fundamentals, then come back here when you’re ready to dial in numbers.

A Safety Standard Before the First Arc

Settings are not just a performance choice, they’re a safety choice — higher amps and bigger rods mean more heat, more spatter, and more fume. Under OSHA’s welding, cutting and brazing standard (29 CFR 1910.252), employers must control sparks, fumes, and fire exposure for every arc welding operation, and OSHA’s welding topic page is the fastest route to the full requirement set. The reference safety document for the trade is ANSI/AWS Z49.1, Safety in Welding, Cutting, and Allied Processes, published by the American Welding Society. We’ll revisit the fume and PPE implications of settings in detail later in the guide.

Note: A practical starting point many welders use is roughly 1 amp per 0.001 in of electrode diameter. A 1/8 in (3.2 mm) rod therefore starts life near 115–125 A before you fine-tune it up or down by 10–15 A based on bead appearance. Treat it as a launch point, not a rule — manufacturer data sheets and real-world conditions always win.

Read the Rod First: What the Electrode Code Tells You About Your Settings

Before you touch the amperage dial, read the rod. The four digits (and any letters) printed on the electrode covering are a factory spec sheet that already tells you roughly where your machine needs to be. The system is maintained under the American Welding Society’s filler metal specifications, so once you learn to decode it, the same logic applies to almost every stick electrode you’ll ever buy (AWS).

Decoding the AWS Electrode Classification

Take E7018 and break it apart:

• E — the electrode is designed for arc welding.
• 70 — minimum tensile strength of 70,000 psi (483 MPa). An E6011 rod gives you 60,000 psi (414 MPa). This number is your match to the base metal’s strength.
• 1 — welding position. A third digit of 1 means the rod is qualified in all positions: flat, horizontal, vertical and overhead. A third digit of 2 means flat and horizontal fillet work only — think E7024 on heavy flat fillets.
• 8 — the covering type, which controls arc characteristics, slag, penetration and hydrogen. The fourth digit ranges from 0 to 8, and it’s the biggest reason two rods with the same tensile number behave completely differently.

Letters after the digits add hydrogen information. On E7018 H4, the H4 means the covering is limited to a maximum of 4 ml of diffusible hydrogen per 100 g of deposited weld metal; H8 allows up to 8 ml, H2 up to 2 ml. Lower hydrogen means less risk of hydrogen-induced cracking in restrained, high-strength joints.

The Five Rods That Cover About 90% of Jobs

You don’t need a warehouse of electrodes. A hobbyist or small shop stocked with the rods below can handle nearly anything.

Rod	Typical Polarity	1/8 in Amp Window	Penetration	Best For
E6010	DCEP	70–120 A	Deep, digging, narrow	Root passes, open roots, rusty or painted plate, pipe
E6011	AC or DCEP	60–120 A	Deep, forceful	Field repair, dirty metal, farm work, thin-wall pipe
E6013	AC, DCEN or DCEP	90–130 A	Shallow, soft	Sheet metal, beginners, cosmetic beads
E7018	DCEP (AC versions exist)	110–165 A	Moderate, clean	Structural, code work, low-hydrogen applications
E7024	DCEN or AC	200–300 A	Moderate, shallow angle	High-deposition flat and horizontal fillets

Quick Note: The numbers above are typical published windows, not gospel. Every carton carries the manufacturer’s data sheet with the recommended range for that specific diameter and batch — check it before you strike an arc, because your rod’s range can differ from the next brand by 15–20 amps.

The split in personality comes from the coating. Cellulose rods (6010, 6011) burn hot and dig deep, which is why they’re the go-to for root passes on pipe and rusty farm repairs but also why they sound harsh and spatter more. Rutile rods (6013) run a soft, quiet, shallow arc that forgives sloppy arc length — perfect when you’re learning on sheet. See how rod choice alone shifts your technique in What Are Electrodes in Welding? Types, Numbers, Polarity & How to Choose.

Why 7018 Is Different: Low-Hydrogen Handling

E7018 is a low-hydrogen, iron-powder electrode and the default structural rod for code work. Its flux is designed to keep hydrogen out of the weld puddle — but only if you keep moisture out of the flux. A 7018 exposed to shop humidity picks up water, the arc drives hydrogen into the bead, and you get porosity or, worse, cracking you can’t see.

That’s why 7018 rods live in a holding oven at roughly 250 °F (120 °C) between uses, and why rods that have gone soggy need manufacturer-approved re-drying before they touch a joint — follow the exact time and temperature on the carton, because over-baking damages the covering too. Sealed cans and rods left out overnight are a real source of “mystery porosity.”

Hydrogen control isn’t just shop folklore; it’s baked into safety and quality practice. Even at the simplest hobby level, your fume and gear discipline should follow the same standards shops are held to, which is why our Welding PPE: The Complete Guide to Protective Gear Every Welder Needs is worth a read before your first 7018 pass.

From Rod Code to Dial Setting

Once you know the rod, the settings narrow fast:

• Cellulose rods (6010/6011): DCEP or AC, higher arc force/dig, short arc, quick travel.
• Rutile rods (6013): any polarity, moderate amps, slightly longer arc tolerance.
• Low-hydrogen rods (7018): DCEP, moderate dig, drag technique, dry storage.

Note: The rod tells you polarity, hydrogen class and starting amperage — the chart in the next section tells you the exact number for your plate thickness. Read both, and the arc behaves.

The Master Stick Welding Settings Chart: Amps vs. Rod Diameter vs. Plate Thickness

If you only print one part of this guide and tape it to your machine, make it this section. Amperage is the single dial that decides whether your rod runs smooth or turns into a glue stick, and the right starting number is almost always a function of one thing: rod diameter, checked against the thickness of the metal in front of you.

The Master Amperage Chart by Electrode Diameter

The ranges below are typical published SMAW amperage windows aggregated from electrode manufacturers and classic welding handbooks. Think of them as your search zone, not a fixed commandment. Your exact number lives inside the window, and you find it by reading the bead.

Rod Diameter	Typical Amperage Range	Best Suited Plate Thickness	Common Use
1/16 in (1.6 mm)	30–60 A	24–18 gauge sheet	Thin sheet, tack welds, repair on light tubing
3/32 in (2.4 mm)	55–90 A	Under 1/8 in (up to ~3.1 mm)	Light fabrication, out-of-position work, root passes
1/8 in (3.2 mm)	90–140 A	1/8–3/16 in (3.1–4.8 mm)	The everyday shop size; brackets, plate, general repair
5/32 in (4.0 mm)	130–180 A	3/16–1/2 in (4.8–12.7 mm)	Fillets, multi-pass flat and horizontal welds
3/16 in (4.8 mm)	160–230 A	1/4 in and heavier	Heavy structural, high-deposition passes
1/4 in (6.4 mm)	210–300 A	1/2 in and heavier	Very heavy section, hoppers, thick plate buildup

Electrode type nudges you within those windows. A 1/8 in E7018 is commonly run at roughly 110–165 A on DCEP, sitting toward the hotter side of the 1/8 in band, while a 1/8 in E6013 likes about 100–130 A and gets cranky above it. If you are running the small-diameter low-hydrogen rods, our dedicated 3/32 E7018 amperage guide walks through that exact window, and the 5/32 E7018 guide covers the step up.

Quick Note: Rod diameter ≈ plate thickness is the fastest rule in stick welding. For butt joints on plate up to about 1/4 in, pick the rod that matches the metal’s thickness, then dial the amps inside the chart window. If your rod is 1/8 in and your plate is 1/8 in, you are already close to right.

Matching Rod Diameter to Plate Thickness

The chart’s thickness column deserves a closer look, because picking the wrong diameter is the mistake behind most blown corners and cold laps:

• Under 1/8 in material: drop to 3/32 in or smaller. A 1/8 in rod simply dumps more metal than thin stock can absorb.
• 1/8 to 3/16 in material: 1/8 in rod. This is the sweet spot for most hobby and light-fab work.
• 3/16 to 1/4 in material: 5/32 in rod gives you the deposition and penetration without stalling the arc.
• Heavier than 1/4 in: 3/16 in or larger, usually with multiple passes rather than one monster bead.

Fit-up changes the math. A joint with a wide gap or heavy clamping acts as a heat sink, so back off 10–20 A from the chart value and let the joint tell you when to add it back. Joints, gap bridging and fit-up tolerance are covered in depth in our pipe welding procedures guide, and the same logic applies to open-root plate work.

Fine-Tuning: The ±10–15 A Method

Set your machine at the middle of the chart window, run a 3-inch bead on scrap of the same thickness, clean off the slag and read it. This is the part beginners skip and pros never do without:

• Bead too narrow, tall and crowned, with harsh ripple: amperage is too low. Raise it 10 A and try again.
• Bead flat, wide, washed out at the edges with heavy spatter: amperage is too high. Drop 10 A.
• Bead flat in the middle but with visible toes that haven’t blended: usually travel speed or arc length, not amps.

Move in 5–10 A steps, not 30. You are converging on a number, and the bead is your readout.

Note — The Heat Input Equation: Amperage is only half the thermal story. Heat input in kJ/mm ≈ (60 × amps × volts) ÷ (1000 × travel speed in mm/min). Higher amps and slower travel both push heat input up, which means more distortion, coarser grain and, on stainless, more sensitization risk. If distortion is fighting you, cut amps before you cut technique.

One final caveat: every manufacturer publishes slightly different windows for the same classification, and machine calibration drifts. Treat the numbers on the rod carton as the last word, keep spare cable connectors clean and tight so your dial setting actually reaches the arc, and for thin-gauge work specifically, see stick welding thin metal settings before you touch the dial.

DCEP, DCEN or AC? Choosing Polarity for Stick Welding

Polarity is the one setting most beginners never touch, yet it decides how deep your rod digs, how fast it deposits metal, and how the arc behaves when you hit a corner. Once you get it, you never guess again.

The Physics in Plain English: Heat Follows the Anode

One fact makes everything else make sense: in a DC welding arc, roughly 70% of the heat is generated at the anode. Electrons stream from the cathode to the anode, and their impact releases far more energy at the positive side. So the only real question is which side is the anode, the rod or the plate?

• DCEP (Direct Current Electrode Positive), also called reverse polarity, makes the electrode the anode. The rod runs hotter, the arc cone tightens, and the workpiece receives a concentrated, deep-penetrating beam. This is why DCEP is the standard for root passes and dirty or thick material.
• DCEN (Direct Current Electrode Negative), also called straight polarity, flips it: the workpiece becomes the anode. The electrode takes most of the heat, melting filler off the rod faster and shallower. Deposition rate goes up, penetration goes down.

Quick Note: If you remember one sentence from this section, make it this: DCEP digs, DCEN fills. Deeper penetration on DCEP, faster metal deposition on DCEN.

What Each Polarity Does to Your Weld

Factor	DCEP (Reverse)	DCEN (Straight)	AC
Penetration	Deep and narrow	Shallow, broader	Moderate, between DC options
Deposition rate	Moderate	High	Moderate
Arc stability	Stable on 6010/7018	Stable on 6013/7024	Slightly rougher on DC-only rods
Typical rod compatibility	E6010, E6011, E7018	E7024, some E6013	E6013, AC-rated 7018s, E7014
Best use	Root passes, pipe, dirty steel, structural	Fast fill on flat plate, thin sheet	Engine-driven machines, arc blow situations

For a full treatment of small rods on sheet, see our 3/32 E7018 amperage, polarity and technique guide; for larger structural rods, the 5/32 E7018 settings guide.

Factory Polarity: What the Rod Was Designed For

Manufacturers formulate coatings around a specific polarity. Ignoring that recommendation is one of the most common causes of mysterious spatter and arc instability.

• E6010 and E6011: built for DCEP. E6011 adds AC capability for engine-driven machines. These cellulose rods want a crisp, digging arc; on DCEN they stutter and spit.
• E7018: typically DCEP on DC, with many sizes also carrying an AC classification for welders without stable DC output. For the full low-hydrogen family breakdown, read what electrodes in welding really are: types, numbers and polarity.
• E6013: rated for AC, DCEP or DCEN. It runs acceptably anywhere, which is why it’s the classic beginner rod.
• E7024: the fast-fill rod, commonly run on DCEN or AC. Its heavy iron-powder coating needs the electrode-hot condition of DCEN to burn efficiently in flat and horizontal work.

When AC Earns Its Place

Alternating current swaps polarity 100 or 120 times per second, so neither side holds a heat monopoly. That matters in two situations. Engine-driven welders often default to AC, narrowing you to AC-rated rods. More practically, AC cures magnetic arc blow: when DC current flows into a plate end, a corner, or a poorly placed ground clamp, the magnetic field around the arc pushes it sideways. The arc wanders, the puddle crawls unevenly, and spatter rises at the termination of a joint.

Fix it in this order:

1. Move the ground clamp closer to the weld and on the same side of the joint.
2. Reduce amperage slightly and shorten the arc.
3. Switch to AC if your machine offers it; the field cancels over each half cycle, which usually ends arc blow.

How to Test Polarity on Your Own Machine

Quick Note: Before striking an arc, confirm polarity at the DINSE connectors, not just the machine dial. Cable swaps and worn plugs are common on used machines. The electrode holder belongs on the (+) terminal for DCEP and the (−) terminal for DCEN. For installation and troubleshooting, our welding connectors explained guide covers it.

Switching polarity costs nothing but two minutes. Cut a scrap coupon, run three short beads with the same rod at 100 A on DCEP, DCEN and AC, then compare penetration, bead width and spatter with a chipping hammer. That single experiment teaches more than a paragraph can. If penetration looks thin on a root pass, check the rod’s recommended polarity before blaming your technique.

For a broader grounding in the fundamentals behind all of this, our honest beginner’s guide to whether stick welding is hard walks through the same learning curve most welders experience.

A reversed cable won’t damage the machine, but it does change fume characteristics and arc behavior enough to surprise you mid-joint, and hot slag releases differently on each polarity. Standard welding PPE stays mandatory regardless of which terminal you choose, and OSHA’s welding, cutting and brazing standards apply to every polarity setting you’ll ever run.

Dialing In the Machine: Step-by-Step Stick Welder Setup

Knowing the right amperage is only half the job. The other half is walking up to the machine and setting it the same correct way every single session, so the only variable left is your hand. Welders who struggle for twenty minutes before every weld are usually skipping steps in the setup, not lacking talent. Here is the routine worth memorizing.

The Six-Step Setup Routine

1. Confirm supply voltage and cable size. Plug into the outlet the machine was designed for and check that your leads are heavy enough for the current and length you are about to run. A 200 A machine on a long, thin extension-style cable will droop before you ever strike an arc.
2. Select polarity. Set DCEP, DCEN or AC before you pick up the rod, matching the electrode manufacturer’s recommendation. If you are unsure, our guide to electrode numbering and polarity walks through it rod by rod.
3. Set amps from the chart. Take the diameter-and-thickness value from the master chart, dial it in, then plan to adjust ±10 A by bead appearance.
4. Set arc force (dig) and hot start. Start moderate on both and tune from there.
5. Clamp the ground to the workpiece. Not the table alone, not the vise, not a bench leg. Direct metal-to-metal contact on the piece you are welding, as close to the joint as practical.
6. Strike, weld a short bead, then judge. Ten seconds of bead on a scrap coupon tells you more than any dial marking.

Quick Note: If the arc feels mushy and unstable but your amps look right, check the ground clamp before touching the dial. A weak ground is the single most misdiagnosed setup fault in stick welding.

Why Stick Requires a Constant-Current (CC) Machine

Stick welding demands a constant-current power source. Your arc length changes constantly, millimetre by millimetre, because you are doing it by hand. A CC machine is built so that these small changes in arc length do not produce large, destabilizing swings in current. Voltage rises and falls as the arc stretches; the amperage stays close to what you set. Without that characteristic, every slight wrist movement would surge or starve the arc, and a stable bead would be impossible.

Arc Force (Dig) and Hot Start

Arc force, often labelled dig, is a momentary current boost that kicks in when the arc shortens and is about to stick to the work. It is usually expressed as a 0–100 percentage or as extra amps above your set point.

• Cellulose rods (E6010, E6011) want high dig, typically 60–100%. They run a short, forceful arc and dig hard into the root; without enough dig they freeze to the plate.
• Low-hydrogen rods (E7018) prefer moderate-to-low dig. Crank it up and the bead turns rough, forceful and spattery instead of smooth and buttery. Settings for 3/32 E7018 and 5/32 E7018 both assume a restrained dig setting.
• Thin metal: too much dig causes burn-through. Back it off on 16-gauge.

Hot start is a separate feature: a brief current boost at arc ignition that helps a cold 7018 rod light up cleanly instead of sticking on the first tap. It is genuinely useful on heavy plate, but on 16-gauge sheet that same boost will blow a hole before the rod is even moving. Turn it down or off on thin material.

Open-Circuit Voltage, VRD and the Supply Side

Open-circuit voltage (OCV) on stick machines typically sits in the 60–80 V range before the arc is struck. Because that idle voltage is a shock hazard, many machines carry a voltage reduction device (VRD), which drops the idle output to roughly 30–35 V until the circuit is closed. OSHA’s welding, cutting and brazing requirements under 29 CFR 1910.252 set the framework for grounding, ventilation and safe equipment use in the shop, and OSHA’s welding topic page is the fastest place to check current expectations.

The supply side matters just as much. NEC Article 630 covers feeder and branch-circuit sizing for electric welding units, and long or undersized leads create voltage drop that shows up exactly where you notice it: an unstable, mushy arc that refuses to run cleanly no matter what the dial says. If your leads get warm at the connectors, or the arc softens as you work farther from the machine, the fix is heavier cable, shorter runs, or tighter connections. Proper cable connectors that are clean and torqued matter more than any premium rod.

Note — Keep It Maintained: Clean the DINSE threads and cable lugs, keep every connection tight, and store low-hydrogen rods dry and warm. A dirty connector or a damp 7018 rod will undo a perfect settings routine in one pass.

Settings by Job: Thin Sheet, Tubing, Structural Plate and Open Roots

Charts assume a clean flat coupon sitting on a bench. Real work shows up as 18-gauge sheet, rusty angle iron, square tubing and an open root with bad fit-up. This section translates the master chart into the four job families you will actually meet, so you can walk up to any joint and set the dial with confidence.

Thin Sheet (16–18 Gauge): Stay Small, Stay Cool

Sheet at 0.05–0.075 in has almost no heat sink: the moment your arc lingers, cherry red turns into a hole. For 16–18 gauge mild steel, most welders drop to a 1/16 or 3/32 in E6013 at roughly 35–55 A and lean on short tack welds before joining anything. Small rods matter more here than anywhere else. A 1/16 in rod at 40 A deposits a puddle the sheet can absorb; a 1/8 in rod, even turned down, dumps too much arc energy into too small an area.

Work in short stitches or a backstep sequence, keep the arc length near 1/16 in, and keep moving. If thin material is new to you, our stick welding thin metal guide walks through amp settings and burn-through fixes in depth, and stick welding sheet metal covers rod choice for the thinnest stock. Stick also is not the only option here, so it is worth understanding how a spot welder works before you fight a losing battle with a 6011 rod.

Quick Note: Settings Cheat Sheet by Thickness

• 16–18 gauge (0.05–0.075 in): 1/16–3/32 in E6013, 35–55 A, short tacks, 1/16 in arc
• 1/8 in plate: 1/8 in rod, 95–125 A, flat butt or fillet
• 3/16–1/4 in plate: 5/32 in rod, 140–175 A, stringer passes
• 1/2 in and heavier: 3/16–1/4 in rod, 200–280 A, multi-pass with interpass cleaning
• Open root: 1/8 in E6010 on DCEP, 90–110 A, keyhole technique

Tubing and Thin Angle: Watch the Corners

Square tubing and thin angle iron behave like sheet at the corners and like plate along the runs. Heat races into a corner because the material there acts as a heat sink on two axes at once, then suddenly there is not enough metal left to hold it. Set amps as if you were welding sheet, use the smaller rod, and stop your bead a half-inch short of the corner, then reposition and finish it. Tack all four corners before running any bead: the tacks themselves act as heat sinks that stabilize the joint.

1/8 in Plate: The Everyday Sweet Spot

Most farm repairs, brackets and general fabrication live on 1/8 in mild steel, which is why it is the ideal training ground. A 1/8 in butt joint or fillet is typically welded with a 1/8 in rod in the 95–125 A range, with a 1/16 in arc length. If you are running 7018 on this thickness, our 3/32 E7018 amperage guide shows how much smaller the window gets when you step down a rod size.

3/16–1/4 in Plate: Step Up and Stringer

Structural plate in the 3/16–1/4 in range wants a 5/32 in rod at 140–175 A. This is thick enough to accept a stringer bead without weaving, and the extra current gives you the penetration profile the joint needs. For a complete look at dialed-in 5/32 settings, see our 5/32 E7018 amperage guide.

At 1/2 in and heavier, switch to a 3/16 or 1/4 in rod at 200–280 A and think in passes: a root pass, a hot pass, then cover passes to cap the joint. Multi-pass welds require interpass cleaning, a chipping hammer plus a wire brush, because every pass lays down slag that will poison the next one if you leave it. Chip, brush, inspect, then weld.

Open Root and Pipe: Control, Not Heat

The open root is where settings discipline pays off. Open roots are classically welded with E6010 on DCEP using a keyhole technique at moderate amperage, typically a 1/8 in rod at 90–110 A, rather than cranking the heat. You are watching a small keyhole open at the leading edge of the puddle; when it opens, feed forward to close it. Too many amps and the keyhole swallows the root face; too few and the rod sticks without bridging the gap.

Fit-up decides everything here. A tight joint with no gap needs more heat or a larger rod to get through; a wide gap with thin root faces needs you to back off 10–20 A, because the joint geometry itself acts as a heat sink that pulls fusion away from the root edges. For procedures, positions and inspection criteria on this kind of work, our pipe welding procedures guide covers WPS paperwork and pass sequencing.

Note: Distortion Control Is a Settings Decision

Heat input drives distortion, so manage it like a setting. Tack generously before running beads, use clamps and fixtures to hold the assembly rigid, and choose skip-welding or backstep sequences over long continuous beads. Smaller rods at lower amps, welded in balanced passes on opposite sides of the joint, keep assemblies truer than one hot pass ever will. Our guide to tack welding explains spacing and sizing that transfers directly to stick work.

The pattern across every job: match the rod to the thinnest section you will touch, set current from the chart, then let the bead tell you whether to move the dial up or down.

Welding Position Adjustments: Flat, Horizontal, Vertical and Overhead

Every amperage chart you’ll ever find, including the one earlier in this guide, is written for one position: flat. That’s no accident. Flat welding is the reference point because gravity works with you instead of against you. The puddle sits down, the slag stays put, and the rod burns evenly. The moment you roll the plate over or crawl under it, gravity becomes an opponent, and the settings that worked in flat will fight you.

The AWS Position Symbols (1G/1F Through 4G/4F)

Before adjusting anything, it helps to speak the industry’s language. AWS position symbols run from 1G/1F (flat) through 2G/2F (horizontal), 3G/3F (vertical) and 4G/4F (overhead). The letter tells you the joint type: G for groove welds and F for fillet welds. So a 3F weld is a vertical fillet, and a 4G is an overhead groove.

The digit at the end of your rod’s classification code matters here too. A third digit of 1 (like E6011 or E7018) means the rod is qualified in all positions, while a 2 (like E7024) means flat and horizontal only. Running an all-position rod overhead is fine; running a flat-only rod overhead is a slag-controlled mess waiting to happen. For a deeper breakdown of what those digits mean, see our guide to electrode classification codes.

The 10–15% Rule: Back Off the Current

The single most useful adjustment rule in out-of-position stick welding is simple: reduce flat-position amperage by about 10–15% when moving to vertical-up or overhead work. On a 1/8 in E7018 running 120 A flat, that puts you around 102–108 A vertical. The reason is puddle viscosity. Less current means a stiffer puddle that hangs where you place it instead of dripping off the rod.

Two supporting habits make the rule work:

• Keep your rods short. Out of position, a long, whipping-hot 14 in electrode radiates heat back at your hand and gives you less precise arc control. Snap or use up rods to roughly 6–7 in for vertical and overhead passes.
• Drop to a smaller diameter. Out-of-position welding is dramatically easier with 3/32 or 1/8 in rods because they require less current and the puddle freezes faster. A 5/32 rod that behaves perfectly flat will sag badly overhead.

Flat (1G/1F)	Chart setting, no change	Any diameter suited to thickness
Horizontal (2G/2F)	Down ~5% (watch top edge)	1/8 in typical, 5/32 max
Vertical-up (3G/3F)	Down 10–15%	3/32 or 1/8 in all-position rod
Overhead (4G/4F)	Down 10–15%	3/32 or 1/8 in, short rod

Vertical-Up vs. Vertical-Down: Two Different Jobs

Vertical welding splits into two techniques that do almost opposite things.

• Vertical-up travels against gravity, so heat builds in the joint and the puddle has time to fuse deeply. It’s slower, but it produces the penetration and throat thickness structural work demands. This is the default for thick plate root and cover passes, and for pipe root passes where pipe welding procedures typically specify it.
• Vertical-down runs with gravity: fast, cool, and shallow. It’s the traditional approach for thin-walled pipe and sheet with 6010-style rods, where speed and a narrow, controlled bead matter more than deep penetration. Push it too hot and the puddle outruns the arc.

A practical reference: for overhead 7018 work, our 3/32 E7018 amperage guide shows how far down you actually need to go once you leave flat.

Horizontal Fillets: Watch the Top Edge

In a horizontal fillet (2F), gravity pulls the puddle toward the bottom plate while the arc tends to gouge the upper toe. The fix is a slight work-angle bias toward the upper plate and a short arc. If the top edge looks washed out or the bottom toe is fat and cold, you’re either too hot or favoring the wrong side. Sagging along the top toe is the classic sign of amps set for flat and never adjusted. The overhead technique fundamentals apply here too: tighter arcs and smaller rods tame almost every gravity problem.

Quick Note: When in doubt in any out-of-position weld, drop 10 amps first, shorten your arc second, and only then consider changing rod diameter. Most sagging and drip-through problems disappear with that one dial turn.

Position isn’t just geometry; it’s a heat-management problem. Adjust deliberately, test on scrap in the actual position you’ll weld in, and let the bead tell you when the setting is right.

Troubleshooting: Common Stick Welding Problems and the Setting to Change

Most stick welding defects can be traced back to a single adjustment. The key is to read the bead, find the root cause, and change one dial at a time. Below is a straightforward map to help you fix the most common issues without the guesswork.

Symptom → Cause → Setting Fix Chart

Symptom	Most likely cause	First dial to change
Rod sticks to the work	Amps too low, arc struck too short, dirty or damp rod	Raise amps 10–15 A; lengthen arc stroke
Porosity (pinholes)	Oil, paint, rust, moisture, or draft; low amps and long arc add to it	Clean the joint first, then raise amps slightly
Undercut along the toe	Too much current, travel too fast, wrong work angle	Drop amps 5–10 A, slow travel
Lack of fusion or penetration	Too little current, travel too fast, wrong electrode angle	Raise amps, slow down, hold correct angle
Excessive spatter	Long arc, wrong polarity, amps too low for the rod type	Shorten arc; verify polarity
Arc blow (arc pushes sideways)	Poor ground placement, long leads, residual magnetism	Move work clamp; switch to AC
Slag inclusions	Weak interpass cleaning, erratic travel, amps too high or low	Chip and brush every pass; normalize amps
Rough, forceful bead with spatter on E7018 (DCEP)	Dig/arc force set too high	Reduce dig dial

Reading the Bead Before You Touch a Dial

When your amperage is too low, the bead will look narrow, tall, and rope-like. It will sit on top of the plate with poor side wetting and often cause the rod to stick. Bump your current up in 10 A steps until the bead flattens and washes into both toes. If it becomes flat, saggy, or washed out with heavy spatter, you’re running too hot.

For a closer look at rod-specific windows, check out our 5/32 E7018 amperage guide to apply this process to that electrode.

Porosity is rarely the machine’s fault. Oil, paint, rust, mill scale, moisture, wind, or a draft will blow away your shielding coverage far quicker than any amp setting. Degrease with acetone, grind to bright metal, and block the breeze before nudging your amps up.

Undercut tends to stem from too much heat or speed. Excessive current, a fast travel speed, or pointing the arc towards the sidewall instead of the joint center can all gouge the toe. Drop your amps 5–10 A, slow down, and let the filler build the edge back up. Our undercut defects guide goes into more detail on acceptance and repair.

Lack of fusion or penetration is the opposite. Too little current, travel that’s too fast, or the wrong electrode angle are the usual culprits. Slow down, hold a drag angle of around 10–15°, and raise amps until the puddle wets into the root. Keep in mind that a wide gap acts as a heat sink, so you may need 10–20 A more than a flat-plate chart suggests.

Quick Note: After every short bead, run a five-second check. Is it roughly two to two and a half times the rod diameter? Does it wet smoothly into both toes with no lips? Are the ripples evenly spaced? Is the profile flat to slightly convex, not tall and ropey? Fix whatever answers no, and only change one variable.

The Final Fixes

Arc blow is magnetic, not mechanical. If the arc wanders at a plate corner or the end of a weld, reposition your work clamp closer to the joint and shorten your leads. If it persists, especially on DC, switch the machine to AC to neutralize the unbalanced magnetic pull.

Slag inclusions come from rhythm more than your rod. Travelling too fast, uneven speed, or skipping interpass cleaning can all trap slag. Chip, wire-brush, and inspect every pass, while keeping your current consistent. For multi-pass work, our pipe welding procedures guide breaks down setting adjustments for each pass.

Harsh E7018 arcs are a common complaint. If your amps look right, but your E7018 on DCEP is throwing spatter and feels rough, your dig (arc force) dial is likely set too high. Dig is great for a stubborn 6010 root, but it can overdo it for a smooth-rod 7018. Turn it down to the low-to-moderate range and the arc should soften right away.

Note: Change only one setting at a time and test with a short bead. If you’re stuck on the same defect, revisit the fundamentals in Is Stick Welding Hard? before buying new gear.

Safety, Fumes and Codes: Settings Choices Have Health Consequences

When dialing in your stick welding settings, the number on the amp dial isn’t just about penetration or bead appearance. It is also a health and compliance decision. Choosing higher amps and larger rods directly raises fume generation, arc brightness and heat input. For this reason, safety must be factored into your settings just as heavily as electrode selection or polarity.

Quick Note: Higher amps = more fume = more ventilation.

Fumes, Gases and Long-Term Health Risks

The fumes produced from shielded metal arc welding (SMAW) are a mixture of metallic oxides, silicates and, in some cases, hexavalent chromium (Cr(VI)). These byproducts are not to be underestimated. According to the International Agency for Research on Cancer (IARC), welding fumes were reclassified from Group 2B to Group 2A, meaning they are probably carcinogenic to humans following its Monographs evaluation of welding fume exposure.

Exposure to manganese, a common element in many steel electrodes, can lead to metal fume fever, neurological effects and respiratory irritation. For this reason, NIOSH welding safety guidance stresses the use of local exhaust ventilation (LEV) or approved respirators, especially in enclosed or poorly ventilated spaces. If you are working with chromium-bearing alloys, such as stainless steel, the risk becomes far more specific.

OSHA’s hexavalent chromium standard (29 CFR 1910.1026) sets a strict 8-hour permissible exposure limit (PEL) of 5 µg/m³ for Cr(VI). This limit applies when welding, cutting or brazing stainless steel and other chromium-bearing materials, making air monitoring and exposure control mandatory for many industrial jobs.

Codes, Compliance and Your Legal Responsibilities

Regardless of whether you are a hobbyist or a contractor, regulatory standards exist to protect you and those around you. 29 CFR 1910.252, OSHA’s general requirements for welding, cutting and brazing, requires adequate ventilation, guarding, fire watches, proper grounding and hot work permits when working near combustibles. On construction sites, OSHA 1926.353 reinforces these duties with specific provisions for ventilation and respiratory protection.

Before you strike an arc for heavier work, such as the jobs covered in our pipe welding procedures guide, ensure your workspace is compliant. For general shop safety, you can also reference our MIG welding safety precautions for transferable best practices. These regulations are not red tape, but preventative measures against fires, toxic exposure and electrical injury.

Personal Protective Equipment (PPE)

Even with perfect ventilation, your body still needs protection from arc radiation, sparks, slag and electrical hazards. A quality auto-darkening helmet (shade 10–12 for most stick work), FR clothing and leathers, FR gloves, and hearing protection are non-negotiable. For a full breakdown, check out Welding PPE: The Complete Guide or What Does a Welder Wear?.

Dry rod storage is just as important to your lungs. Moisture in low-hydrogen electrodes can release hydrogen and drastically increase fume-related issues, so keep rods sealed and follow the manufacturer’s re-drying instructions. Proper welding connectors also prevent arcing at terminations, a common, yet avoidable, fire risk.

Electrical Hazards and Confined Spaces

Stick welding runs on high open-circuit voltage (OCV). OSHA has raised awareness of OCV hazards, and modern machines often utilize Voltage Reduction Devices (VRDs) to drop idle OCV to roughly 30–35 V. In wet conditions, confined spaces or if your machine lacks these features, the risk of electric shock rises exponentially. For this reason, awareness of AWS safe work practices and OSHA’s electrical guidance is crucial. NFPA 70E awareness should also be considered for those working in industrial electrical environments.

Confined spaces pose a double threat: limited egress paired with rapid fume accumulation. In these cases, LEV is far more effective than a respirator alone, and a permit, monitoring and a trained attendant are often required. This is especially true for high-amp runs on thicker stock, such as the settings used in our 5/32 E7018 amperage guide.

Note: Never trade ventilation for speed. When in doubt, exhaust first, then exhaust more, and only use respiratory protection as a last line of defense or in conjunction with LEV.

Final Takeaways

Safety is built into your settings. Dropping your amps slightly for thin material can prevent blow-through, but it also reduces fume output. Utilizing the correct rod for the job, striking a short arc, and avoiding excessively long lead runs to compensate for low amps all work towards a safer weld. By adhering to industry best practices, keeping your work area dry and compliant, and treating fumes as a health hazard rather than an inconvenience, you will not only produce cleaner beads, but a longer, healthier welding career as well.

Practice Plan, Gear Checklist and Final Takeaways

After dialing in your amperage, polarity, and electrode picks, the biggest step forward is putting them to work on real metal. The settings you just learned will only stick if you train your eyes to spot the difference between a cold bead, a sweet bead, and an overheated one. With a little discipline, you can build that skill in a matter of weeks. More importantly, the U.S. Bureau of Labor Statistics tracks welding as a large skilled-trade occupation with steady demand across manufacturing, construction, and repair. That alone makes stick welding settings fluency a true career-level skill.

Your 30-Day Stick Welding Settings Practice Plan

The fastest way to lock in your numbers is by testing them with purpose. A controlled bead-on-plate test in 3-amp increments teaches you to read bead profile, wetting, and ripple spacing far quicker than any chart alone. Use this plan to build muscle memory without wasting rods:

• Days 1–7: Read and Run. Start with 1/8 in E7018 on a clean piece of mild steel. Use the chart amps for that rod, then run the ‘3-amp increment’ test: weld three identical beads-on-plate at -10 A, nominal, and +10 A. Compare each one side by side and write down your pick.
• Days 8–14: Scrap-Thickness Variety. Move onto different material thicknesses. Practice on thin stock (16–18 gauge) using the advice from our Stick Welding Thin Metal: Amp Settings, Techniques & Burn-Through Fixes guide, then bump up to 3/16 in to see how your arc changes. Keep your arc short and adjust travel speed with every jump.
• Days 15–21: Position Drills. Flat is easy, but out-of-position is where settings count. Work on horizontal, vertical-up, and overhead using smaller rods. Our Overhead Stick Welding: The Complete Guide to 4F & 4G Technique, Amperage, and Rod Selection breaks down safe, realistic ways to practice these joints without overdoing heat input.
• Days 22–30: Fix Real Mistakes. Intentionally recreate common issues like rod sticking, undercut, or lack of fusion, then correct them by changing one setting at a time. Cross-reference your fixes with Welding Defects Undercut: Causes, Acceptance Limits, and How to Fix It to solidify your troubleshooting skills.

For every coupon, chip the slag, inspect the cross-section with a wire brush, and judge fusion at the toes. This habit alone will expose weak spots before they ever reach a critical joint.

Gear Checklist: The Items That Keep Settings Honest

Keeping consumables, ground clamp and lead connections clean and tight removes a common hidden source of arc instability that is often misdiagnosed as a settings problem. Before you strike your next arc, run through this bare-minimum gear checklist:

• Striking & Cleaning: Chipping hammer and wire brush to clear slag and scale between passes.
• Measuring: Tip/pike gauge or a simple steel rule to check root gaps, fillets, and penetration references.
• Electrical Integrity: Meter-clamp if available, plus spare ground clamp and lead set. Pay extra attention to your Welding Connectors Explained: How to Choose, Install, and Troubleshoot Cable Connectors That Never Let You Down to avoid voltage drop.
• Rod Care: Rod oven or dry container for low-hydrogen rods. Never leave 7018 exposed to humidity for extended periods.
• Safety First: Full coverage leathers, FR gloves, and the correct shade helmet. Brush up on Welding PPE: The Complete Guide to Protective Gear Every Welder Needs (2026) and MIG Welding Safety Precautions: The Complete Guide to Staying Safe in 2026 to meet the OSHA welding, cutting and brazing basics.

Quick Note: Reusing rod stubs under 2–3 in, welding on a poorly grounded table, and skipping interpass cleaning are among the most common routine mistakes that no amperage change can fix.

Final Takeaways: The Five Settings Rules to Remember

With so many numbers floating around, keep your head clear by sticking to these five rules on every job:

1. Right Rod: Match your electrode to the base metal, position, and strength needed. Review What Are Electrodes in Welding? Types, Numbers, Polarity & How to Choose anytime you’re unsure.
2. Right Polarity: Know DCEP, DCEN, or AC for that rod. When in doubt, test a scrap coupon before committing to your joint.
3. Chart Amps: Start at the published range for your rod diameter. Fine-tune ±10–15 A based off of bead appearance, not guesswork.
4. Short Arc: Keep your arc length tight. A long arc almost always breeds spatter, porosity, and erratic heat.
5. Slow Enough Travel: Let the puddle fuse fully. Rushing is the root cause for more lack-of-fusion failures than most welders realize.

Consistency beats chasing new machines. The welder that can run the same clean bead at the same amps, on the same rod, in the same position day after day will outproduce the one constantly twisting dials. From Pipe Welding Procedures, to 5/32 E7018 Amperage, to 3/32 E7018 Amperage, every advanced skill grows from these fundamentals.

Quick Note: Right rod, right polarity, chart amps, short arc, slow enough travel.

Frequently Asked Questions

What amperage should I use for a 1/8 inch 7018 rod?

Most welders run a 1/8 in (3.2 mm) E7018 on DCEP between about 110 and 165 amps, starting near 120–130 A for flat butt joints on 1/8 in plate. Adjust by 5–10 A based on bead width: narrow and tall means add current, flat and washed out means back off. Always confirm against the rod manufacturer’s data sheet.

How many amps per 1/16 inch of electrode diameter do I need?

A commonly used starting rule is roughly 1 amp per 0.001 in of rod diameter, so a 1/8 in rod starts near 120 A and a 5/32 in rod near 150–160 A. Treat that as a center point, then fine-tune ±10–15 A for position, joint type and material thickness.

What settings do I need to weld thin sheet metal with a stick welder?

Use a small 1/16 or 3/32 in E6013 rod at roughly 35–55 amps on DC or AC, keep the arc short (about 1/16 in) and weld in short backstep or stitch segments with pre-placed tacks. Reduce arc force/hot start because extra current on thin metal blows through instantly.

Should I weld stick on DCEP or DCEN?

DCEP (electrode positive, also called reverse polarity) is the default for E6010, E6011 and E7018 because it drives heat into the plate for deeper penetration. DCEN (straight polarity) puts more heat into the rod for faster, shallower deposition and is sometimes used with high-deposit rods like E7024; many E6013 rods will run on either, or on AC.

What is the arc force or dig setting on a stick welder?

Arc force momentarily boosts current when the arc gets short, helping the rod keep burning instead of sticking to the work. Use higher dig for cellulose rods like E6010/E6011 and moderate dig for 7018; too much dig on thin steel causes burn-through and excessive spatter.

Why does my electrode keep sticking to the metal?

It is almost always an amperage or technique issue: current too low, arc length too short, a dirty or wet rod, or a poor ground connection. Raise the dial in 5–10 A steps, hold an arc length about equal to the rod diameter, and make sure your ground clamp bites into clean, bare metal.

Do I need to change settings when welding out of position?

Yes. Reduce flat-position current by roughly 10–15% for vertical-up and overhead work, and consider dropping one rod diameter so the puddle freezes faster. Travel speed and work angle also change: overhead needs a very short arc, while vertical-up uses a slight weave or step technique to control the sagging puddle.

Can I weld stainless steel with the same settings as mild steel?

Stainless is usually welded with an E308L-type rod on DCEP at lower heat input than mild steel to control warping and sensitization, since stainless conducts heat poorly. Be aware that stainless welding generates hexavalent chromium fume, covered by OSHA’s 5 µg/m³ PEL under 29 CFR 1910.1026, so ventilation or respiratory protection matters more.

How do I know if my amperage is too high or too low?

Read the bead: too low gives a narrow, tall, rope-like bead with poor side wetting and easy sticking; too high gives a wide flat bead, heavy spatter, undercut at the toes and visible puddle turbulence. Run a bead at your setting, then one 10 A lower and one 10 A higher on scrap — the best profile tells you the answer.

What safety gear is required for stick welding settings practice?

At minimum you need an auto-darkening or fixed-shade helmet (typically shade 10–12 for SMAW), flame-resistant leathers, welding gloves, hearing protection and safety glasses under the helmet. Add local exhaust ventilation or a respirator when welding in confined or poorly ventilated areas, per OSHA’s welding standards.
