How to Stick Weld: Master SMAW Setup, Rods, and Technique

Why do farmers, pipefitters, and repair crews still reach for a stick welder when MIG welding machines and TIG welding machines exist? Because Shielded Metal Arc Welding (SMAW) runs on a simple power source, needs no shielding gas bottle, and works outdoors in wind that would ruin a gas-shielded bead.

The process burns a flux-coated electrode that generates its own shielding as it melts, which is why it handles dirty, rusty, or painted steel that would leave porosity in a MIG weld. That tolerance is the tradeoff: stick sacrifices some speed and appearance for reliability in bad conditions.

That resilience explains why stick remains the field workhorse decades after cleaner processes arrived, especially where portability and forgiving metal prep matter more than a flawless bead.

What Is Stick Welding? Definition, Arc, and Flux Shielding

The coated rod, not a bare wire, is the defining feature of stick welding. Stick welding, one of the core Welding Processes, formally Shielded Metal Arc Welding (SMAW), gets its nickname from the consumable: a straight metal rod, or electrode, coated in a mineral and cellulose flux, gripped in a handheld holder and burned off one "stick" at a time as you weld.

How the Arc and Flux Actually Work

When the electrode tip touches the workpiece and pulls back slightly, electrical current jumps the gap and forms an arc reaching temperatures well over 6,000 degrees Fahrenheit. That heat melts both the base metal and the electrode's core wire, creating a molten puddle. Simultaneously, the flux coating vaporizes, producing a shielding gas that pushes oxygen and nitrogen away from the puddle so the cooling weld doesn't turn brittle or porous, a flux-based shielding principle shared with flux cored arc welding. The leftover flux residue hardens into slag, a glassy crust you chip away once the weld cools.

Key Terms Worth Knowing

• Electrode/rod: the consumable filler metal, sold in specific classifications like E6010 or E7018.
• Puddle: the pool of molten metal where fusion happens.
• Slag: hardened flux covering a finished bead, removed with a chipping hammer and wire brush.
• Amperage: the current setting that controls arc heat and penetration.

Where Stick Welding Gets Used

Because it needs no external shielding gas, unlike MIG Welding, and tolerates wind, rust, and rough conditions, stick welding remains a staple for construction, pipeline work, farm and equipment repair, and structural fabrication where portability matters more than finesse.

What Equipment Do You Need for Stick Welding? AC vs DC, Inverter vs Transformer, and Duty Cycle

A stick welder is a power source that turns wall current into a controlled electrical arc, and the machine you buy determines which electrodes you can run, how long you can weld before it shuts down, and what your shop's wiring needs to support.

AC or DC: Which Current Type Do You Need?

AC (alternating current) output works well with rods like 6011, which are built to handle the current reversing direction and are prized for digging through rust, mill scale, and dirty metal. DC (direct current), especially DC electrode positive, gives a smoother, more stable arc that's easier for beginners to control and is what 7018 low-hydrogen rods prefer. A DC-only inverter covers the majority of beginner work. AC/DC machines add flexibility for pipeline-style rods or magnetic arc blow situations, but that capability is a step beyond what most new welders need on day one.

Transformer vs Inverter

Traditional transformer machines, like the Lincoln AC-225 rated at 225A and 20% duty cycle¹, are heavy, simple, and durable, but they're bulky and less efficient. Inverter machines use electronic circuitry to shrink the transformer, cutting weight dramatically while improving arc control and energy efficiency. Inverters cost a bit more up front but dominate the beginner and hobbyist market today because they're portable and often dual-voltage.

Understanding Duty Cycle

Duty cycle is the number of minutes out of a 10-minute period a machine can weld at a given amperage before it needs to cool. A 160A-class inverter might weld 65A at 120V for 20% duty cycle, roughly 2 minutes on, 8 off, or 160A at 240V for 30%.¹ That's plenty for home projects and hobby fabrication, but far short of what a production shop running all day requires.

Power Requirements and What to Buy

Small 120V machines typically need an 18-20A input on a 20A breaker with 12 AWG wire.² Stepping up to 240V, common for sustained welding and thicker material, usually means a dedicated 40-50A circuit.² A licensed electrician should confirm sizing against the nameplate and local code before installation.

For most beginners, a 160-200A DC inverter with dual-voltage input hits the sweet spot: light enough to carry, capable of running 7018 and 6011, and flexible enough to plug into a garage outlet or a proper 240V circuit as skills grow.

What Does Stick Welding Cost in 2026? A Beginner's Budget Breakdown

A beginner stick welding setup is often cheaper than people expect, but the total depends on machine choice, protective gear, and consumables. The table below shows typical 2026 price ranges collected from Amazon, Home Depot, and welding supply retailers. Use these ranges as a starting point and check current listings before buying.

7018 Electrode Storage: How to Prevent Hydrogen Cracking and Porosity

E7018 earns the "low-hydrogen" label because its flux coating is formulated to keep diffusible hydrogen out of the weld metal. That matters because hydrogen atoms trapped in a cooling weld migrate to grain boundaries and cause hydrogen-induced cracking (sometimes called delayed or underbead cracking), a defect that can appear hours or days after welding. The catch is that the flux is hygroscopic: it pulls moisture out of humid air, and that water breaks down in the arc to release the very hydrogen the electrode is supposed to exclude. Moisture also produces surface porosity, a rougher arc, and brittle, crack-prone welds.

Storage Temperatures and Exposure Limits

Once a hermetically sealed can is opened, unused 7018 rods should be transferred to a holding oven at 250 to 300 °F, per AWS A5.1 guidance and manufacturers like Hobart and Lincoln Electric.¹ Heated storage cabinets at the point of use typically run cooler, around 100 to 120 °F, and are meant for short-term staging, not primary storage.³ Rods from a freshly opened sealed can generally do not need pre-use baking if they go straight into the holding oven.

Exposure time out of the oven depends on the electrode's hydrogen designation, ambient humidity, and the governing code or WPS. Common ranges cited in AWS-related guidance: E7018-H4 or H4R around 4 hours (often at 50% relative humidity or below), non-H-suffix E7018 up to about 9 hours in mild conditions, and some code applications tightening non-R H4 to 1 to 2 hours.⁴⁵ Always defer to the manufacturer's data sheet and your WPS.

Spotting Moisture Damage and Reconditioning

Suspect moisture pickup if you see surface porosity or "worm tracks," a spitty arc, a chalky or discolored flux, or coating that flakes off the rod. If rods have exceeded their allowed exposure, reconditioning per AWS A5.1 and Hobart is 500 to 800 °F for 1 to 2 hours; some guidance narrows moisture-soaked 7018 to roughly 700 to 800 °F for 1 hour.¹⁶ Do not toss cold rods into a hot oven, because thermal shock can crack the coating.

Home-Shop Options

Small benchtop rod ovens from welding suppliers hold 250 to 300 °F reliably and are the right tool. Vacuum-sealed containers with fresh desiccant can extend life of unopened or lightly used rods, but they are not a substitute for heated storage on active jobs. Never bake 7018 in a kitchen oven: flux fumes are not food-safe, temperature control is unreliable, and contamination runs both directions.

How Do You Set up a Stick Welder? Polarity, Amperage, and Ground Placement

A good stick weld starts before the arc: match the machine to the electrode, put the ground where it belongs, and finish with a deliberate safety pass. These four setup steps apply to transformer and inverter machines alike.

Stick Welding Safety: Ventilation, Electric Shock, and Fire Prevention

Stick welding produces fumes and electrical hazards that will hurt you long before a bad bead does, and OSHA's rules under 29 CFR 1910.252, 1910.134, and 1910.133 exist because both risks are preventable with the right Welder Safety habits.¹

Ventilation and Fume Exposure

SMAW fumes contain contaminants regulated individually rather than under one blanket limit. Hexavalent chromium, common in stainless and some coated electrodes, carries an 8-hour exposure limit of just 5 micrograms per cubic meter, low enough that casual airflow rarely covers it.² As a practical benchmark, mechanical ventilation delivering roughly 2,000 CFM per welder is generally expected once natural airflow can't keep pace, and it's typically required in shops under 10,000 cubic feet of space per welder or with ceilings under 16 feet, unless you're using local exhaust hoods, a fume extraction booth, or a supplied-air respirator.³ Natural ventilation may be acceptable in larger, higher-ceilinged shops with genuine cross-ventilation, but confined spaces almost always require mechanical help.³ If you rely on a respirator instead of ventilation, OSHA requires a written respiratory protection program and an annual fit test, not just a dust mask off the shelf.²

Electric Shock and Fire Prevention

Stick welders run open-circuit voltage high enough to shock through wet gloves, damaged holders, or bare-handed electrode changes. Keep your gloves and clothing dry, inspect cables and the electrode holder for cracked insulation before every session, and confirm your ground clamp has solid metal-to-metal contact. ANSI Z49.1 now calls for wet-floor protection unless you're welding on wood laid directly over concrete.⁵

Fire risk persists after you stop welding. Clear combustibles from a 35-foot radius⁴, keep an extinguisher within reach, and post a fire watch for at least 30 minutes after you stop welding¹ whenever slag or sparks could have reached hidden material.

Required PPE

Wear a helmet shaded #10 for typical amperages (higher for heavier currents), safety glasses underneath it, leather gloves, and long sleeves with no exposed skin.²

How Do You Strike and Maintain an Arc? Arc Starting, Length, Travel Angle, and Drag Technique

Starting the Arc: Tap or Scratch

Two methods get the arc going, and most welders use both depending on the rod.

• Tapping: Bring the electrode straight down onto the joint, touch the plate, and lift about an eighth of an inch immediately. This method places the arc exactly where you want it, which matters when you are restarting in a groove or at the toe of a previous bead.
• Scratching: Drag the electrode across the plate like striking a match, then lift. Scratching is more forgiving for beginners and works well with 7018, which has a harder-to-start flux coating.

If the rod sticks, twist it sharply side to side to break it free. If it welds itself solid, flip the machine off before prying it loose. Sticky rods usually mean amperage is too low or you hesitated on the lift. Bump the amps up ten and lift faster.

Arc Length and Travel Angle

Hold an arc roughly equal to the diameter of the electrode core wire. With a 1/8 inch rod, that is about 1/8 inch of gap. Too long and the arc wanders, spatter scatters across the plate, shielding gas from the flux disperses, and porosity shows up in the bead. Too short and the rod freezes or the arc sputters out. Listen for a steady crackle like frying bacon.

For most electrodes in flat and horizontal work, tilt the rod 10 to 15 degrees in the direction of travel, a drag angle. You are pulling the electrode toward you while the arc force pushes slag behind the puddle. For vertical up progression, hold the electrode close to perpendicular to the plate, sometimes with a slight upward tilt, so the puddle does not sag.

Drag Versus Manipulation

On flat and horizontal joints with 7018, a straight drag with minimal weaving produces the cleanest bead. Keep the travel speed consistent and let the puddle trail about a rod width behind the arc.

Vertical and overhead work demands manipulation. A small circular or triangular motion lets the puddle freeze briefly at the edges, building the bead without letting it run. With fast-freeze rods like 6010 and 6011, the whip technique (moving the arc forward out of the puddle, then back in) gives the metal a moment to solidify before you add the next bit of filler.

What Are the Basic Stick Welding Positions? Flat, Horizontal, Vertical, and Overhead

The American Welding Society designates four core test positions, 1G, 2G, 3G, and 4G, and each one demands a different work angle, travel angle, and electrode manipulation.

Flat and Horizontal (1G and 2G)

1G is flat position welding, plate or pipe lying horizontal with the weld face up, and it is the easiest place to learn puddle control. Hold the electrode at a 45 degree work angle to the joint and let gravity help the puddle settle. 2G is horizontal position, typically a vertical plate with the weld axis running horizontal. Here the work angle shifts to 45 to 60 degrees, angled slightly upward, to keep the molten pool from sagging down the face before it solidifies.

Vertical (3G)

3G means welding vertically, and most beginners run it vertical up rather than vertical down for structural work because vertical up produces deeper penetration and better fusion. Travel angle drops to 10 to 15 degrees, dragging the rod slightly uphill, and with 7018 electrodes a slight weave (crescent, zigzag, or box pattern) controls heat buildup and bridges gaps that a straight stringer bead would undercut. Pause at each side of the weave just long enough to wash into the sidewall without blowing through.

Overhead (4G)

Overhead position is the most physically demanding and the one where gravity works against you the hardest. A short, tight arc length is essential: too long an arc lets the puddle sag and drop, while a short arc lets surface tension hold the weld metal in place until it freezes. Smaller electrode diameters and slightly lower amperage than flat position help keep the puddle manageable overhead.

Why Position Matters for Certification

Employers and testing facilities certify welders by position because each one carries genuinely different skill requirements. If you are working toward structural or pipeline credentials, the 3G welding certification and 4G welding certification guides walk through the specific bend test and visual inspection criteria examiners look for, and the 6G pipe welding guide covers the 45 degree fixed pipe test that combines all four positions into a single continuous weld.

How Do You Prepare Joints and Avoid Common Stick Welding Defects?

Specific causes and corrections for porosity, slag inclusion, undercut, lack of fusion, and arc blow vary by electrode, position, and machine. Instead of a one-size-fits-all list, use this table to find the most common SMAW defects and the authoritative sources to consult for your exact setup. Cross-check any adjustment against your electrode's operating data sheet and test on scrap before production.

How Does Stick Welding Compare to MIG and TIG?

Stick welding remains the field workhorse while MIG welding dominates production shops and TIG welding owns code-quality root passes¹, and that division of labor shows up in real utilization numbers, not just tradition.

Government wage and employment statistics don't actually break welders out by process. The federal occupational code covering welders lumps stick, MIG, and TIG operators into a single category², so any claim about a "stick welder salary" versus a "MIG welder salary" is an inference, not a published figure. What the data does support is that structural, pipeline, and boiler work, where stick still leads, tends to sit in the upper half of the general welding wage range, while high-volume MIG production work clusters nearer the middle.

What the Shop Floor Actually Shows

Two industrial case studies illustrate how differently shops lean on each process. At one shipyard, stick welding accounted for roughly 68 percent of arc welding performed, with TIG at about 14 percent and MIG under 13 percent³, a split driven by field access, wind exposure, and the need for weldable-anywhere flexibility. At a pressure-vessel fabricator, the mix flipped almost entirely: MIG and submerged arc covered roughly 53 percent of work, TIG handled about 27 percent for code-quality joints, and stick dropped to under 18 percent³. Neither number should be read as a national average. They're two facilities, and your local shop may look nothing like either.

Productivity and Training Order

Comparative welding studies consistently rank semi-automatic MIG as more productive per hour than manual stick or TIG, since wire feed eliminates rod changes and slag chipping. That's a real efficiency gap, but productivity isn't the only metric employers weigh. Portability, out-of-position performance, and tolerance for wind and mill scale keep stick welding relevant on job sites where a generator and a rod oven are the only equipment options.

Most training programs still teach stick first, then MIG, then TIG¹, treating SMAW as the foundation that builds arc control and puddle reading before students move to faster or more delicate processes. That sequencing is pedagogical, not a reflection of which process pays more or gets hired more often, so treat any hard salary comparison you see online with the same skepticism you'd apply to a shop's unverified welding jobs posting.

Frequently Asked Questions About Stick Welding

These answers cover the practical questions welders ask most when starting with stick welding, one of several types of welding. Each response reflects common industry guidance rather than one-size-fits-all rules, so always check your electrode datasheet and project code.

What is the difference between 6010 and 7018 welding rods?

Both are all-position rods, but 6010 has a high-cellulose, sodium coating and a minimum tensile strength of 60,000 psi. It runs on DCEP and produces a thin, fast-freezing slag that suits root passes and open-root pipe. 7018 has a low-hydrogen, iron-powder coating and a 70,000 psi minimum tensile strength. It runs on DCEP or AC, produces a heavier slag, and is common for structural steel and critical code work.

Can you stick weld aluminum?

Yes, but it is not recommended for beginners.¹ You need aluminum-specific flux-coated electrodes, such as E4043, made under AWS A5.3/A5.3M-2023.² Welding aluminum with stick is generally harder than steel, and MIG Welding Aluminum is another process; use DCEP or AC as the rod datasheet says, keep a short arc, clean the oxide layer, and travel faster than you would on steel. Exact amperage varies by alloy and rod diameter, so test with the manufacturer's settings.

What causes porosity in stick welding?

Porosity often comes from moisture or surface contamination such as oil, grease, paint, or rust.³ Moisture-sensitive electrodes like 7018 can cause porosity if stored improperly or not rebaked per the maker's instructions. Holding too long an arc length weakens shielding and can also pull air into the weld. Check electrode class, storage, polarity, amperage, arc length, and technique before assuming one cause.

What is the best stick welder for a beginner?

There is no single best model, but a beginner-friendly machine should have stable DC output, a useful range for small electrodes, hot-start and arc-force controls, anti-stick, enough duty cycle for your typical work, and thermal protection. If you plan to run 6010, confirm the machine supports DCEP. Many entry-level machines handle 6011 on AC, so match the unit to your electrode and input power.

How do you prevent slag inclusions?

Clean slag fully between passes, use the correct travel angle, and avoid excessive downhill travel.³ Low amperage can leave slag trapped at the toes and sidewalls, so set current high enough for the electrode and joint. Keep a proper arc length, especially with 7018, because an overly short arc can entrap slag. Follow your procedure and clean the joint before each pass.
