Lincoln Electric Stick Welding Guide

Stick welding — Shielded Metal Arc Welding (SMAW) — is the backbone of construction, pipeline, farm repair, and structural fabrication. It's simple to set up, works on dirty or rusty metal, needs no external shielding gas, and runs reliably in wind and rain. Lincoln Electric has been manufacturing stick welding equipment for over a century, and that history shows in the arc characteristics of machines like the AC-225 and Invertec series. Whether you're a hobbyist fixing equipment on the farm or a certified welder laying root passes on pipe, the right Lincoln setup makes the difference. Browse our full selection of Stick Welders and Stick Welding Rods to build your kit.

What is Stick Welding (SMAW)?

Stick welding works by striking an electric arc between a flux-coated consumable electrode (the "stick") and the base metal. The arc generates intense heat — around 6,500°F — that melts both the electrode tip and the surrounding base metal into a shared weld pool. As the electrode burns, the flux coating does two critical jobs simultaneously: it combusts to produce a shielding gas that keeps atmospheric oxygen and nitrogen out of the weld pool, and it forms a slag layer on top of the cooling bead that slows oxidation as the metal solidifies. Once the bead cools, you chip the slag away to reveal the finished weld.

AC vs. DC: Most Lincoln machines output DC (direct current), which provides a smoother, more stable arc than AC. DC+ (electrode positive, or DCEP) drives more heat into the electrode for deeper penetration — ideal for 6010 and 7018 rods. DC− (electrode negative, or DCEN) puts more heat into the base metal for faster travel speeds and shallower penetration, used with certain 6013 and 7014 applications. AC power, still found in transformer machines like the Lincoln AC-225 (K1170), works fine with AC-rated rods like 6011 and handles certain rusty or magnetized steel situations where DC arc blow is a problem.

Why stick welding still dominates field work:

• No gas bottle required — works anywhere there's power (or a generator)
• Tolerates mill scale, rust, and surface contaminants better than MIG or TIG
• Welds carbon steel, stainless, cast iron, and low-alloy steel with the right rod
• Penetrates thick sections (3/16" and up) that thin-wire MIG struggles with
• Wind and outdoor conditions that would blow out a MIG shielding cone don't affect SMAW

Stick Welding Electrode Guide

Choosing the right rod is just as important as choosing the right machine. The AWS classification system tells you exactly what you're buying: in a number like E7018, the "E" means electrode, "70" means 70,000 psi minimum tensile strength, "1" means all-position capable, and "8" describes the flux coating and recommended polarity. Here's a breakdown of the five rods you'll encounter most often:

Reading the rods in detail:

E6010 — Lincoln Fleetweld 5P+: The pipeline welder's go-to. Cellulosic coating burns hot and fast with a deeply penetrating, fast-freeze arc that lets you weld open-root joints in any position. Requires DC+ and a machine with enough open-circuit voltage (OCV) — look for 70V+ OCV. Available in multiple sizes from WeldingMart (ED032565 in 1/8", ED032564 in 3/32").

E6011: Essentially 6010's AC-compatible cousin. Useful on AC transformer machines or when the base metal is galvanized, painted, or magnetized. Lincoln's Fleetweld 180 runs on AC or DC+.

E6013: Low-penetration rod with a soft, forgiving arc. The flux produces a fluid slag that's easy to control for cosmetic welds on thin material. Runs AC or DC on almost any machine. Lincoln's Fleetweld 37 (ED028153 for Fleetweld 35, a close variant) is a shop staple.

E7014: Iron-powder coating boosts deposition rate significantly. Good for flat and horizontal fillet welds where speed matters more than deep penetration. Runs AC or DC on most machines.

E7018 — Lincoln Excalibur 7018 MR: The structural welder's workhorse. Low-hydrogen flux coating keeps hydrogen content under 8 mL/100g, which is critical for preventing cold cracking in high-strength or restrained joints. The "MR" designation means moisture-resistant coating — you get more working time out of an open can without baking. Available in 3/32", 1/8", and 5/32" from WeldingMart (ED032589, ED028282). For maximum low-hydrogen performance, Lincoln's Excalibur 7018 XMR (ED037426) pushes moisture resistance even further.

Store low-hydrogen rods (7018) in a Lincoln HydroGuard rod canister (K3166-1) once the package is open. Exposed 7018 absorbs atmospheric moisture quickly, which reintroduces hydrogen into your welds.

Choosing a Lincoln Electric Stick Welder

Lincoln builds stick welders across a wide range of duty requirements. Here's how to match machine to application:

Farm / DIY repair — Lincoln AC-225 (K1170): The AC-225 has been in production for decades for good reason. It's a pure transformer machine — no circuit boards to fail, no electronics to troubleshoot. Plug it into a 230V outlet, set the amperage dial, and weld. It runs 6011 and 6013 rods all day at amperages suitable for 1/4" to 1/2" steel. At around $780, it's the lowest cost of entry for serious stick welding. The AC/DC 225/125 (K1297) adds a DC rectifier, unlocking 7018 capability.

Dual-process / learning — Power MIG 215 MPi (K4876-1): If you're just getting into welding or want one machine that handles MIG, flux-core, stick, and DC TIG, the 215 MPi covers all four processes. It runs on 120V or 230V (dual-voltage), which means it moves between the garage and the shop without an adapter hassle. Stick performance is solid up through 3/16" steel. Not the tool for heavy structural work, but ideal for the welder building skills across processes.

Pipeline / field construction — Lincoln Ranger 225 (K2857-1): When there's no grid power on a jobsite, you need an engine drive. The Ranger 225 runs on a Kohler gasoline engine and outputs up to 225A of stick welding current with no utility hookup required. It also generates AC power for tools and lighting. For higher-amperage pipeline work, the Ranger 250 GXT (K2382-4) and Frontier 400X Pipe (K3485-2) step up the output ceiling. See the full Engine Driven Welders catalog.

Industrial fabrication — Idealarc 250 (K1053-8): When a production shop needs a machine that runs 8–10 hours a day without complaint, the Idealarc 250 delivers. It's a heavy-duty transformer/rectifier unit rated for 100% duty cycle at lower amperages. Three-phase input keeps operating costs down. At 250A output, it handles 3/16" and 1/4" electrodes for heavy plate and structural work.

Advanced DC stick / multi-operator — Invertec V276 (K4868-1/K4868-2): The Invertec V276 is Lincoln's premium DC stick and TIG inverter. At 276A output with a wide input voltage range (208–575V), it runs everywhere. The 4-pack rack (K4869-1) and 8-pack rack (K4869-2) let industrial shops run multiple welding stations from a single bank of inverters. Ideal for fabrication shops running 7018 and 7016 on structural code work.

Essential Stick Welding Accessories

The machine and rod get the attention, but the accessories between them determine whether you have a clean, stable arc or a frustrating session of sticking and spatter.

Electrode Holders: Match your holder to your machine's output. Lincoln's industrial holders are color-coded by amperage: the K5154-1 handles up to 200A (1/8" and 3/32" rods), the K5155-1 covers up to 250A (for 5/32" and larger), and the K5156-1 goes to 300A for heavy-plate work with 3/16" rods. Undersizing your holder heats the jaws and degrades arc quality — don't use a 200A holder on a 250A machine running all day.

Ground Clamps: The Lincoln GC-300 (K910-1) is a 300A work clamp rated for 60% duty cycle — appropriate for most shop and farm setups. Make sure your ground clamp is clamped directly to the workpiece, not to a table leg or vise with paint between connections. A poor ground is the #1 cause of erratic arc behavior.

Welding Cable: For runs up to 100 feet at 150A or less, 2 AWG cable is adequate. For machines running 250A or more, step up to 1/0 cable. Undersized cable creates voltage drop that kills arc performance and overheats the lead.

Rod Storage: Low-hydrogen rods (7018, 7016) must be kept dry. Lincoln's HydroGuard rod canister (K3166-1) keeps opened containers sealed from humidity. For production environments, a dedicated rod oven (Lincoln's Phoenix or similar) bakes moisture out of rods that have been exposed.

Chipping Tools: You'll need a chipping hammer after every pass. The Lincoln Radius Chipping Hammer (K4022-1) and the Chipping Hammer & Wire Brush Combo (K4021-1) cover most situations. The cone point breaks slag on flat beads; the chisel tip cleans corners and fillet welds.

Stick Welding FAQs

What metals can be welded using stick welding?

SMAW works on carbon steel, low-alloy steel, stainless steel, cast iron, and some nickel alloys. With the correct electrode — stainless rods for stainless, nickel-based rods for cast iron — you can weld dissimilar metals in repair situations. Aluminum is not suitable for stick welding; use MIG or TIG for aluminum.

Can stick welding be used outdoors?

Yes — it's one of the reasons SMAW dominates pipeline and construction work. The flux coating generates its own shielding atmosphere, so wind that would blow out a MIG shielding cone doesn't stop a stick welder. Run 6010 or 6011 in conditions where MIG simply won't work.

Is stick welding good for beginners?

Equipment setup is simple: clamp the ground, strike an arc, and maintain travel angle and speed. The hard part is developing the hand coordination to maintain consistent arc length as the electrode burns down. Most beginners should start with 6013 on DC — it has the most forgiving arc and easiest slag removal of any common rod.

What are common stick welding electrodes?

6010, 6011, 6013, 7014, and 7018 cover 95% of stick welding applications. Lincoln's Fleetweld and Excalibur product lines are among the most widely used and tested electrodes available.

What are the advantages of stick welding?

No shielding gas bottle to haul around, works on coated or contaminated metal, handles thick sections, works outdoors and in the field, and equipment is relatively low cost compared to TIG or pulse MIG setups. It's also the most portable process — pair a Lincoln inverter with a generator and you can weld anywhere.

What amperage should I use for 1/8" 7018?

For 1/8" (0.125") E7018, the standard starting range is 110–140A on DC+. Start at 115A and adjust based on puddle behavior: if the slag is getting ahead of the arc or the bead is too tall and ropey, increase amperage. If you're getting undercut or the puddle is too fluid to control in position, back down. Vertical-up welds typically run 10–15% lower than flat position.

How do I strike an arc without the electrode sticking?

Use a scratch or tap start. For scratch start: drag the electrode tip across the base metal at a shallow angle, then quickly lift to establish arc length (roughly equal to the electrode diameter). For tap start: touch and lift quickly. If the electrode sticks immediately and won't release, quickly bend it side-to-side rather than pulling straight back — that usually breaks the weld nugget at the tip. If the machine has Hot Start control (like Lincoln's Invertec series), use it — it briefly boosts OCV to prevent sticking during arc initiation.

Why does my electrode keep sticking to the metal?

The most common causes: amperage is set too low for the rod diameter, arc length is too short (you're burying the electrode in the puddle), or the rod is the wrong type for your machine (e.g., running 7018 on a low-OCV machine that can't maintain the arc). Check that your polarity is correct for the rod you're using. Also verify your ground connection is solid — a high-resistance ground drops effective welding voltage and causes sticking.

How do I read an electrode classification number?

Using E7018-H4R as an example:

• E = electrode
• 70 = minimum tensile strength, 70,000 psi
• 1 = all-position (flat, horizontal, vertical, overhead); "2" means flat and horizontal only
• 8 = flux type and usable current (low-hydrogen, DC+/AC)
• -H4R = optional suffix: H4 means ≤4 mL/100g diffusible hydrogen; R means moisture-resistant coating

What's the difference between DC+ (DCEP) and DC− (DCEN) polarity?

In DC+ (electrode positive / DCEP), the electrode is the positive terminal and roughly two-thirds of the arc heat concentrates at the electrode. This gives deeper penetration into the base metal and is required for 6010 and 7018. In DC− (electrode negative / DCEN), more heat goes into the base metal side — which seems counterintuitive but results in faster melt-off of the electrode, higher deposition rates, and shallower penetration. Some 6013 and 7014 applications use DCEN for speed on thin material. Check the electrode manufacturer's data sheet to confirm the recommended polarity.
