3/32 E7018 Amperage: Settings, Polarity & How to Run It
My first E7018 rod went about as badly as a weld can go without catching fire. I was…
READ ARTICLE →You bought your first stick welder, struck an arc, and within two seconds the rod welded itself to the plate. You yank it loose, try again, and get a sputtering, spattery mess that looks nothing like the smooth beads in the videos. So you figure the machine is junk, or you just don’t have the hands for it.
Here’s the good news: the machine is probably fine, and so are your hands. The real problem is the rod in the stinger.
Shielded metal arc welding (SMAW), better known as stick welding, uses a covered electrode that supplies both the flux shield and the filler metal, as OSHA notes in its welding fume fact sheet. That coating does more than look pretty. As the arc burns, it creates shielding gas, forms slag to protect the cooling weld, and helps stabilize the arc itself. Choose a rod that suits your machine and your metal, and all three jobs get easier. Choose the wrong one, and every single one gets harder.
Stick remains the most popular entry point for hobbyists for good reasons. The equipment is cheap, the process is versatile, and it works outdoors in wind that would blow a shielding gas cloud apart. One machine, a stinger, a ground clamp, and a box of rods is enough to start joining metal. It also happily welds rustier, dirtier steel than fussier processes tolerate.
That simplicity is exactly why electrode choice matters so much. Newcomers who cut their teeth on a wire feeder spend their energy chasing wire speed and voltage; if that’s your path, our complete beginner’s guide to using a wire welder covers that side. On a stick machine, though, the electrode is the single biggest variable you actually control. Get it right and the learning curve flattens fast.
When welders say “rod,” they almost always mean a coated stick electrode, not bare filler wire. The American Welding Society sorts carbon steel electrodes under the AWS A5.1/A5.1M specification, which governs their mechanical properties and usability. There are hundreds of classified electrodes, which sounds terrifying, but beginners genuinely need only a handful.
Quick Note: A beginner rod is not the same as a structural rod. The label hides a full code, and reading it is the fastest skill upgrade you can make this week.
Over the next sections we’ll decode the label codes like E6013 and E7018, compare the big four beginner rods side by side, and match the right electrode to your machine’s polarity and voltage. You’ll get an amperage and rod-size cheat sheet, fixes for the ten mistakes almost every beginner makes, and a straight answer on why E7018 needs dry storage while E6013 does not. Most newcomers run 3/32 in (2.4 mm), 1/8 in (3.2 mm), or 5/32 in (4.0 mm) diameters, so we’ll cover those too, along with safety, buying advice, and a practice roadmap that pairs well with our guide to building real welding skills.
The bottom line: the right rod, matched to your machine and material, turns stick welding from a fight into a skill. Let’s find yours.
The label on a stick electrode looks like a random string of numbers. It is not. Every character is defined by AWS A5.1/A5.1M, the specification for carbon steel electrodes for shielded metal arc welding. Learn to read the code left to right and you can predict how a rod runs before you strike an arc.
The leading E simply stands for electrode, and every SMAW rod wears it. That is the one part of the code you never have to guess about. Because the system is standardized, a rod from any brand can be compared apples to apples.
The next two digits give the minimum tensile strength in thousands of pounds per square inch (ksi). An E60xx rod deposits weld metal rated at 60,000 psi; an E70xx is rated at 70,000 psi. As MillerWelds puts it, in E7018 the “70” means a minimum tensile strength of 70,000 psi.
The third digit is about where you can weld. Per the AWS A5.1 classification, “1” means all position (flat, horizontal, vertical, and overhead), while “2” means flat and horizontal only. That single digit is why E6013 is a great first rod and E7024 is a production flat-position rod.
The final digit describes the flux coating and the current the rod wants. This is the beginner’s cheat code because it answers two practical questions at once: which polarity do I set, and does this rod need special storage? Different coating families behave very differently:
| Rod | Tensile | Position | Coating & Current |
|---|---|---|---|
| E6010 | 60 ksi | All | High-cellulose sodium / DC only |
| E6011 | 60 ksi | All | High-cellulose potassium / AC or DC |
| E6013 | 60 ksi | All | Rutile / AC or DC |
| E7018 | 70 ksi | All | Iron powder low-hydrogen / AC or DCEP |
Not sure what DCEP and DCEN mean? DCEP is electrode positive (also called reverse polarity), and DCEN is electrode negative (straight polarity). If you come from wire welding, the same labels show up in our guide to polarity for flux core welding, where DCEN and DCEP flip the heat between the wire and the plate.
Quick Note: If you remember only one thing, remember the last digit. It tells you the polarity and whether the rod is low-hydrogen and storage-sensitive.
Take E6013. The E is electrode, 60 is 60,000 psi tensile, 1 is all position, and 3 is a rutile coating that runs on AC or DC. Now E7018. The E is electrode, 70 is 70,000 psi, 1 is all position, and 8 is an iron powder low-hydrogen coating run on AC or DCEP. Harris Products Group defines E7018 as an all-position iron powder, low-hydrogen electrode that yields x-ray quality welds.
Extra letters and numbers after the core code carry more detail. A -1 suffix (like E7018-1) signals improved notch toughness for low-temperature service. H4R is a low-hydrogen marker: H4 caps diffusible hydrogen at 4 mL per 100 g of weld metal, and R means a moisture-resistant coating. That is why a package of E7018 left open in a damp shop can run badly even though the label has not changed. The 15/16/18 trio all share the basic low-hydrogen coating but split by current: E7015 is DCEP only, E7016 runs on AC or DCEP, and E7018 adds iron powder for higher deposition on AC or DCEP.
Reading the label is step one; running the rod is step two. Build that skill deliberately with a structured plan from our guide to welding practice.
Walk into any welding supply shop and you’ll see dozens of stick electrodes. Ignore most of them for now. As a beginner, four rods cover almost everything you need to get started: E6013, E6011, E6010, and E7018. They look similar on the shelf, but they behave very differently under the arc. Pick the wrong one and you’ll fight the rod all afternoon.
For clean, thin sheet metal or light general repair, E6013 is the rod to reach for first. It lays down a soft arc with minimal spatter, produces moderate penetration, and leaves slag that peels off easily once it cools. That forgiving nature is why so many entry-level machines ship with a starter pack of 6013. It also restrikes without drama, so you won’t be scraping the tip.
The trade-off is penetration. E6013 sits shallow, which is great for sheet metal but not ideal for thick plate or dirty steel. Use it on clean material in the flat and horizontal positions and you’ll get tidy, presentable beads fast. Per MillerWelds, it’s the “easy to use” electrode that suits thin material best.
E6011 is the rod you grab when the metal is rusty, painted, or greasy and you don’t have time to grind. It runs on either AC or DC, so it works on cheap buzz-box welders that only offer AC. The arc digs hard, cutting through surface contamination that would make a 6013 sputter.
That makes 6011 a maintenance and repair favorite. If you’re fixing a trailer, a gate, or farm equipment where you can’t get a perfectly clean surface, this is the rod. The deep-digging arc leaves a rougher bead and more spatter than 6013, so it’s less pretty, but it bites into the base metal and holds.
E6010 shares 6011’s aggressive digging character but demands DC. It’s famous as the pipe-root electrode because it delivers deep penetration and burns through the bevel cleanly. The catch is the arc. It’s extremely tight, meaning the rod has to stay almost touching the workpiece, and that sensitivity makes 6010 genuinely difficult for novices. Lose your arc length for half a second and the rod sticks or the weld goes porous.
Respect it, learn it later. E6010 is a skill-building rod, not a first choice.
E7018 is a low-hydrogen electrode with a thick high-powder flux. It runs smoothly, welds thick structural steel, and provides strong low-temperature impact properties once deposited. It’s also the easiest of the four to run once you’ve learned to weld at all, because the arc is stable and the bead stacks neatly in all positions, from flat to overhead.
The catch is moisture. Because it’s low-hydrogen, E7018 must stay dry. Leave it out overnight in a humid shop and it can absorb moisture that promotes porosity and cracking. Keep it sealed or in a rod oven. The reward is a strong, clean, professional-looking weld, which is exactly why structural work leans on it.
Quick Note: “Low-hydrogen” refers to the flux coating, not the steel you’re welding. When 7018 picks up moisture, hydrogen enters the arc and can leave porosity and under-bead cracking. Dry rod, sound weld.
| Rod | Current | Penetration | Best For | Beginner Difficulty |
|---|---|---|---|---|
| E6013 | AC or DC | Shallow/moderate | Sheet metal, clean general repair | Easiest |
| E6011 | AC or DC | Deep | Rusty, dirty, painted steel; maintenance | Easy–moderate |
| E6010 | DC only | Very deep | Pipe roots, code work | Hard |
| E7018 | AC or DC | Medium/deep | Structural steel, all-position strength | Moderate (needs dry storage) |
Mechanical strength differs too. Under AWS A5.1, E6013 delivers roughly 67 ksi tensile strength while E7018 reaches about 72 ksi, with elongation of 17 to 22 percent. In plain terms, 7018 makes a stronger, more ductile joint, which matters for anything load-bearing.
Start with a small pack of 3/32-inch E6013 for learning and clean practice, plus a pack of 3/32-inch E6011 if you plan on repairing dirty metal or only have an AC machine. Add E7018 once your beads are consistent and you want strong, structural-quality welds. Before you dial in the machine, it’s worth understanding how amperage, polarity, and rod size interact, so the 3/16 E7018 amperage guide is a useful reference as you scale up. And if you’re wondering whether a wire-feed setup suits you better, our breakdown of whether flux core is the same as MIG clears that up.
Buy 6013 and 6011 now, learn your arc, then graduate to 7018. Save 6010 for when you’ve got real control.
Picking a rod is only half the decision. The other half is whether your machine can actually feed it the right current. Every electrode’s flux coating is engineered for a specific current type and polarity, so your welder’s capabilities narrow the menu before you ever strike an arc. Choose a rod your machine can’t run properly and you’ll fight sticking, sputtering, and weak beads all afternoon. The good news is that once you understand a few basic rules, matching rods to machines becomes second nature.
The coating isn’t just a shield against the atmosphere. It stabilizes the arc and helps control where heat concentrates. That’s why each AWS classification lists approved current types and polarities. Run a rod outside that spec and the arc turns erratic or the slag won’t release cleanly. The current requirement comes from the coating chemistry, not the steel core. Think of the coating as the rod’s instruction manual, telling you how it wants to be run.
| Electrode | Runs On | Not Recommended |
|---|---|---|
| E6013 | AC, DCEP, or DCEN | — |
| E6011 | AC or DCEP | DCEN |
| E6010 | DC only (DCEP) | AC |
| E7018 | AC or DCEP | DCEN |
Polarity decides which side of the arc absorbs more heat. With electrode positive (DCEP), electrons bombard the workpiece, so more heat lands in the metal. That means deeper penetration and a wider fusion zone. With electrode negative (DCEN), the balance flips: heat concentrates in the rod, which melts faster but bites into the plate less. This is the same physics that governs every arc process, and if you want the fuller explanation it’s worth reading TIG Welding Polarity: DCEN, DCEP, and AC Explained for Precision Welds.
AC alternates between these two states many times per second. It splits the difference, giving decent penetration while easing arc blow and helping with magnetic issues. That versatility is why AC-only welders still get plenty done. Tune your settings to the polarity the rod calls for and the arc rewards you with smoother, more consistent results.
Here’s where machine specs collide with rod choice. E6010 is limited to DC power sources, while E6011 can run on AC, making 6011 the practical choice when only AC is available, as MillerWelds explains. Both are cellulosic rods with a forceful, digging arc.
E7018 operates on AC or DCEP and is not run on DCEN. Its low-hydrogen iron-powder coating needs that polarity to deposit smoothly and keep hydrogen out of the weld. E6013 is the friendly outlier: it runs on AC or either DC polarity, which is exactly why it’s the go-to starter rod.
DC output also gives you a choice of polarity, while budget AC machines simply don’t. If steel is your focus and you want to understand current choice more broadly, see AC or DC for TIG Welding Steel? The Complete Answer. Beginners on a tight budget should pick rods to match the machine they own, not the other way around.
Many inexpensive AC welders have a low open-circuit voltage (OCV), often in the 45–50 volt range. Cellulosic electrodes like E6010 need a higher voltage to establish and sustain their arc. On a low-OCV machine, the arc extinguishes almost as soon as it starts, and you spend the session re-striking instead of welding. E6011’s AC-friendly formulation helps, but a truly weak machine may still struggle.
This is where E6013 shines. Its rutile coating strikes easily, restarts readily, and tolerates the modest output of a hobby welder. On a limited machine, the “best” rod is the one the machine can hold an arc with. That said, an experienced hand can sometimes coax a decent bead from a marginal setup, but it’s an uphill battle.
Quick Note: Polarity confusion isn’t unique to stick welding. Wire-feed processes flip their own rules, which is why Polarity for Flux Core Welding: DCEN vs DCEP trips up so many beginners too.
Once your rod matches your machine, the next variables are heat and technique. Getting comfortable with those takes deliberate reps, and a structured approach helps, as covered in Welding Practice: The Complete Guide to Building Real Welding Skills.
Setting your machine is where most beginners freeze. The dials look simple until you realize that a rod that runs perfectly at 100 amps on flat plate will stick, sputter, or blow a hole the moment you change position or size. Think of amperage, rod diameter, and position as three linked variables. Change one, and the others usually need attention too.
A thicker rod carries more current and lays down more metal. That means the amperage range printed on the package climbs as diameter increases. A 3/32 in rod is a light-duty electrode for thin material and out-of-position work, while a 1/8 in rod is the workhorse for general fabrication. The AWS A5.1 specification defines the electrode classifications, but the actual usable range comes from each manufacturer’s data sheet.
Here is how the numbers shake out for the two rods beginners reach for most.
| Electrode | Diameter | Current | Range (A) |
|---|---|---|---|
| E6013 (Lincoln Fleetweld 37) | 3/32 in | AC | 75–115 |
| E6013 (Lincoln Fleetweld 37) | 3/32 in | DC | 70–105 |
| E6013 (Lincoln Fleetweld 37) | 1/8 in | AC | 110–140 |
| E6013 (Lincoln Fleetweld 37) | 1/8 in | DC | 100–135 |
| E7018 | 3/32 in | DCEP | ~70–110 |
| E7018 | 1/8 in | DCEP | ~90–160 |
Notice that E7018 is a low-hydrogen rod with different characteristics, and it runs on DCEP. If polarity still confuses you, this explanation of DCEN, DCEP, and AC covers the idea cleanly, and the same logic applies to stick. E7018’s wide range on 1/8 in (roughly 90–160 A) means position and joint type decide where you land inside it, so trust the datasheet over guesswork.
Amperage is heat, and heat control is the whole game.
Gravity is the reason. In the flat position, molten metal pools nicely and you can push the amps. Move to vertical or overhead and the same puddle wants to sag and drip, so you turn the current down and travel faster. Washington Alloy lists E6013 1/8 in at about 80–130 A for flat work but only 60–110 A for vertical and overhead. That drop is the single most useful adjustment a beginner can make.
A practical rule: start in the lower third of the flat range, then add 5–10 amps until the arc sounds like frying bacon and the toes of the bead wet out cleanly.
Quick Note: The amperage ranges on a package or datasheet are a starting point, not gospel. Every machine reads its dial a little differently, and cable length changes actual output.
Learn to read the puddle, not the dial. A well-set arc gives a smooth, consistent crackle; if it pops and hisses, you are usually too hot, and if it stutters and sticks, you are too cold. Adjust in small 5-amp steps and give each change a few inches of bead before judging it.
Always begin with the manufacturer’s published range, then tune on scrap of the same thickness. Run a stringer, break it, and look at the penetration. If you want more structure for that practice, our welding practice guide lays out drills that build real control. One more sizing shortcut: pick a rod one size smaller than the base metal thickness for standard single-pass welds. On 1/8 in plate, that means a 3/32 in rod.
Almost every stuck rod, ugly bead, and cracked weld traces back to one of ten repeatable mistakes. Here is each one with the symptom you will actually see, the cause hiding behind it, and the fix that works. Stick welding rewards small corrections, so fix the symptom in front of you first, then work down the list.
Quick Note: If a bead looks wrong, read it before changing settings. Learning to judge good and bad welds transfers directly to stick.
| Symptom | Likely Mistake | First Fix |
|---|---|---|
| Rod sticks to plate | Too cold / wrong polarity | Raise amps, check leads |
| Heavy spatter | Arc too long | Shorten arc |
| Burn-through | Rod too big / amps too high | Smaller rod, less heat |
| Porosity | Damp rods | Dry or re-bake electrodes |
| Slag inclusions | Slag not cleaned | Chip between passes |
| Machine shuts down | Duty cycle exceeded | Let it cool |
Think of this table as a first-response checklist. Most bead problems are really heat, angle, or cleanliness problems in disguise, and each fix points you toward the one variable to change.
Fix these ten and most beginner frustration disappears. Reinforce the habits with deliberate welding practice, and the rod stops fighting you.
Most beginners treat welding rods like drill bits: toss them in a drawer and grab one when needed. That habit works fine for E6013 and E6011, but it will quietly ruin E7018. The difference comes down to two words you will see everywhere once you start reading datasheets: low-hydrogen.
Every stick electrode has a flux coating, and that coating’s chemistry decides how it behaves in storage. E6013 and E6011 use a rutile or cellulose-based flux. These coatings are moisture-tolerant, so a little humidity does not wreck them. They are forgiving enough that you can leave them out and still get a decent bead.
E7018 is different. Its flux is basic and specifically designed to be low-hydrogen. In its factory-fresh state, the coating holds very little moisture. Leave it exposed to humid air, however, and the flux absorbs water vapor. That water becomes a source of hydrogen that gets dissolved into the molten weld pool.
As the weld cools and solidifies, trapped hydrogen tries to escape but often cannot. It migrates into the heat-affected zone just below the weld, building up pressure. The result is underbead cracking (also called hydrogen-induced or delayed cracking), which can appear hours or even days after welding. A joint that looked perfect can fail overnight. As the AWS A5.1/A5.1M:2025 specification makes clear, low-hydrogen electrodes must be stored and handled correctly to perform as intended, because moisture absorption directly degrades weld quality.
Quick Note: A perfect-looking E7018 bead means nothing if the rod sat in a damp garage for a month. Hydrogen cracks hide until load is applied.
Manufacturers fight this with two tools: rod ovens (holding electrodes at a warm, dry temperature between 200°F and 300°F) and sealed, hermetic containers. For hobbyists, a sealed rod tube with a desiccant pack does the same job on a small scale. Your welding facility setup should include a designated dry-storage spot away from grinding dust and open windows.
Newer specifications let you choose electrodes with guaranteed low moisture. E7018 can be supplied to supplemental diffusible hydrogen limits identified by suffixes such as H4R. The number (H4, H8, H16) is the maximum diffusible hydrogen in milliliters per 100 grams of weld metal, so lower is better. The “R” means the electrode passed a moisture-resistance test, confirming it stayed dry even after controlled exposure. This is why the AWS A5.1 test requirements now include a moisture test of the low-hydrogen electrode as a classification requirement.
Build the dry-storage habit from day one. It is one of the small routines that separates scrap from solid work, and it pairs well with any structured welding practice plan.
That sweet burnt smell after a stick weld is not harmless. Welding fume is a cloud of metallic oxides created as the rod, its flux coating, and the base metal vaporize in the arc and then condense into particles small enough to reach deep into your lungs. Its composition shifts with the process and electrode, so the same rod that’s fairly benign on clean mild steel can release far worse on coated or alloyed stock.
The biggest risk in beginner stick welding comes down to what’s in the fume:
Fumes from stainless steel, cadmium, or lead-coated steel are considerably more toxic than those from iron or mild steel. Treat them with extra respect.
Quick Note: Metal fume fever shows up hours after welding as flu-like symptoms: breathing difficulty, cough, muscle pain, fever, and chills. It usually fades, but it’s a clear sign your ventilation is failing.
Fume output isn’t uniform. Stick welding uses a consumable flux coating that burns off in the arc, so shielded metal arc welding tends to generate more visible fume than gas-shielded processes. That flux is one reason electrode selection matters for your lungs, not just your weld quality.
OSHA set a PEL of 5 mg/m³ as an 8-hour time-weighted average for welding fumes from iron, mild steel, or aluminum. That sounds generous until you realize a small garage can reach it fast. NIOSH classifies welding fume as a potential occupational carcinogen linked to lung cancer and recommends controlling total fume to the lowest feasible concentration.
| Hazard | Exposure Limit | Source |
|---|---|---|
| Iron, mild steel, aluminum fume | 5 mg/m³ (8-hr TWA) | OSHA / NIOSH |
| Hexavalent chromium, Cr(VI) | 5 µg/m³ (8-hr TWA) | OSHA |
Your first line of defense is moving the fume away before you breathe it:
Respirators only work when they seal. A half-mask with P100 filters handles most mild-steel fume, but it must be fitted, and facial hair breaks the seal. For stainless, Cr(VI), or confined spaces, step up to a supplied-air system.
Don’t count on an open garage door as ventilation. Dilution alone rarely keeps up with the plume at the arc, which is why local exhaust is the standard approach. A properly planned shop makes this much easier, as our guide to setting up safe welding facilities explains.
Fume is only half the story. The arc throws intense ultraviolet light that burns skin like sunburn and can inflame the cornea — welder’s “arc eye,” which feels like sand in your eyes hours later. Never look at an arc without a helmet. Use a shade 10 to 13 lens for stick welding, and pick a shade that lets you see the puddle without squinting. Our guide to protective eyewear for welding covers shade selection in detail.
Cover exposed skin with leathers, button your collar, and keep bystanders behind a screen. Good habits from hour one beat a painful lesson later.
Here’s the good news: you don’t need a wall of electrodes to start learning. A focused, low-cost shopping list will carry you through your first several months of practice. The trick is knowing what to buy, how much, and when a brand name actually earns its price.
For a home hobbyist, the smart move is to skip the box and buy a 1 lb tube or two. Begin with 3/32 in and 1/8 in E6013, the two sizes that cover most beginner thickness work. Buy both so you can feel how rod diameter changes your travel speed and heat. Then add a small amount of E6011 for dirty, rusty, or painted metal, and a tube of E7018 once you want stronger, structural-grade welds. That’s it. Four tubes, one process, and plenty to practice on.
If you want a structured plan for spending that practice time wisely, our welding practice guide maps out exactly how to build real skill with each rod.
Quick Note: Electrodes are sold in sizes from 1/16 in up to 1/4 in. For beginners, 3/32 in, 1/8 in, and 5/32 in cover almost everything you’ll weld. The AWS A5.1 specification defines the standard sizes, lengths, marking, and packaging for carbon steel electrodes.
Bigger boxes are cheaper per pound, but that doesn’t make them a better buy for you. A 1 lb tube of E6013 runs a few dollars and lets you test a size before committing. A 10 lb box makes sense once you know the rod works for your machine and your projects. The catch is E7018: it absorbs moisture, and a big box you open and use slowly will degrade over months. Buy E7018 in smaller quantities unless you’re welding regularly.
Lincoln, Hobart, Harris, ESAB, and Washington Alloy all sell reliable, hobbyist-friendly rods. So do cheap imports. What are you paying for with a name brand?
For general practice on mild steel, budget rods often weld fine. As you move to structural or code work, the named brands earn their premium.
Prices swing by brand and process, but the pattern holds: general-purpose mild steel rods cost the least, low-hydrogen E7018 costs a bit more, and specialty stainless or aluminum rods jump significantly. Buying a single 1 lb tube of each lets you find what your machine likes for less than one 10 lb box.
A stick “welding rod” is a flux-coated electrode you clamp in your stinger. Filler wire is a spool of bare or flux-cored wire that feeds through a MIG or flux-core gun. They are not interchangeable, and the packages look similar. If you’re actually heading toward wire feeding, learn how to use a wire welder first, and understand what MIG wire is made of before you buy a spool.
One last sizing note: mild steel electrodes like E6013 and E7018 are your starting point. Stainless (E308L, E309L) and aluminum (E4043) rods exist for other base metals, but don’t stock them until a project calls for them.
You have the rod, the polarity, and the amperage. What you need now is a plan that turns awkward first strikes into beads you trust. Ten focused hours is enough to build real muscle memory, if you practice with intention instead of just burning rods.
Follow these steps in order. Don’t skip ahead; each drill feeds the next. Twenty minutes a day beats three hours once a week.
Quick Note: Keep a settings log every session. Record rod type, diameter, amperage, polarity, and position. That turns each practice session into usable data you can repeat instead of guesswork.
That log becomes your personal cheat sheet. When a bead runs well, you know exactly what produced it. When it fails, you change one variable at a time instead of guessing. Over a month, it tells you which combination actually works for your machine and your hands.
Your goal is not pretty beads yet. It is consistency. A good stringer has even width, steady ripples, and edges that tie into the plate without undercut or overlap. If beads wander, your travel speed is changing. If they sit tall and lumpy, your arc is too short or your amps are too low. Change one variable at a time and rerun the pass. Film a short clip of your beads; watching them back exposes drift you cannot feel in the moment.
As your skills grow, so should your rod selection. Matching electrode tensile strength and composition to the base metal prevents cracking and weld discontinuities. Start with E6013 on clean mild steel, add E6011 for dirty or rusty metal, and graduate to E7018 for structural work once your technique is steady. Verify specifications against the AWS A5.1 electrode standard.
If you remember one lesson, make it this: keep it simple. E6013 on clean mild steel teaches arc control without fighting a rod that demands perfect technique. Learn polarity and amperage on that forgiving electrode, then reach for E6011 and E7018 as your skills grow. And never skip fume control. Stick welding throws fumes and UV radiation, and OSHA’s welding hazards guidance puts ventilation and PPE first.
Every good welder once stuck a rod to the plate and swore. The difference is not talent. It is repetition with a plan. Put in your ten hours, keep your notes, and your next bead will hold. When you want to go further, our welding practice complete guide is the natural next step.
E6013 is widely considered the easiest rod to learn on because it strikes and restarts easily, runs on AC or DC, produces a soft arc with low spatter, and has slag that almost falls off. Start with 3/32 in and 1/8 in E6013 on clean mild steel, then add E6011 for dirty metal and E7018 for stronger structural welds as your skills improve.
Per the AWS A5.1 classification, the ‘E’ means electrode, the first two digits are the minimum weld tensile strength in thousands of PSI, the third digit indicates welding positions, and the last digit describes the flux coating and compatible current. So E6013 is a 60,000 psi all-position rutile rod, while E7018 is a 70,000 psi all-position low-hydrogen rod.
Most E7018 electrodes run on either AC or DCEP (electrode positive). They are not designed to run on DCEN. Always check the manufacturer’s datasheet, because some product-specific versions are optimized for one current type.
Sticking is usually caused by too little amperage for the rod diameter, too long an arc, or bad technique on restart. Turn the amps up within the recommended range for that rod size, shorten your arc, and use a scratch or tap start rather than holding the rod against the plate.
General-purpose rods like E6013 and E6011 tolerate normal storage well, but low-hydrogen rods such as E7018 absorb moisture that can cause hydrogen cracking. Keep E7018 in a sealed container with desiccant or a rod oven and re-dry it only according to the manufacturer’s instructions.
No. A welding rod is a coated stick electrode used in shielded metal arc welding (SMAW) that supplies both filler metal and its own flux shield. MIG uses a bare continuous wire fed through a gun with an external shielding gas, which is a completely different process and setup.
Yes. Welding fumes contain metallic oxides from the base metal, the rod, and its coating, and NIOSH classifies welding fumes as a potential occupational carcinogen. OSHA limits welding fumes from iron, mild steel, and aluminum to 5 mg/m3 as an 8-hour average, so work outdoors or use strong ventilation and a fume extractor, and never weld in a closed garage without airflow.
For thin sheet metal, use a small diameter with a soft arc, such as 3/32 in or 5/64 in E6013, and run the lowest amperage that still maintains a stable arc. Larger rods and high amperage cause burn-through on thin material.
A typical 1/8 in E6013 runs around 110-140 amps on AC and 100-135 amps on DC according to manufacturer data, though flat work often sits at the higher end and vertical or overhead work at the lower end. Treat the datasheet as a starting window and fine-tune on scrap.
