Atlantic CHE40 E6013 Welding Rod 3.2mm x 350mm - 5 kg Box

If you've been welding for a while, you already know the E6013 — it's the go-to rod for a reason. The Atlantic CHE40 is a solid, reliable mild steel electrode that lays down smooth, clean welds every time. Great for everyday structural work, sheet metal, and anywhere you want a nice-looking finish.

It runs on both AC and DC, strikes easy, and works in all positions. The slag comes off clean, and the bead has that smooth, shiny look that makes your work look professional.

Frequently Asked Questions — E6013 Welding Rods

1. What does E6013 mean, and how do I read the electrode classification?

The AWS classification breaks down like this: E = Electrode (stick/SMAW), 60 = minimum tensile strength of 60,000 psi (60 ksi), 1 = all-position (flat, horizontal, vertical, overhead), 3 = AC or DC current, medium penetration, rutile-based flux coating. The "3" suffix is what makes the E6013 so beginner-friendly — the rutile flux produces a soft arc, easy slag removal, and a smooth, visually clean bead.

2. What is the E6013 best used for?

The E6013 excels at general-purpose mild steel welding where appearance and ease of use matter. It's ideal for sheet metal fabrication, light structural work, maintenance and repair welding, farm equipment, automotive bodywork, and hobbyist projects. It's not the best choice for heavy structural or high-strength applications — for those, E7018 is typically specified. But for clean, everyday welds on mild steel, the E6013 is hard to beat.

3. What polarity should I use — AC or DC? And if DC, which polarity?

The E6013 runs on both AC and DC. If using DC, DCEP (DC Electrode Positive / Reverse Polarity) is the most common setting and gives good penetration and arc stability. DCEN (DC Electrode Negative) can also be used and produces a softer arc with less penetration — useful on very thin material. AC works well when you're running a basic transformer-style welder. The flexibility to run on AC makes the E6013 a great match for entry-level and farm welders.

4. What amperage should I set for 3.2mm (1/8") E6013 rods?

For the 3.2mm diameter in this box, the recommended range is 80–130A for flat position and 80–110A for vertical and overhead. Start in the middle of the range (around 100–110A) and adjust based on your arc behavior — if the rod sticks frequently, increase amperage; if you're getting excessive spatter or burn-through, reduce it. Material thickness, joint type, and welder brand all affect the ideal setting, so always dial in on scrap first.

5. What's the difference between E6013 and E6011 or E7018?

E6013 vs. E6011: The E6011 uses a cellulosic flux and produces deeper penetration — it's better for dirty, rusty, or painted metal and runs well on AC. The E6013 is smoother and easier to use but needs cleaner base metal. E6013 vs. E7018: The E7018 is a low-hydrogen electrode with higher tensile strength (70 ksi vs. 60 ksi) and is required for structural and code-critical welds. It must be kept dry in a rod oven. The E6013 is more forgiving to store and use, making it the everyday workhorse for non-code general fabrication.

6. Can E6013 rods weld rusty or dirty metal?

The E6013 performs best on clean, properly prepared base metal. While it has some tolerance for light surface scale, it is not designed for heavily rusted, painted, or galvanized surfaces. Welding over contaminated metal with E6013 can result in porosity, inclusions, and weak welds. For dirty or rusty conditions, E6011 is a better choice. Always grind or wire-brush the weld area clean before striking an arc with E6013 for best results.

7. How do I prevent the rod from sticking to the base metal?

Rod sticking is almost always caused by amperage set too low or arc length too short. To fix it: increase your amperage in 5–10A increments until the arc starts and maintains cleanly. Maintain an arc length roughly equal to the rod diameter (about 3mm for a 3.2mm rod). If the rod sticks, release the electrode holder immediately — don't yank — and let the rod cool before breaking it free. Running a quick bead on scrap to warm up the rod and dial in settings before moving to your workpiece also helps.

8. How should I store E6013 welding rods?

E6013 rods are relatively moisture-tolerant compared to low-hydrogen electrodes like E7018, but proper storage still matters. Keep them in a dry, sealed container or the original box away from humidity and temperature swings. If rods have been exposed to moisture and are producing excessive spatter or porosity, they can be reconditioned by baking at 200–250°F (93–121°C) for 1–2 hours. Unlike E7018, E6013 does not require a dedicated rod oven for normal storage — a dry shop environment is sufficient.

9. What material thickness can I weld with 3.2mm E6013 rods?

The 3.2mm (1/8") diameter is well-suited for material in the 3/16" to 1/2" (approximately 5mm to 12mm) range in a single pass, with multi-pass capability on thicker sections. For thinner sheet metal (under 3/16"), consider stepping down to a 2.0mm or 2.5mm rod to reduce heat input and minimize burn-through risk. For heavier plate over 1/2", a 4.0mm or 5.0mm rod will be more productive. The 3.2mm is the most versatile all-around size for general shop and field work.

10. Is this rod available for same-day pickup, and how many rods are in a 5 kg box?

⚠️ Safety

Always weld in a ventilated area, wear proper eye and body protection, and keep your head out of the fumes. Fumes, arc rays, and electric shock are serious hazards — follow your employer's safety guidelines.
