Hobart 418 E7018-1 Low Hydrogen Stick Electrode 5.0mm

Smooth Running for Heavy Metal

When you are burning rod all day on heavy structural steel, you need a consumable that fights the job, not you. The Hobart 418 E7018-1 is built for welders who demand a smooth, buttery arc and slag that practically peels itself off. This 5.0mm (approx. 3/16") rod is a heavy hitter, designed to lay down serious metal on thick plates without compromising control. If you are welding on bridges, heavy machinery, or pressure vessels, this is the rod that helps you pass X-ray testing while keeping your travel speed up.

The "-1" in the 7018-1 designation means this rod is tougher than your standard 7018. It is tested to hold up in freezing temperatures, which is why it's a go-to for critical code work. But for the guy under the hood, what matters is how it runs. The Hobart 418 is known for its excellent arc stability—it doesn't stutter or wander, even if your fit-up isn't perfect. It produces a flat to slightly convex bead with distinct ripple patterns that make your work look professional. Spatter is kept to a minimum, so you spend less time with a chipping hammer and grinder and more time welding.

This 50lb can is the standard shop pack, keeping your rods dry until you are ready to load them into the oven. The 5.0mm size is perfect for filling large bevels and running heavy fillets in the flat position. While it is rated for all positions, gravity makes this large diameter a challenge for vertical-up, so it's best reserved for your heavy flat and horizontal joints. Compatible with both AC and DC+ machines, the Hobart 418 gives you the flexibility to weld with whatever power source is available on the site.

Why Welders Choose Hobart 418

It comes down to consistency. You don't want a rod that fingernails halfway through a pass or drops slag inclusions because the flux is inconsistent. Hobart 418 burns evenly down to the stub, giving you maximum usage out of every rod. It restarts easily for a low-hydrogen electrode, reducing porosity at the start of your welds. For heavy-duty repairs and fabrication where quality counts, this is a rod you can trust.
