ED511230 - Lincoln 7018AC 3/32" Stick Electrode

Smooth Welding on Any Machine

If you have ever tried to run a standard 7018 rod on an old AC "buzz box" welder, you know the frustration: the rod sticks, the arc stutters, and it keeps cutting out. The Lincoln Electric 7018AC 2.5mm electrode is the solution to that headache. Lincoln engineered this rod specifically for welders who need the strength and code-quality of a 7018 low-hydrogen weld but are working with an AC power source. It runs buttery smooth where other rods fail, giving you a stable arc that doesn't fight you.

At 2.5mm (roughly 3/32"), this rod is a versatile size for general repairs, fabrication, and farm work. It's small enough to handle slightly thinner materials without blowing through but carries enough filler metal to build up strong joints on thicker steel. The slag coverage is excellent and peels off easily, leaving you with a clean, professional-looking bead. Plus, because it's an all-position rod, you can tackle vertical-up or overhead welds without the puddle dripping out on you.

Don't let your machine limit your weld quality. Whether you are fixing a trailer frame, repairing a bucket on a tractor, or doing structural work in the shop, the Lincoln 7018AC gives you the confidence of a high-strength bond. It also works perfectly fine on DC+ if you switch machines, making it a versatile addition to your rod oven. Remember to keep these rods dry—moisture is the enemy of a good low-hydrogen weld!
