If you have ever tried running a standard 7018 rod on an old AC "buzz box" welder, you know the struggle: the rod sticks, the arc stutters, and you spend more time grinding than welding. The Hobart 18AC 1/8" stick electrode is the solution to those headaches. Designed specifically to run smoothly on AC power, this rod turns your utility welder into a fabrication powerhouse. It takes the frustration out of low-hydrogen welding by providing a steady, forgiving arc that doesn't cut out every time you blink.
The "18AC" isn't just a name; it's a promise of performance. These rods are famous for their easy starting and restarting capabilities. This makes them perfect for tack welding projects where you need to make quick, strong holds without fighting the rod. Whether you are fixing farm equipment, building a trailer, or working on a custom project in the garage, these electrodes lay down a smooth bead with minimal spatter. The slag cools quickly and often lifts right off, leaving you with a professional-looking weld that requires very little cleanup.
Don't let the "AC" label fool you—these rods are versatile. They run great on DCEN and DCEP too, giving you flexibility no matter what machine you plug into. They are built for all-position welding, so you can tackle vertical and overhead repairs without the puddle dripping out on you. With this 50lb can, you are stocked up for big projects, ensuring you have consistent, high-quality filler metal ready to go whenever the sparks need to fly. Upgrade your welding game and stop fighting your machine with Hobart 18AC.
