There is nothing more frustrating than a wire feeder that slips, stutters, or birds-nests right in the middle of a critical weld. If you are running .035" flux-cored wire through your Thermal Arc Fabricator, the Tweco 171435-003 Drive Roll Kit is the upgrade you need to ensure smooth, consistent delivery. Standard smooth V-groove rollers rely on friction and pressure to move the wire, which works fine for solid steel. However, flux-cored wire is a hollow tube filled with powder; if you crank down the tension to get a grip with smooth rollers, you crush the wire into an oval shape. This causes drag in the liner and contact tip, leading to erratic arcs and burn-back.
This kit features a knurled groove—think of it like the tread on a tire or the teeth on a gear. These tiny teeth bite gently into the surface of the flux-cored wire, providing positive traction with very little tension pressure. This means your wire stays round, flows smoothly through the gun, and comes out at a constant speed. The result? A stable arc, better puddle control, and significantly less spatter. Whether you are welding structural steel outdoors or doing maintenance repairs in the shop, the reliability of your feed system starts here.
Designed specifically for the Thermal Arc Fabricator 181i, 211i, and 252i, this drive roll drops right in without modification. It’s a genuine part, meaning it’s built from hardened steel to withstand the wear and tear of daily fabrication work. Don't let a worn-out or incorrect drive roll ruin your welds. Swap in the 171435-003 and experience the difference that the right traction makes for your flux-cored projects.
