375980-030 - Tweco .035/.045 V-Groove Drive Roll Kit for Fabricator Series

Keep Your Wire Running Smoothly

There is nothing more frustrating than a wire feeder that slips, stutters, or birdnests right in the middle of a bead. Often, the culprit isn't the liner or the tip—it's a worn-out drive roll. The Tweco 375980-030 Drive Roll Kit is the direct replacement part you need to get your Thermal Arc or Tweco Fabricator welder running like new again. If you are running solid MIG wire, this V-Groove roll is exactly what the doctor ordered.

This roll is a two-in-one deal. It’s reversible, meaning you get a slot for .035" wire on one side and .045" wire on the other. This covers the vast majority of general fabrication jobs, from auto body repairs to heavy structural steel brackets. You don't need to keep track of two separate tiny wheels in your toolbox; just flip this one over when you decide to bump up your wire size. It’s made from tough hardened steel, so it bites into the wire just enough to push it through the liner without crushing it or creating metal shavings that clog your liner.

Why V-Groove? If you use knurled rollers on solid wire, you're going to chew up the copper coating and create drag in the liner. If you use U-groove, you might not get enough traction on steel wire. V-Groove is the sweet spot for solid mild steel and stainless wire. It cradles the round wire perfectly, giving you consistent traction.

Installation is a breeze. Pop the old one off, check the side of this roll for the size stamping, and slide it on with the size you want to use facing the correct direction (usually the size you are using is stamped on the side facing in, but check your manual to be sure). Tighten it down, set your tension, and you are ready to burn wire. Don't let a cheap worn-out part ruin your welds—grab a fresh drive roll and keep your arc steady.
