375980-062 - Tweco .045 Cogged Drive Roll Kit for 4-Roll Feeders

Smooth Feeding for Professional Welds

Every welder knows that a stable arc starts with a steady wire feed. If your wire is slipping, stuttering, or bird-nesting at the feeder, you aren't welding—you're troubleshooting. The Tweco 375980-062 Drive Roll Kit is the solution for welders running .045" wire on 4-roll feeder systems. This isn't just a standard set of wheels; these are cogged (geared) drive rolls designed to lock together and push that wire through your gun with authority.

Why does the "cogged" design matter? In a 4-roll system, you want every roll working together. The gears on these rolls ensure that they turn at the exact same speed, grabbing the wire from top and bottom without relying solely on crushing pressure. This means you can back off the tension knob a bit, saving your wire from deformation. Deformed wire leads to shavings in your liner and erratic contact at the tip. By using these precision-geared rolls, you keep the wire round and the feed smooth, resulting in a consistent burn-off rate and a bead that looks like a stack of dimes.

This kit is specifically sized for .045-inch (1.2mm) wire. Trying to run .045 wire through .035 rolls will shave the wire, and running it through 1/16" rolls will cause slipping. Using the exact size match provided by this kit ensures optimal traction. Whether you are fabricating structural steel, working on heavy equipment, or running long beads in a production environment, trusting your feed mechanism is half the battle. These rolls are built tough from hardened steel, so they won't groove out or wear down prematurely, even after running spool after spool.

Don't let a cheap or worn-out drive roll ruin your day under the hood. Swapping out your old rolls for a fresh Tweco 375980-062 kit takes just a few minutes, but it can save you hours of frustration. Keep your arc smooth, your puddle controllable, and your downtime to a minimum. If you are running a Tweco or Thermal Arc 4-roll feeder, this is the upgrade your machine needs to keep up with your work.
