20312254 - Tweco .045 Inch (1.2mm) Replacement Drive Roll

Stop Fighting Your Wire Feeder

There are few things more frustrating in the shop than a wire feeder that stutters, slips, or birds-nests right in the middle of a bead. If you are constantly adjusting your tension knob or fighting burn-backs, the problem might not be your liner or your tip—it might be your drive rolls. The Tweco Drive Roll for .045" (1.2mm) Wire is the direct replacement you need to get your machine running smoothly again. Worn grooves lose their grip, forcing you to crank down the tension, which only flattens the wire and causes it to shave off inside the liner, creating a whole new set of problems.

This drive roll is built tough to handle the daily grind of fabrication work. It features a precision groove that cradles .045" wire perfectly, giving you positive traction without the need for excessive pressure. Whether you are running solid steel wire for structural work or manufacturing parts, consistent wire speed is the key to a consistent weld. When your wire feeds smoothly, your arc stays stable, your puddle is easier to control, and your spatter levels go down.

Don't let a small, inexpensive part cost you hours of downtime and frustration. Swapping out your drive rolls is one of the easiest maintenance tasks you can do to improve your welding experience immediately. We recommend keeping a spare set in your toolbox or on the machine cart so you aren't left stranded when a roll finally wears out. This genuine Tweco part ensures a perfect fit for your compatible feeder, getting you back under the hood and burning wire with confidence.

Remember to check your drive rolls every time you change a spool. If the grooves look worn or the teeth (if knurled) are dull, it's time to swap them out. This simple check can save you from troubleshooting phantom electrical issues or liner clogs later on. Get the grip you need with this high-quality replacement roll.
