375980-073 - Tweco 4-Roll Drive Kit 3/64 Inch

Smooth Feeding for Better Welds

Every welder knows that a smooth wire feed is the backbone of a good day in the shop. If your wire is slipping, stuttering, or bird-nesting at the feeder, you aren't welding—you're troubleshooting. The Tweco 375980-073 Drive Roll Kit is built to solve those headaches. Designed specifically for 3/64" (1.2mm) wire running on 4-roll feeders, this kit gives you the traction you need to keep the arc lit and the bead laying down flat.

Why does a 4-roll kit matter? Unlike 2-roll systems that have to clamp down hard to get a grip (often squashing the wire), a 4-roll system spreads the grip out. This kit takes full advantage of that, feeding your 3/64" wire smoothly without deforming it. This is huge if you are running aluminum or sensitive flux-cored wires where a crushed wire means a jammed tip five minutes later. These rolls are machined with precision grooves that grab the wire just right, ensuring that when you pull the trigger, the wire moves instantly and stops exactly when you let go.

Swapping out your drive rolls is one of the easiest ways to tune up your machine. If you've been fighting an erratic arc or hearing the motor whine as it tries to push wire, check your rolls. If they are worn out or the wrong size, this Tweco kit is the direct replacement you need. It’s durable, reliable, and made to fit your Tweco or compatible feeder perfectly. Don't let a cheap or worn-out part ruin your welds.

Get back to stacking dimes and stop fighting your feeder. With the Tweco 375980-073, you get consistent wire speed, which means consistent voltage and amperage at the puddle. It’s the professional choice for welders who demand reliability from their gear.
