375980-080 - Tweco .035 Flux-Cored Drive Roll Kit for 4-Roll Feeders

Tweco .035" Knurled Drive Roll Kit for 4-Roll Systems

Keep your industrial wire feeder running at peak performance with the Tweco 375980-080 Drive Roll Kit. Designed specifically for .035" (0.9mm) welding wire, this kit is the go-to solution for welders running flux-cored or dual-shield processes. If you are experiencing wire slippage, erratic feeding, or burn-back issues, worn or incorrect drive rolls are often the culprit. This kit provides a fresh set of rolls designed to restore the positive traction needed for high-quality welding.

Optimized for Tubular Wire

Flux-cored wires require special handling compared to solid MIG wires. Because they are tubular structures filled with flux powder, they lack the compressive strength of solid steel wire. Using smooth V-groove rolls often leads to a frustrating cycle: the wire slips, so you tighten the tensioner; the wire then crushes, causing it to stick in the tip. The knurled texture on these Tweco drive rolls solves this problem by providing "teeth" that grip the wire securely without requiring excessive down-pressure. This ensures the wire stays round, feeds smoothly through the liner, and makes good electrical contact at the tip.

Designed for 4-Roll Feeders

This kit is configured for 4-roll wire drive systems, which are the standard for industrial-grade welding performance. 4-roll systems effectively double the contact area with the wire compared to standard 2-roll feeders. This added traction is critical when pushing soft flux-cored wires, especially when using longer MIG guns (15ft or 25ft). By installing this kit, you ensure that your machine can deliver wire at constant speeds, even when the cable is bent or twisted. This results in a stable arc, reduced spatter, and less downtime clearing bird-nests.

Installation and Compatibility

Swapping out your drive rolls is a quick maintenance task that pays dividends in weld quality. This kit is compatible with select Thermal Arc and Tweco wire feeders and power sources (check your machine's manual for part number verification). The rolls are made from hardened steel to resist wear from the abrasive nature of flux-cored wires, ensuring a long service life even in high-volume production environments. Don't let poor feeding ruin your welds—upgrade to the correct knurled rolls for your application.
