375980-040 - Tweco .035 Knurled Drive Roll Kit for Flux-Cored Wire

Achieve Smooth Flux-Cored Welding with Tweco Knurled Rolls

Frustrated by wire slipping, sputtering arcs, or bird-nesting at the feeder? If you are running flux-cored wire through your Tweco or Thermal Arc welder, the issue might be your drive rolls. The Tweco 375980-040 Drive Roll Kit is the upgrade you need to stabilize your wire feeding. Designed specifically for .035" flux-cored and dual-shield wires, these rolls feature a textured, knurled groove that grips the wire securely without the need for excessive tension.

Standard smooth V-groove rolls rely on friction and high pressure to move wire, which works fine for solid steel but is a disaster for hollow flux-cored wires. High pressure crushes the wire, changing its shape from round to oval, which increases drag in the gun liner and contact tip. This knurled kit solves that problem by using teeth to grab the wire, allowing you to back off the tensioner. The result is smooth, uninterrupted feeding, a consistent arc, and better-looking welds. Whether you are welding outdoors with self-shielded wire or in the shop with dual-shield, these rolls are the key to reliability.

This kit is a direct replacement for the stock rolls on many Fabricator series machines. Swapping them out takes only minutes but can save you hours of frustration and downtime. Don't let poor feeding ruin your project; ensure your machine is equipped with the correct hardware for the job. With the Tweco 375980-040 kit, you get durable, hardened steel rolls that are built to last and designed to keep you welding.
