375980-050 - Tweco .035 V-Groove Drive Roll Kit for 4-Roll Feeders

Reliable Wire Feeding for Professional Results

In the world of MIG welding, the consistency of your wire feed is just as critical as your voltage settings or gas flow. The Tweco 375980-050 Drive Roll Kit is engineered to provide that essential reliability. Designed specifically for welders using .035-inch (0.9mm) solid wire, this kit features precision-machined V-groove rolls that grip the wire firmly without crushing it. This balance is crucial; too little grip causes slippage and burn-back, while too much pressure can deform the wire, leading to accelerated liner wear and contact tip issues.

Why Choose V-Groove?

Drive rolls come in various geometries, each suited for a specific type of wire. This kit utilizes a V-Groove design, which is the industry standard for solid steel and stainless steel wires. The "V" shape provides two points of contact that center the wire and drive it forward with positive traction. Unlike knurled rolls that dig into the wire, V-groove rolls maintain the smooth surface finish of your consumable, ensuring it passes through the gun liner and contact tip with minimal friction.

Optimized for 4-Roll Systems

This particular kit is designated for 4-roll wire feeder systems. Four-roll systems are superior to two-roll systems because they distribute the driving force over a larger surface area. This allows for consistent feeding with less pressure on the wire, virtually eliminating wire deformation. Whether you are fabricating structural steel or performing automotive repairs, upgrading or replacing your drive rolls with this genuine Tweco kit ensures your machine operates at peak performance. Worn drive rolls are a common, often overlooked cause of erratic arcs; refreshing them is a simple maintenance step that yields immediate improvements in weld quality.
