375980-043 - Tweco .030/.035 V-Groove Drive Roll Kit for 4-Roll Feeders

Smooth Feeding for Flawless Welds

Nothing ruins a good weld bead faster than inconsistent wire feeding. If your wire is slipping, stuttering, or birdnesting at the drive rolls, it’s time to upgrade your feed system with the Tweco 375980-043 Drive Roll Kit. Designed for welders who demand reliability, this kit is built for 4-roll wire feeders, which are the gold standard for smooth, uninterrupted wire delivery. By utilizing four rolls instead of two, the system grips the wire firmly without crushing it, ensuring that your wire travels smoothly from the spool to the contact tip every time you pull the trigger.

This kit is specifically machined with V-grooves, making it the perfect choice for running solid MIG wires like ER70S-6 or stainless steel. The V-groove acts like a track, keeping the wire centered and moving forward with precision. Whether you are welding thin sheet metal with .030" wire or tackling structural frames with .035" wire, this kit has you covered. The rolls are reversible or clearly marked, allowing you to swap between sizes quickly so you can get back to welding rather than fumbling with tools.

Installing new drive rolls is one of the easiest and most effective maintenance tasks you can perform on your MIG machine. Worn grooves can cause slippage, leading to burn-back and unstable arcs. By replacing your old rolls with this genuine Tweco kit, you restore the mechanical integrity of your feeder. Compatible with Thermal Arc Fabricator units and other Tweco-style 4-roll feeders, this kit is an essential spare part for any serious fabrication shop or garage.
