7977732 - Thermal Arc .030-.035 V-Knurled Drive Roll Kit for Fabricator & Rebel

Optimize Flux-Cored Welding with Thermal Arc 7977732 Drive Rolls

The Thermal Arc 7977732 Drive Roll Kit is an essential component for welders utilizing the Fabricator 181i, Fabricator 211i, or ESAB Rebel series machines for flux-cored applications. Designed specifically to handle tubular wires, this kit features a V-Knurled groove geometry. Unlike smooth V-groove rollers used for solid MIG wire, V-Knurled rollers possess small teeth that grip the softer, flux-filled wire. This mechanical grip allows the wire feeder to push the consumable through the liner and gun without requiring excessive tensioner pressure, which can deform or crush flux-cored wires.

Covering the popular .030" (0.8mm) and .035" (0.9mm) diameter range, this kit ensures your multi-process welder operates at peak efficiency during structural or maintenance welding. Poor feeding is the leading cause of downtime in wire welding; symptoms include erratic arcs, burn-back, and bird-nesting at the feeder. By installing the correct 7977732 drive roll kit, operators ensure a smooth, consistent feed rate, which is critical for maintaining a stable arc and achieving high-quality weld deposits.

This genuine Thermal Arc part is manufactured to precise tolerances, ensuring perfect alignment with the wire guide and inlet. Whether you are working on heavy equipment repair or general fabrication, using the correct drive roll profile is paramount. The kit includes the necessary rolls to set up your machine for flux-cored welding immediately. Trust in genuine replacement parts to maintain the warranty and performance standards of your Thermal Arc and ESAB equipment.
