375832 - Thermal Arc 375832 Top Knurled Drive Roll .030-.035 for Fabricator 252i

Reliable Feeding for Your Fabricator 252i

When you are running flux-cored wire on your Thermal Arc Fabricator 252i, the difference between a smooth day of welding and a frustrating one often comes down to your drive rolls. The Thermal Arc 375832 Top Drive Roll is the specific solution for welders using .030 to .035 inch flux-cored wire. If you have ever experienced wire slipping, burn-back, or the dreaded birdnesting at the feeder, you know that traction is key. Unlike solid wire which uses smooth V-groove rolls, flux-cored wire is softer and hollow. Using the wrong roll can crush the wire, changing its shape from round to oval, which causes drag in the liner and contact tip.

This flat knurled drive roll features small teeth that bite gently into the surface of the wire. This allows you to back off the tensioner on your wire feeder, reducing the crushing force while still maintaining a positive, non-slip grip. The result is a consistent wire speed that matches your voltage setting, producing a stable, crisp arc that makes vertical and overhead welding much easier to control. This roll is designed as the top gear in the feed mechanism and is built to withstand the rigors of daily shop use.

Installation is straightforward and requires no special tools, allowing you to swap between solid wire setups and flux-cored setups in minutes. Whether you are fabricating structural steel, repairing heavy equipment, or working on general maintenance projects, ensuring your Fabricator 252i is equipped with the correct 375832 knurled roll is the first step to high-quality welds. Don't compromise your weld bead appearance or integrity with slipping wire; rely on genuine Thermal Arc components to keep your machine running at peak performance.
