170924-010 - Thermal Arc .045 V-Knurled Bottom Drive Roll for Fabricator 252i

Optimize Your Fabricator 252i for Flux-Cored Welding

Upgrade or maintain your Thermal Arc Fabricator 252i with the 170924-010 V-Knurled Bottom Drive Roll. This specialized component is essential for welders utilizing .045" flux-cored wire. Whether you are working on structural steel, heavy fabrication, or outdoor repairs where gas-shielded MIG isn't feasible, flux-cored welding requires a robust feeding system. This drive roll provides the mechanical advantage needed to push tubular wire through the gun liner smoothly and consistently.

The "V-Knurled" design distinguishes this roll from standard equipment. The serrated teeth inside the groove dig slightly into the surface of the flux-cored wire. This positive engagement means the drive system relies on mechanical locking rather than friction alone. Consequently, you can reduce the pressure on the idle roll, preventing the hollow wire from being flattened or deformed. Flattened wire causes accelerated wear on contact tips and can lead to arc instability or burn-backs. By using the 170924-010, you ensure the wire remains round and feeds at the precise speed set on your machine.

Installation and Maintenance:

Replacing drive rolls on the Fabricator 252i is a straightforward process requiring no special tools. This part is the bottom roll, which typically seats directly onto the drive shaft keyway. It is crucial to pair this with the appropriate top pressure assembly (sold separately or part of your existing setup if compatible). Regular inspection of drive rolls is recommended; over time, the knurling can wear down or become clogged with metal shavings and lubricant, reducing effectiveness. A fresh drive roll is a low-cost investment that prevents frustrating wire feed problems.

Why Choose Genuine Thermal Arc Parts?

Thermal Arc parts are manufactured to tight tolerances. The 170924-010 is made from hardened steel to resist wear, even under the high-volume demands of industrial welding. It fits perfectly into the Fabricator 252i's feed mechanism, ensuring proper alignment with the wire guide and gun liner. Don't compromise your weld quality with worn-out or incorrect feed rolls.

Whether you are running gas-shielded flux-core (Dual Shield) or self-shielded wires, this .045" knurled roll is the correct tool for the job. Ensure your setup is complete and ready for heavy-duty welding tasks.
