375980-004 - Tweco .045 Knurled Drive Roll Kit for Fabricator Series

Genuine Tweco .045" Knurled Drive Roll for Fabricator Series

Maximize the efficiency of your welding operations with the Tweco 375980-004 Drive Roll Kit, engineered specifically for feeding .045" (1.2mm) flux-cored and dual-shield welding wires. This component is a critical upgrade or replacement part for owners of Thermal Arc / Tweco Fabricator 181i, 211i, and 252i welding machines. When switching from solid MIG wire to flux-cored wire, changing your drive rolls to a knurled profile is mandatory to ensure smooth, uninterrupted wire delivery to the weld puddle.

The "FK/DS" designation indicates its suitability for Flux-Cored and Dual Shield applications. The roll features a textured, serrated groove that provides mechanical grip on the wire. This design allows the feed motor to push the wire through the liner and gun cable with minimal tension, which is crucial for softer tubular wires that can easily flatten or kink under the pressure of standard V-groove rolls. By maintaining the structural integrity of the wire, this drive roll helps prevent feed issues that lead to downtime and rework.

Manufactured to precise tolerances, this drive roll kit installs easily into the 2-roll drive systems found on compatible Fabricator units. Regular inspection and replacement of drive rolls are recommended to maintain consistent wire speeds and arc characteristics. Worn drive rolls can cause slippage, resulting in an erratic arc and poor penetration. Invest in genuine Tweco consumables to ensure your equipment continues to deliver the professional results you expect. This kit typically includes the drive roll necessary to convert your machine for heavy-duty flux-cored welding tasks.
