171435-005 - Tweco .035/.045 V-Groove Drive Roll Kit for Fabricator Series

Reliable Wire Feeding for Tweco Fabricators

The Tweco 171435-005 Drive Roll Kit is an essential replacement component designed to maintain the peak performance of your MIG welding operations. Specifically engineered for the Tweco and Thermal Arc Fabricator series—including the popular 141i, 181i, 211i, and 252i multi-process welders—this drive roll ensures that your welding wire is fed smoothly and consistently through the liner to the contact tip. Inconsistent wire feeding is one of the most common causes of poor weld quality, leading to issues like burn-back, sputtering arcs, and irregular bead profiles. By utilizing genuine OEM drive rolls, you eliminate these variables and secure a stable arc for professional results.

This kit features a versatile dual-groove design. One side of the roll is machined for 0.035-inch (0.9 mm) wire, while the other accommodates 0.045-inch (1.2 mm) wire. This reversible functionality is incredibly convenient for shops that frequently switch between different wire gauges for various material thicknesses. The V-groove geometry is specifically optimized for solid steel wires (such as ER70S-6), providing the necessary grip to push the wire without deforming it or shaving off metal shavings that could clog your liner. Proper tensioning combined with the correct groove shape extends the life of your consumables and reduces downtime associated with wire feeding jams.

Installation is straightforward and tool-free on most compatible units. Simply remove the retention knob or screw, flip the roll to the desired size indicator facing inward (or as per your machine's manual), and re-secure. The durable steel construction of the 171435-005 ensures it withstands the friction and mechanical stress of daily welding, making it a long-lasting investment for your equipment maintenance. whether you are a hobbyist using a Fabricator 181i in a garage or a professional fabricating heavy structures with a 252i, this drive roll kit is the standard for reliability.
