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

Optimize Your MIG System with Tweco Drive Rolls

For professional welders, the wire feeding system is the heartbeat of any MIG setup. The Tweco 171435-005 Drive Roll Kit provides the precision and grip necessary to deliver solid welding wire accurately to the weld pool. Designed with a V-Groove profile, this roller is intended for use with hard wires, such as mild steel and stainless steel. The V-shape cradles the wire, allowing the drive motor to transfer torque effectively without crushing the wire, which is a common issue when using incorrect roller types (like knurled rollers on solid wire) that can lead to flaking and liner blockages.

This specific drive roll is a reversible component, offering distinct advantages for versatility on the job site. It supports .035" (0.9mm) and .045" (1.2mm) diameters, covering a vast range of fabrication applications from automotive bodywork to structural steel repairs. Changing the size is as simple as removing the roll and flipping it over; the size markings are typically stamped clearly on the side of the roll for easy identification. This reduces the need to carry multiple spare parts and simplifies inventory for workshops running multiple Fabricator series machines.

Compatibility is key with drive systems. The 171435-005 is the direct replacement part for the feed mechanisms found in the Thermal Arc / Tweco Fabricator 141i, 181i, 211i, and 252i. Using non-OEM or incorrect drive rolls can result in "micro-slippage," where the wire speed fluctuates imperceptibly to the eye but enough to destabilize the arc voltage and current. This leads to excessive spatter and poor fusion. By installing this fresh drive roll kit, you restore the mechanical integrity of your wire feeder, ensuring that the wire feed speed (WFS) you set on the digital display is exactly what is being delivered to the torch.
