The Thermal Arc 376246-004 Drive Roll Kit is a critical replacement component for maintaining the wire feed system of your Thermal Arc MIG welder. Engineered for use with solid MIG wires, this roller features a V-groove profile that provides the necessary friction to push wire through the liner and contact tip without crushing or deforming it. This specific kit is compatible with popular multi-process machines such as the Fabricator 181i, 211i, and 252i.
The roller is designed with a reversible configuration. It accommodates .024-inch (0.6mm) wire on one side and .030-inch (0.8mm) wire on the other. This dual-functionality reduces the number of spare parts you need to keep on hand and allows for rapid changeovers in the shop. Proper drive roll tension and condition are paramount for stable arc characteristics; if your current rollers are worn or grooved incorrectly, you may experience arc stuttering or burn-back.
Installing this genuine OEM part restores your machine's feeding capability to factory specifications. The V-groove design is specifically intended for hard wires (like ER70S-6 mild steel or stainless steel). For flux-cored wires, a knurled roller would be required, but for standard solid wire MIG welding, this smooth V-groove is the industry standard for preventing wire shaving and liner clogging.
