10-6179 - Tweco / Thermal Arc 10-6179 Drive Roll .030/.035 V-Groove

Precision Wire Feeding for Professional Results

The Tweco / Thermal Arc 10-6179 Drive Roll is a critical component for maintaining arc stability and weld quality in MIG welding operations. Designed specifically for use with Thermal Arc Fabricator series power sources (including the 181i, 211i, and 252i), this drive roll features a dual-groove configuration that supports both .030-inch (0.8mm) and .035-inch (0.9mm) wire diameters. This versatility allows operators to switch between common wire sizes simply by reversing the roll, maximizing efficiency in dynamic shop environments.

Engineered with a Smooth V-Groove profile, this roll is optimized for solid welding wires such as mild steel (ER70S-6) and stainless steel. The V-shape provides four points of contact to grip the hard wire firmly without crushing it, ensuring consistent feed speeds and preventing wire shaving or bird-nesting. Proper drive roll selection is paramount for preventing feed issues; using this dedicated V-groove roll for solid wire eliminates the slippage often associated with incorrect roller types.

Manufactured to tight tolerances, the 10-6179 ensures concentric rotation and alignment with the wire guide, reducing wear on the liner and contact tip. Whether you are performing automotive bodywork, light fabrication, or maintenance repairs, this genuine replacement part restores the original feeding performance of your welding system.
