CF-2.20.09.604 - 3/64" Aluminum U-Groove Drive Roll Kit

Precision Wire Feeding Solutions for Aluminum GMAW

The ComParc Drive Roll Kit (SKU: CF-2.20.09.604) is a critical component engineered to address the specific challenges of feeding aluminum welding wire. In industrial Gas Metal Arc Welding (GMAW) applications, the integrity of the wire feed system is paramount to achieving high-quality welds and maintaining production efficiency. Aluminum alloys, such as the commonly used 4043 and 5356 series, possess low column strength and high ductility compared to ferrous wires. Consequently, standard V-groove or knurled drive rolls are unsuitable, as they tend to compress the wire into an oval shape or abrade the surface. This deformation increases friction within the gun liner and contact tip, leading to erratic wire feed speeds (WFS) and arc instability.

Engineering and Performance

This kit features a precision-machined U-groove profile that is specifically sized for 3/64-inch (1.2 mm) wire. The U-groove design maximizes the contact area between the roller and the wire, allowing for effective traction at lower tension settings. This "cradling" effect prevents the crushing of the wire and eliminates the generation of aluminum shavings—a primary cause of liner clogging and equipment downtime. Manufactured from high-grade hardened steel, these rolls are designed to withstand the rigors of continuous industrial use while maintaining their dimensional accuracy. By ensuring the wire retains its round cross-section throughout the feed path, the ComParc drive roll kit facilitates laminar flow through the cable, which is essential for the high-speed feeding often required in aluminum fabrication.

Maintenance and Compatibility

For maintenance, repair, and operations (MRO) professionals, selecting the correct drive roll geometry is a fundamental aspect of preventive maintenance for welding equipment. The installation of the CF-2.20.09.604 kit is a direct intervention that reduces the frequency of contact tip burn-backs and birdnesting events at the feeder inlet. This component is compatible with specific wire feeder models designed for ComParc replacement parts, offering an OEM-equivalent solution that meets rigorous performance standards. It is an essential inventory item for facilities engaged in the fabrication of aluminum trailers, marine vessels, automotive components, and architectural structures.
