376246-005 - Thermal Arc .052/.068 Drive Roll Kit (2-Roll System)

Precision Drive Roll Kit for .052 and .068 Welding Wire

The Thermal Arc 376246-005 Drive Roll Kit is an engineered component designed to facilitate the precise delivery of welding wire in MIG and Flux-Cored Arc Welding (FCAW) processes. This kit is specifically configured for 2-roll wire feed systems and features dual-groove geometry to accommodate wire diameters of .052 inches and .068 inches. Proper drive roll selection is critical for achieving a stable arc, as it directly influences the consistency of wire feed speed (WFS) and amperage.

Manufactured to tight tolerances, these drive rolls provide optimal traction on the welding wire. The groove profile is designed to maximize surface contact area while minimizing deformation of the wire cross-section. This is particularly important for tubular wires, such as flux-cored or metal-cored wires, where excessive pressure can distort the wire and lead to feeding issues within the gun liner or contact tip. By using the correct size roll for the wire diameter, operators can maintain lower drive roll tension settings, reducing wear on the feed motor and extending the life of the gun liner.

This kit is intended for use with compatible Thermal Arc wire feeders and integrated welding power sources. The 2-roll configuration typically involves a driven bottom roll and a pressure-adjustable top roll (or two driven rolls depending on the specific feeder model), working in tandem to push wire through the torch cable. The inclusion of grooves for both .052 and .068 sizes allows for rapid changeovers in production environments where different wire sizes are utilized for varying material thicknesses or welding procedures.

Regular inspection and replacement of drive rolls are recommended as part of a preventative maintenance schedule. Signs of wear, such as smoothed-out grooves or metal buildup, indicate the need for replacement. Installing the 376246-005 kit ensures that your equipment continues to meet the rigorous demands of industrial welding applications, providing the reliability required for code-quality welds.
