W4017010 - Lincoln Electric .035/.045 V-Groove Drive Roll Kit (Set of 2)

Precision Wire Feeding for Industrial Applications

The Lincoln Electric .035" & .045" V-Groove Drive Roll Set is an essential component for maintaining the operational integrity of high-performance MIG wire feeding systems. Designed specifically for industrial environments where arc stability and feed consistency are paramount, these drive rolls are engineered to handle solid welding wires, including mild steel and stainless steel. The kit includes two rolls, typically utilized in 2-roll or 4-roll drive systems found in professional Lincoln Electric wire feeders and power sources.

The V-groove profile is critical for solid wire applications. Unlike knurled rolls which bite into the wire (suitable for flux-cored), or U-groove rolls designed for soft aluminum, the V-groove provides necessary friction for traction while maintaining the roundness of the wire cross-section. This prevents shaving or deformation of the copper coating, reducing the accumulation of debris in the liner and contact tip. The rolls are manufactured from hardened steel to resist wear from the constant friction of the moving wire, ensuring a long service life even under high duty-cycle conditions.

This set features a dual-configuration capability, accommodating both 0.035-inch (0.9 mm) and 0.045-inch (1.2 mm) wire diameters. This versatility simplifies inventory management for maintenance departments and allows operators to quickly adapt their machine setup to different welding procedure specifications (WPS). Proper installation and tensioning of these rolls are vital; excessive tension can deform the wire, while insufficient tension leads to slippage and burn-back. These rolls are machined to tight tolerances to ensure concentricity and smooth rotation.
