0558102384 - ESAB .045 V-Knurled Drive Roll Set (2-Pack)

ESAB 0558102384 Feed Roll Set: .045" V-Knurled

The ESAB 0558102384 is a specialized set of feed rolls designed to optimize the performance of ESAB wire feeding systems when utilizing .045-inch (1.2mm) tubular wires. This set includes two precision-engineered rolls featuring a V-Knurled (VK) groove geometry. Unlike smooth V-grooves used for solid wires, the VK profile incorporates a textured surface within the groove. This texture bites gently into the surface of the wire, providing mechanical traction that allows the feeder to push the wire through the liner and gun with minimal drive roll tension.

These rolls are critical components for Flux-Cored Arc Welding (FCAW) and Metal-Cored Arc Welding (MCAW) applications. Tubular wires are inherently more fragile than solid wires; excessive roll tension can deform the wire's cross-section (ovality), leading to poor electrical contact in the contact tip and erratic arc performance. The knurled design mitigates this by ensuring positive feeding at lower pressure settings. Manufactured from hardened steel, these genuine ESAB parts are built to withstand the wear and tear of high-volume industrial fabrication environments.

Proper maintenance of the wire feed system is essential for weld quality. Using the correct drive roll geometry for the specific wire type and diameter prevents common feeding issues such as bird-nesting, burn-back, and inconsistent wire stick-out. This kit (0558102384) ensures that your ESAB equipment operates at peak efficiency when running .045" cored consumables.
