0367556006 - ESAB VK-G Knurled Drive Roll for Flux-Cored Wire .035-.062

Precision Wire Feeding for Cored Applications

The ESAB Feed Roll VK-G (SKU: 0367556006) is a specialized drive component designed to optimize the performance of ESAB wire feeding systems, specifically the Warrior and Origo series. Engineered with a V-Knurled (VK) groove geometry, this roll is essential for the reliable feeding of tubular wires, including gas-shielded flux-cored (FCAW-G), self-shielded flux-cored (FCAW-S), and metal-cored (MCAW) consumables.

Unlike smooth V-groove rolls used for solid wires, the VK profile features teeth that bite gently into the wire's surface. This mechanical interlock allows for lower drive roll tension settings, which is critical for cored wires that are susceptible to crushing or deformation under high pressure. Deformation of cored wire can lead to poor electrical contact in the contact tip and erratic arc characteristics. The "G" designation typically indicates a geared mechanism, ensuring positive engagement with the drive system for slip-free rotation.

This specific roll covers a versatile range of wire diameters, indicated as .035"-.045" and .052"-.062", making it a flexible solution for shops running multiple wire sizes. Manufactured from hardened steel, it resists wear from the abrasive nature of knurled wire interaction, maintaining consistent feed speeds over long production cycles.
