0445850032 - ESAB V-K Knurled Drive Roll 1.2mm / 1.4mm

Reliable Wire Feeding with ESAB V-K Rollers

The ESAB Feed Roller V-K 1.2 1.4 (0445850032) is a critical component for maintaining consistent welding performance in industrial environments. Designed specifically for ESAB wire feeding systems, this roller features a specialized "V-K" groove geometry. The "K" designation typically indicates a knurled surface, which is essential when feeding flux-cored or metal-cored welding wires. Unlike solid wires, cored wires require positive traction to prevent slippage, but they must not be crushed by excessive tension. The knurled teeth on this roller bite gently into the wire surface, providing the necessary push force to overcome friction in the liner and gun cable.

This particular roller is a dual-size unit, accommodating 1.2mm (0.045") and 1.4mm wire diameters. This versatility allows welders to switch between wire sizes simply by reversing the roller, reducing the need to carry multiple spare parts. Manufactured from high-grade hardened steel, the roller is built to withstand the abrasive nature of welding wire and the mechanical stress of continuous operation. Proper wire feeding is the backbone of a stable arc; worn or incorrect drive rolls can lead to burn-backs, bird-nesting, and erratic welds. By using genuine ESAB replacement parts, you ensure that your equipment operates at peak efficiency.

Installation is straightforward and tool-free on most ESAB feeders. Simply release the pressure arm, remove the retaining mechanism, and swap the roller. Ensure the desired wire size marking faces inward (or as per your machine's manual) to align the correct groove with the wire guide. Whether you are fabricating heavy structural steel or performing maintenance repairs, this feed roller ensures your wire is delivered smoothly to the weld pool.
