W4017212 - Lincoln Electric V-Knurled Drive Roll Kit 5/64-3/32 Inch

Precision Wire Feeding for Industrial Applications

The Lincoln Electric W4017212 Drive Roll Kit is an essential component for maintaining optimal performance in heavy-duty wire feeding systems. Engineered specifically for large diameter wires, this kit accommodates 5/64-inch and 3/32-inch sizes, making it suitable for high-deposition welding processes often found in structural steel, shipbuilding, and heavy equipment manufacturing.

The defining feature of these drive rolls is the V-Knurled groove geometry. Unlike smooth V-grooves used for solid wires or U-grooves for aluminum, the knurled texture provides mechanical teeth that bite gently into the surface of flux-cored and metal-cored wires. This design is critical for these softer, tubular wires as it allows the feeder to push the wire through long gun cables without requiring excessive drive roll tension that could crush the wire and deform its cross-section. By maintaining the wire's roundness, these rolls ensure consistent electrical contact at the contact tip and reduce arc instability.

This kit includes a set of two matched rolls, ensuring balanced torque transfer in dual-gear driven systems. Manufactured from high-grade hardened steel, they are built to withstand the abrasive nature of knurled feeding and the rigors of continuous industrial use. Proper installation of these rolls ensures that wire feed speed remains constant, directly impacting weld quality and deposition rates.
