KP666-045C - Lincoln SP-175 Plus Knurled Drive Roll Kit .035-.045

Reliable Wire Feeding for Flux-Cored Applications

The Lincoln Electric KP666-045C Knurled Drive Roll Kit is an essential component for welders utilizing the SP-175 Plus system for flux-cored arc welding. When working with cored wires, standard smooth V-groove rollers often fail to provide adequate traction unless tightened to the point of deforming the wire. This kit solves that problem with a precision-engineered knurled surface that bites gently into the wire's surface, ensuring consistent feed rates without crushing the hollow tubular structure of the consumable.

Designed specifically for wire diameters ranging from .035 inches to .045 inches (0.9 mm to 1.2 mm), this drive roll kit is the key to achieving professional results in structural and maintenance welding. Poor wire feeding is one of the most common causes of frustration in MIG and flux-cored welding, leading to burn-backs, bird-nesting, and unstable arcs. By installing the correct drive roll for your specific wire type, you eliminate these variables, allowing you to focus entirely on your puddle and bead appearance.

Installation is straightforward and requires no specialized tools, making it easy to swap out your drive rolls when changing between solid and cored wires. The durability of the hardened steel construction ensures that the knurling maintains its grip over long periods of heavy use. Whether you are a hobbyist repairing farm equipment or a professional fabricator, the KP666-045C ensures your Lincoln Electric equipment operates at peak performance.

Investing in genuine Lincoln Electric parts guarantees compatibility and performance. This kit is manufactured to the tight tolerances required by the SP-175 Plus wire drive mechanism, ensuring perfect alignment with the wire guide and liner. Don't let slippage compromise your weld quality; upgrade to the appropriate knurled drive roll for all your flux-cored projects.
