KP674-045C - Lincoln Electric .045 Knurled Drive Roll Kit for SP-255/WM-255

Precision Wire Feeding for Cored Applications

The Lincoln Electric KP674-045C Drive Roll Kit is an essential accessory for professional welders utilizing 0.045-inch cored wires. Specifically engineered for the Wire-Matic 255 and Idealarc SP-255 welding systems, this kit ensures your equipment operates at peak efficiency. When working with flux-cored or metal-cored wires, standard smooth V-groove rolls often fail to provide adequate traction, leading to slippage and inconsistent arc performance. Conversely, excessive tension can crush the tubular wire, causing feeding issues and liner clogging.

This kit solves those challenges with a specialized knurled groove design. The teeth of the knurled surface bite gently into the wire's sheath, providing positive drive force without the need for excessive pressure. This results in smooth, uninterrupted wire delivery, which is critical for maintaining a stable arc and achieving high-quality weld deposits. Whether you are performing general fabrication or heavy-duty structural welding, reliable wire feeding is the foundation of a good weld.

Manufactured to Lincoln Electric's exacting standards, these drive rolls are built for durability and long service life. The kit includes the necessary components for a complete changeover, allowing you to switch your machine setup quickly and get back to work. By using genuine Lincoln Electric parts, you ensure perfect fitment and compatibility, protecting your investment in your welding power source.
