The Lincoln Electric KP674-035C Drive Roll Kit is a critical component for professional welders utilizing the Wire-Matic 255 or Idealarc SP-255 welding systems. Designed specifically for 0.035-inch to 0.045-inch (0.9mm - 1.2mm) cored wires, this kit addresses the unique challenges associated with feeding tubular welding consumables. Unlike solid wires, flux-cored and metal-cored wires have a hollow, composite structure that makes them susceptible to crushing if improper drive rolls are used. Deformed wire can lead to poor electrical contact in the contact tip, erratic arc characteristics, and feeding interruptions.
This OEM Lincoln Electric kit features drive rolls engineered to provide positive traction without compromising the structural integrity of the wire. The surface texture and groove geometry are calibrated to grip the softer cored wire firmly, preventing slippage even under the tension required for longer gun cables. By maintaining the roundness of the wire, the KP674-035C ensures consistent current transfer and smooth wire delivery to the weld pool, which is essential for achieving high-quality welds in structural and fabrication applications.
Regular inspection and replacement of drive rolls are vital for maintaining the reliability of your wire feeder. Worn drive rolls can cause wire slippage, leading to burn-back and downtime. This kit is a direct replacement for the SP-255 and WM-255 models, ensuring a perfect fit and alignment within the wire drive assembly. Installing genuine Lincoln Electric parts guarantees that your equipment operates within factory specifications, prolonging the life of the liner and gun consumables by reducing shaving and friction.
