OVERVIEW

Optimize Your MIG Welder Performance

Upgrade or maintain your Lincoln Electric MIG welder with the KP674-045S Drive Roll Kit, designed to deliver flawless wire feeding performance. This kit is the factory-specified replacement for .035" to .045" solid wire setups on several popular Lincoln machines, including the Wire-Matic 255 and the SP-255/SP-250 series. In MIG welding, the drive roll system is the heart of the wire feeder; if the rolls are worn or mismatched to the wire type, you will experience erratic feeding, burn-backs, and frustration.

The KP674-045S utilizes a smooth V-groove design, which is the industry standard for feeding solid hard wires like carbon steel and stainless steel. Unlike knurled rolls used for flux-cored wire which bite into the metal, these smooth V-groove rolls provide traction through surface contact area. This ensures the copper coating on your welding wire remains intact and the wire stays round, preventing clogging in the contact tip. This attention to detail results in a smoother arc, less spatter, and a more enjoyable welding experience.

Key Compatibility:

  • Wire-Matic 255
  • Idealarc SP-255
  • Idealarc SP-250
  • Idealarc SP-250-I

Investing in OEM parts like the KP674-045S ensures that your equipment operates within its original specifications. The kit includes the necessary components to refresh the drive mechanism of your feeder. Heavy usage can cause grooves to widen or lose their grip, necessitating replacement. By keeping a fresh set of drive rolls installed, you ensure that the wire feed speed set on the machine matches the actual wire output, providing the control you need for critical welds. Don't let poor feeding compromise your work; equip your Lincoln welder with the correct drive rolls for the job.

FAQ

This drive roll kit is designed for solid wire sizes ranging from .035 inches to .045 inches (0.9mm to 1.2mm).

No, these are V-groove rolls designed for solid wire. Flux-cored wire typically requires knurled drive rolls to prevent crushing the hollow wire.

It is compatible with the Wire-Matic 255, Idealarc SP-255, SP-250, and SP-250-I welding systems.

Yes, the kit typically includes the necessary rolls to outfit the drive assembly for the specified machines.

V-groove rolls provide traction without deforming the solid wire or flaking off the copper coating, which ensures smooth feeding through the liner and contact tip.

Drive rolls should be replaced when the grooves show signs of wear or when you can no longer get consistent feeding without over-tightening the tensioner.

Yes, the KP674-045S is a genuine Lincoln Electric replacement part.

No, this kit is specifically for the older Wire-Matic and SP series. Power MIG machines typically use different drive roll kits (like the KP1696 series).
