KP674-035S - Lincoln Electric Drive Roll Kit for .025-.035 Solid Wire - Wire-Matic & SP Series

Smooth Feeding for Your Trusted Lincoln Welder

There is nothing more frustrating than a welder that sputters and spits because the wire isn't feeding right. If you are running a Lincoln Wire-Matic 255 or one of the classic Idealarc SP-series machines, you know these workhorses are built to last, but their wear parts eventually need replacing. The Lincoln Electric KP674-035S Drive Roll Kit is exactly what you need to get your machine feeding like new again. Designed specifically for solid wire sizes .025, .030, and .035 inches, these rolls grab the wire firmly and push it through the liner smoothly, so you can focus on your puddle, not your feeder.

Over time, drive rolls can wear down, or the grooves can get clogged with debris, leading to slipping wire and inconsistent arc starts. If you've noticed your wire speed fluctuating or your arc hunting, it might be time to swap out your rolls. This kit is a direct replacement for the original parts on the Wire-Matic 255, SP-150, SP-250, and SP-250-I. Because it's a genuine Lincoln part, you don't have to worry about fitment issues—it slides right onto the drive shaft and locks in place, ready to work.

This kit is set up for solid wire, meaning the grooves are shaped to cradle the round wire without crushing it. This is crucial because if you flatten the wire with the wrong rolls, it won't fit through your contact tip properly, causing drag and burn-backs. Whether you are welding thin auto body sheet metal with .025 wire or fabricating brackets with .035, these rolls ensure the wire gets to the joint consistently. Don't let a cheap wear part slow down your project.

Installation is quick and easy, getting you back under the hood in minutes. Keep your welds clean and your frustration low by ensuring your wire feeder is equipped with fresh, correct drive rolls. The KP674-035S is the standard for reliability in these classic Lincoln machines, helping you lay down smooth beads day in and day out.
