Lincoln Electric .035 Knurled Drive Roll Kit for Flux-Cored Wire

Stop Wire Slippage with Knurled Drive Rolls

Every welder knows the frustration of a sputtering arc caused by poor wire feeding. If you are running flux-cored or metal-cored wire, using the wrong drive rolls is often the culprit. The Lincoln Electric KP52079-035C Drive Roll Kit is the solution for welders running .035" (0.9 mm) cored wires. Unlike smooth rolls that rely on squeezing the wire to grab it, these knurled rolls have textured teeth that bite gently into the wire's surface. This means you can back off the tensioner, saving your wire from being crushed into an oval shape.

Why does this matter? When flux-cored wire is crushed by smooth rolls, it doesn't just feed poorly; it creates drag inside the liner and wears out contact tips faster because the wire is no longer perfectly round. By switching to the KP52079-035C knurled kit, you ensure positive feeding even if you are welding in difficult positions or have a loop in your gun cable. The teeth provide the grip needed to push the wire through without the excessive pressure that causes birdnesting at the drive assembly.

This kit is a genuine Lincoln Electric part, meaning it is built to last and fits your machine exactly as intended. It comes with the necessary guides to ensure the wire travels straight from the spool, through the rolls, and into the gun without snagging. Whether you are fabricating structural steel, repairing heavy equipment, or working on a farm repair, reliable wire feeding is the foundation of a good weld. Don't let slipping wire ruin your bead or your day.

Ideally suited for FCAW (Flux-Cored Arc Welding) and MCAW (Metal-Cored Arc Welding) processes, this kit is an essential upgrade for any welder switching from solid wire to cored wire. Keep your arc smooth, your puddle controllable, and your downtime to a minimum with the right drive rolls for the job.
