KP3285-1 - Lincoln Electric .035/.045 V-Knurled Drive Roll Kit for Magnum 100SG

Smooth Feeding for Your Flux-Cored Projects

If you are experiencing sputtering, irregular arcs, or wire slippage while welding with your small Lincoln Power MIG, the issue might not be your technique—it could be your drive roll. The Lincoln Electric KP3285-1 Drive Roll Kit is the essential upgrade or replacement part you need to get back to laying down smooth beads. Designed specifically for the Magnum 100SG feeder found on many compact Lincoln machines, this roll is a must-have for anyone running flux-cored wire.

Flux-cored wire is softer than solid wire because it is a hollow tube filled with flux. If you use a standard smooth roller and tighten it down enough to grip the wire, you risk crushing it into an oval shape. This deformed wire drags inside the gun liner and makes poor contact at the tip. The KP3285-1 solves this with its V-Knurled design. The tiny teeth in the groove grab the wire securely without needing excessive pressure. This means the wire stays round, feeds smoothly, and gives you a consistent, stable arc that makes welding easier and more enjoyable.

Versatility is key in any shop, and this drive roll delivers. It is reversible, featuring a groove for .035" wire on one side and .045" wire on the other. Switching sizes is as simple as flipping the roll over. Whether you are repairing heavy farm equipment with thick flux-core or doing general fabrication with solid wire, this roll ensures your machine feeds reliably. The kit comes complete with the installation key, so you have everything you need to swap it out in seconds and get back to work.
