KP655-052S - Lincoln LN-7/LN-9 Solid Wire Drive Roll Kit .045-.052

Reliable Feeding for Your Lincoln Wire Feeder

Keep your production line moving and your welds consistent with the Lincoln Electric KP655-052S Drive Roll Kit. When your wire feeder starts slipping or feeding erratically, it’s often a sign that your drive rolls are worn or mismatched to your wire size. This kit is the direct replacement solution for Lincoln LN-7, LN-9 GMA, LN-742, and Synergic 7 wire feeders running .045" to .052" solid wire. Don't let poor feeding ruin a good weld; ensure your equipment is set up correctly with genuine OEM parts.

The KP655-052S is a 4-roll kit, meaning it provides four points of contact on the wire. This design allows for excellent feeding force with less crushing pressure compared to 2-roll systems. For solid wire, this balance is key to preventing wire deformation which can cause drag inside the gun liner. The kit includes everything you need for a complete changeover: the drive rolls themselves and the matching guide tubes. The guide tubes are often overlooked, but they are vital for guiding the wire precisely into the roll grooves and out into the gun cable. Worn guide tubes can cause the wire to wander, leading to shavings and jams.

Designed for industrial environments, these components are built from hardened steel to withstand the rigors of daily use. Whether you are running mild steel or stainless solid wire in the specified diameter range, this kit ensures smooth, uninterrupted delivery to the contact tip. Proper maintenance of your wire feeder is the easiest way to improve weld quality and reduce frustration. With the KP655-052S, you can trust that your Lincoln feeder will perform as intended, delivering the wire smoothly for a stable, spatter-free arc.

Compatibility Check: This kit is specifically for the LN-7 and LN-9 series feeders. Please verify your feeder model and wire size before ordering to ensure a perfect fit.
