KP655-052C - Lincoln Electric KP655-052C Drive Roll & Guide Tube Kit for .045-.052 Cored Wire

Optimize Your Welding with the Lincoln KP655-052C Drive Roll Kit

Achieving the perfect weld starts with consistent wire feeding, and for welders using flux-cored or metal-cored wires, the Lincoln Electric KP655-052C Drive Roll Kit is the key to success. Designed to fit the LN-9, LN-9 GMA, and Synergic 7F/7FH wire feeders, this kit is tailored for wire sizes between 0.045" and 0.052". When welding with cored wires, the structural integrity of the wire is softer than solid wire, making it prone to crushing if the wrong drive rolls are used. This kit features a 4-roll system that grips the wire firmly yet gently, ensuring smooth delivery to the weld pool.

The 4-roll design is a significant upgrade for heavy-duty welding. It provides superior traction compared to 2-roll systems, allowing for consistent wire speeds even when the gun cable is bent or long. This consistency is crucial for maintaining a stable arc and achieving deep penetration, especially in out-of-position welding or when working on large fabrications. The knurled or specifically grooved surface of the rolls (typical for cored wire) bites into the wire just enough to push it through the liner without shaving off metal or deforming the flux core.

Installation of the KP655-052C is straightforward, allowing welders to switch setups quickly and get back to work. The kit includes not just the rolls but also the appropriate guide tubes. These tubes are essential for aligning the wire perfectly with the grooves of the rolls, preventing the wire from wandering or scraping against the feeder housing. Proper alignment reduces wear on the feeder motor and the gun liner, extending the life of your entire welding setup.

Whether you are working in a shipyard, a structural steel plant, or a heavy equipment repair shop, reliability is non-negotiable. The Lincoln KP655-052C ensures that your wire feeder performs as expected, shift after shift. Don't let poor feeding ruin your welds or cause unnecessary downtime. By using the correct drive roll kit for your specific wire size and type, you eliminate one of the most common variables in welding troubleshooting. Trust in Lincoln Electric's engineering to keep your arc smooth and your production moving.

This kit is specifically designated for cored steel wire. If you are switching from solid wire to flux-cored, swapping your drive rolls to this KP655-052C set is a mandatory step for optimal results. It supports the unique feeding requirements of cored wires, preventing the flattening that can occur with V-groove rolls designed for solid wire.
