KP502-7/64H - Lincoln LN-8/LN-9 Drive Roll Kit for 7/64 Hardfacing Wire

Reliable Feeding for Tough Jobs

When you are laying down hardfacing, the last thing you need is a wire feeder that slips or jams. The Lincoln Electric KP502-7/64H Drive Roll Kit is built to handle the demands of 7/64-inch hardfacing wire, ensuring that your LN-8 or LN-9 feeder delivers a smooth, consistent supply of wire to the puddle. Hardfacing wire can be notoriously difficult to feed due to its stiffness and surface texture, but with the right drive rolls, you can eliminate feeding issues and focus on laying down a quality bead.

Precision Engineering

This kit isn't just a set of wheels; it's a complete feeding solution. It includes matched drive rolls and guide tubes that are specifically calibrated for 7/64" diameter wire. The guide tubes play a crucial role in supporting the wire as it travels through the feeder, preventing it from buckling or scraping against the housing. The drive rolls are designed to grip the wire firmly without crushing it, providing the positive traction needed to push heavy wire through the gun cable without hesitation. This precision translates to a stable arc and better weld appearance.

Minimize Downtime

Time spent fixing birdnests or adjusting tension is time not spent welding. By using the correct KP502-7/64H kit for your application, you significantly reduce the risk of feeding failures. Whether you are rebuilding crusher rollers, bucket teeth, or other heavy equipment, reliability is key. These genuine Lincoln Electric parts are manufactured to tight tolerances, ensuring they last longer and perform better than generic alternatives. Keep your production line moving and your welds consistent with equipment designed for the task at hand.

Upgrade Your Feeder

If you are converting your LN-8 or LN-9 feeder for a hardfacing project, this kit is the mandatory upgrade you need. Don't rely on standard V-groove rolls meant for solid wire; they simply won't provide the grip required for large-diameter hardfacing consumables. Invest in the KP502-7/64H to ensure your equipment is set up for success from the very first arc strike.
