KP1505-035C - Lincoln Electric KP1505-035C 4-Roll Drive Kit for .030-.035 Cored Wire

Smooth Feeding for Flawless Flux-Cored Welds

Every welder knows that a stable arc starts with a smooth wire feed. The Lincoln Electric KP1505-035C Drive Roll Kit is your solution for frustrating feeding issues when running .030 to .035 inch cored wires. Flux-cored and metal-cored wires are softer and more compressible than solid MIG wire, making them susceptible to crushing if the wrong drive rolls are used. This kit is specifically engineered to grip these tubular wires firmly without deforming them, ensuring that the flux inside remains undisturbed and the wire stays round for optimal electrical contact at the tip.

This 4-roll kit is a game-changer for welders using Lincoln's professional-grade feeders like the Power Feed or Flex Feed systems. The 4-roll design provides superior traction compared to 2-roll systems, allowing you to use less tension on the drive rolls while still achieving positive feeding. This reduction in pressure is crucial for cored wires, as it prevents the "flattening" effect that causes friction in the liner and contact tip. The result is a consistent wire speed that lets you focus on your puddle manipulation and travel speed, rather than fighting the machine.

Installation is straightforward, as the kit comes with everything you need for a full setup: four matched drive rolls, guide tubes, and a feed plate. The inclusion of the correct guide tubes is vital; they support the wire as it enters and exits the rolls, preventing it from wandering or buckling—a common cause of the dreaded "birdnesting" at the feeder. Whether you are welding out of position on a structural beam or performing high-speed fabrication in a shop, reliable wire delivery is the foundation of a good day's work.

Designed for versatility, this kit supports a wide range of applications from automotive repair to heavy equipment maintenance. If you are switching your machine over to run small diameter flux-cored wire for a specific job, having the KP1505-035C on hand ensures you can make the transition quickly and get to welding. Don't let poor feeding ruin your beads; equip your Lincoln feeder with the drive rolls designed to handle the unique properties of cored wire.
