KP52079-052A - Lincoln Electric .052 Aluminum Drive Roll Kit (KP52079 Series)

Smooth Feeding, Better Welds

Anyone who has welded aluminum knows the struggle of wire feeding. It is soft, it bends if you look at it wrong, and it loves to birdnest right at the drive rolls. If you are running .052-inch aluminum wire, the Lincoln Electric KP52079-052A Drive Roll Kit is the upgrade your machine needs to keep you welding instead of troubleshooting. These rolls are designed specifically to handle the delicate nature of aluminum, ensuring that your wire makes it from the spool to the puddle without any drama.

Using the wrong drive rolls—like the V-grooves meant for steel—on aluminum is a recipe for disaster. They dig into the wire, creating tiny shavings that clog up your liner and contact tip. This leads to an unstable arc, sputtering, and eventually, the wire fusing to the tip. The rolls in this kit are designed to grip the wire gently but firmly. They provide the traction needed to push the wire through the gun cable without crushing it or shaving off metal. This means you get a smooth, consistent feed speed, which makes controlling your puddle and laying down a stack of dimes much easier.

This kit comes ready to work. It includes two drive rolls, which is standard for most feeder setups. But Lincoln didn't stop there; they also included the set screws and the hex key you need to install them. There is nothing worse than getting a new part and realizing you don't have the right tool to put it on. With this kit, you can swap out your old, worn-out rolls in minutes and get back to work. Whether you are fixing a pontoon boat or fabricating a custom aluminum tank, these rolls help ensure your equipment isn't the bottleneck.

Don't let feeding issues ruin your day or your welds. Worn drive rolls can slip, causing your wire speed to fluctuate and your arc to stutter. By replacing them with this genuine Lincoln Electric kit, you restore your machine's performance. The .052 size is precision-matched to your wire, eliminating the slop that causes alignment issues. Invest in the right parts for the job and experience the difference that smooth, reliable wire feeding makes on your aluminum projects.
