268847 - Miller XR Aluminum Drive Roll Kit .030-.035 Polished U-Groove

Smooth Feeding for Aluminum MIG Welding

Struggling with birdnesting or erratic wire feeding while welding aluminum? The issue might be your drive rolls. The Miller 268847 Kit is the solution for welders using Miller XR Series push-pull systems. This kit is specifically tailored for .030 and .035 aluminum wire. Unlike the drive rolls used for steel, these feature a Polished U-Groove. This specific shape and finish are crucial because they cradle the soft aluminum wire rather than biting into it.

Using the wrong rolls on aluminum often leads to wire shavings—tiny flakes of aluminum that scrape off the wire and clog up your liner. Once your liner is clogged, your feed speed fluctuates, your arc sputters, and you end up with a frustrating mess. By installing the 268847 kit, you ensure that the wire glides through the feeder smoothly. The polished surface provides just enough traction to push the wire without deforming it, ensuring your wire comes out of the contact tip straight and true.

This kit is a direct replacement for Miller XR systems, making installation quick and easy. Whether you are building boat hulls, repairing trailers, or fabricating signage, reliable wire feeding is the foundation of a good aluminum weld. Don't let poor feeding ruin your bead; ensure your machine is equipped with the correct polished drive rolls for the job.
