046780 - Miller .030 V-Groove 4-Roll Drive Kit for 50 Series Feeders

Smooth Feeding for Superior Welds

Nothing ruins a good weld bead faster than inconsistent wire feeding. If you are experiencing stuttering, slipping, or the dreaded bird-nesting at the feeder, it might be time to replace your drive rolls. The Miller 046780 Drive Roll Kit is the factory-original replacement for your heavy-duty Miller equipment, designed to get you back to welding with a smooth, steady arc. This kit is specifically built for running .030-inch solid wire, making it a staple for automotive, light fabrication, and stainless steel projects.

This isn't just a set of wheels; it is a complete 4-roll upgrade. If your machine uses a 4-roll system—like the robust 24A feeder or the Millermatic 350—you know the advantage it offers in traction. However, that advantage is lost if the V-grooves are worn out. These fresh V-Groove rolls grip solid wire firmly without crushing it, ensuring the wire stays round and feeds effortlessly through your liner and contact tip. Because this is a 4-roll kit, you get four drive rolls to completely refresh your feeder's grip.

Everything You Need in One Box

Switching wire sizes or refreshing your machine shouldn't be a scavenger hunt for parts. This kit includes not just the four drive rolls, but also the matching inlet guide and intermediate guide. The guides are often overlooked, but they are critical for keeping the wire aligned perfectly as it enters and travels through the drive assembly. Using the correct size guides prevents the wire from wandering or buckling under resistance.

Don't let worn consumables compromise your productivity. By installing genuine Miller drive rolls, you protect your wire feeder motor from unnecessary strain and ensure that your focus stays on the puddle, not on the feeder. Whether you are fabricating precision stainless parts or running mild steel production, the 046780 kit delivers the reliability professional welders demand.
