046781 - Miller .035 V-Groove Drive Roll Kit for 4-Roll Feeders

Smooth Wire Delivery for Superior Welds

Stop fighting with erratic wire feeding and upgrade your machine with the Miller 046781 Drive Roll Kit. If you are running .035-inch solid wire through a Miller 4-roll feeder, this is the exact kit you need to ensure smooth, uninterrupted welding. The drive rolls feature a precision-machined V-Groove, which is the industry standard for feeding solid mild steel and stainless steel wires. The V-shape wedges the wire firmly into the groove, providing excellent traction to push the wire through the liner and contact tip without slipping or crushing it.

Designed for the professional welder, this kit fits a variety of popular Miller wire feeders, including the 50 Series, 54 Series, and 24 Series models. The advantage of a 4-roll system cannot be overstated; it provides double the traction surface area compared to standard 2-roll systems. This means you can set your tension lower, preserving the shape of your wire and reducing strain on your feed motor. The result is a consistent wire speed that helps you lay down uniform beads with less spatter and fewer burn-backs.

Installation is straightforward and the kit includes everything required for a full changeover. You receive four matched drive rolls along with the essential inlet and intermediate wire guides. Worn guides are a common, often overlooked cause of feeding issues; they can develop grooves that snag the wire or allow it to wander. By installing the fresh guides included in this kit, you ensure the wire is perfectly aligned from the moment it enters the feeder until it leaves the drive assembly. Keep your Miller welder running at peak performance with genuine Miller parts.
