089984 - Miller .068-.072 V-Knurled Drive Roll & Guide Tube Kit

Keep Your Flux-Core Running Smoothly

If you are running heavy flux-cored wire, you know that slippage is the enemy of productivity. The Miller 089984 Drive Roll Kit is built to handle the heavy lifting of .068 and .072 inch wires without skipping a beat. When you are welding out of position or pushing wire through a long gun cable, you need drive rolls that bite. These V-Knurled rolls provide the teeth needed to grab the wire and push it consistently, ensuring your arc stays hot and your puddle stays controllable.

Using the wrong drive rolls—like smooth V-grooves—on flux-cored wire often forces you to crank down the tension knob just to get the wire to feed. This crushes the wire, causing it to drag in the liner and wear out contact tips prematurely. The Miller 089984 kit solves this with knurled rollers that grip with light tension, preserving the shape of your wire. This means fewer birdnests, less downtime clearing jams, and more time dropping beads.

This kit isn't just the rolls; it comes with the essential inlet guide tube. A worn or incorrect guide tube is a silent killer of feed performance, often causing the wire to wander before it even hits the rolls. By replacing both the rolls and the guide at the same time, you restore your feeder to factory-fresh performance for these specific wire sizes. Whether you are running a trusty Millermatic 250 or a shop-standard S-22 feeder, this genuine Miller kit is the upgrade you need for heavy-duty cored wire work.
