189285 - Miller .035-.045 V-Groove Drive Roll for Millermatic 350/350P

Keep Your Millermatic Running Smoothly

Don't let feeding issues slow down your fabrication projects. The Miller 189285 V-Groove Drive Roll is the factory-original replacement part you need to keep your Millermatic or industrial wire feeder operating at peak performance. Designed specifically for .035" to .045" solid wire, this drive roll ensures that your wire is fed consistently to the weld puddle, giving you the control you need for high-quality beads.

Why Choose Genuine Miller Drive Rolls?

When it comes to wire feeding, traction is everything. If your drive rolls are worn out, you might experience wire slippage, irregular arc starts, or frustrating "bird-nesting" at the feeder. The Miller 189285 features a precision-cut V-groove that grips solid wire firmly without crushing it. This is crucial for solid wire applications where maintaining the round shape of the wire ensures good electrical contact at the tip. By using genuine Miller parts, you guarantee perfect alignment with your machine's wire guide system, protecting your investment and ensuring your warranty remains intact.

Fits Your Favorite Machines

This drive roll is one of the most versatile in the Miller lineup, fitting a huge range of popular machines found in shops across the country. Whether you are running the advanced Millermatic 350P for pulsed MIG work, the workhorse S22A feeder, or the classic Millermatic 300, this is the correct roll for mid-range solid wire sizes. It is also compatible with the ST 44 and XMS series feeders.

Installation and Setup

Swapping out drive rolls is a quick process that can save you hours of troubleshooting later. Simply release the tension arm, remove the retaining knob or screw, and slide the new 189285 roll onto the shaft. Ensure you match the wire diameter stamped on the roll to the wire you are using. For 4-roll wire feeders, remember that you will typically need to replace both the top and bottom rolls (or all four rolls depending on the drive system design) to ensure even feeding pressure.
