132957 - Miller .045 VK-Groove Knurled Drive Roll for SuitCase Feeders

Reliable Feeding for Flux-Cored Welding

Every welder knows that a smooth, stable arc starts with consistent wire feeding. If you are running flux-cored or metal-cored wire, using the wrong drive rolls can lead to a host of problems, from wire slippage to crushing the wire out of round. The Miller .045 VK-Groove Drive Roll (132957) is the solution for these challenges. Designed specifically for .045 inch tubular wires, this roll features a knurled "VK" groove that bites into the wire just enough to push it through long gun liners without requiring you to crank down the tension arm. This means you get positive feeding without flattening the wire, which helps prevent contact tip burnback and erratic arc characteristics.

This drive roll is a must-have for welders using Miller's heavy-duty feeders. Whether you are out in the field with a SuitCase X-Treme 12VS welding structural steel or in the shop with a Miller 22A feeder, this roll fits perfectly and performs reliably. The knurled teeth on the groove provide the extra grip needed for cored wires, which often have lubricants or coatings that make them slippery. By using the correct roll, you reduce the chance of "bird-nesting" at the feeder, a frustrating issue that stops production and wastes wire.

Compatibility and Performance

The 132957 is built to Miller's high standards for durability. Flux-cored wire can be abrasive, but these hardened rolls are designed to withstand the wear and tear of high-volume welding. They are compatible with a broad lineup of Miller equipment, making them a versatile addition to your parts inventory. If you are switching your machine over from solid MIG wire to flux-core, swapping out your smooth V-groove rolls for these VK-groove rolls is the most important step in the setup process.

Don't let poor feeding ruin your welds or your day. Investing in the correct drive rolls like the Miller 132957 ensures that your equipment works as hard as you do. Remember to check your feeder's manual to see if you need a two-roll or four-roll setup, as these are sold individually. With the right drive rolls installed, you can focus on the puddle, not the feeder.
