079596 - Miller .045 V-Groove Drive Roll Kit for Solid Wire

Precision Wire Feeding for Professional Results

The Miller 079596 Drive Roll Kit is an essential component for maintaining the performance of your Miller MIG welding system. Designed specifically for feeding .045-inch (1.2 mm) solid wires, this kit features V-Groove drive rolls that provide the optimal balance of grip and wire protection. Unlike knurled rolls which are designed for flux-cored wires and can deform solid wire, or U-groove rolls designed for soft aluminum, these V-Groove rolls are precision-machined to cradle hard solid steel and stainless steel wires. This geometry ensures consistent wire feed speed, which is critical for maintaining a stable arc and achieving high-quality welds.

This comprehensive kit includes two drive rolls and one inlet wire guide. The inlet guide is a critical, often overlooked component that aligns the wire as it enters the feeder mechanism, preventing wear on the housing and ensuring smooth entry into the drive rolls. Replacing the inlet guide simultaneously with the drive rolls is a best practice that restores your wire feeder to factory-level performance. The components are manufactured to Miller's exacting OEM standards, ensuring durability and a perfect fit within the drive assembly.

Broad Compatibility

One of the key advantages of the 079596 kit is its versatility across the Miller product line. It is compatible with a wide array of industrial wire feeders and integrated MIG machines. This includes the legendary Millermatic series (200, 210, 212, 250, 251, 252, DVI, Pulser, and Vintage) as well as the rugged Suitcase Series (Suitcase RC, S-32S) and 22, 32, 52 series feeders. It also fits Swingarc single 12/16 wire feeders and Millermatic DVI-2, 400, Dimension NT 450, and XMT WCC welding systems. This cross-compatibility makes it a staple inventory item for shops running multiple generations of Miller equipment.

Whether you are fabricating structural steel or performing precision stainless work, the reliability of your wire feed system is paramount. Slipping wire leads to burnback, irregular bead profiles, and frustration. By installing the Miller 079596 V-Groove Drive Roll Kit, you ensure that your machine delivers the wire smoothly and consistently, allowing the operator to focus on the puddle rather than the equipment.
