079609 - Miller 1/16" VK-Groove Drive Roll Kit for Flux-Cored Wire

Reliable Wire Feeding for Flux-Cored Applications

The Miller Drive Roll Kit (079609) is a specialized accessory designed to enhance the performance of your Miller MIG welder or wire feeder. Specifically engineered for 1/16-inch (1.6 mm) wire, this kit features VK-Groove drive rolls, also known as knurled rolls. Unlike standard smooth grooves used for solid wire, these rolls have a textured surface that bites into the wire, providing the necessary traction to push softer, tubular wires through the liner without slipping.

This kit is intended for use with Miller equipment featuring a 2-roll wire drive system. The 2-roll configuration is common in many compact and industrial wire feeders, providing a balance of simplicity and reliability. When welding with flux-cored or metal-cored wires, maintaining consistent wire speed is critical for arc stability. Slippage at the drive rolls can lead to burn-back, erratic arcs, and poor weld quality. By upgrading to the correct VK-Groove rolls, you ensure that your machine delivers wire smoothly and consistently, allowing you to focus on your puddle rather than troubleshooting your feeder.

In addition to the two drive rolls, the package includes an inlet wire guide. This component is crucial for aligning the wire as it enters the drive assembly, reducing drag and wear on the mechanism. Whether you are performing heavy fabrication or maintenance repairs, using genuine Miller parts like the 079609 kit ensures that your equipment operates at its peak potential. This kit is a direct replacement for worn-out rolls or a necessary conversion kit when switching from solid wire to flux-cored applications.

Investing in the correct drive rolls is a small step that makes a significant difference in your welding projects. The knurled design of these rolls handles the unique mechanical properties of tubular wire, preventing the crushing effect that can occur with incorrect tension settings on smooth rolls. Keep your operations running smoothly with this essential Miller accessory.
