151037 - Miller .047 U-Groove Drive Roll Kit for 60/70 Series Feeders

Precision Aluminum Wire Feeding for Industrial Applications

The Miller 151037 Drive Roll Kit is an essential accessory for professional fabricators utilizing Miller 60 Series or 70 Series wire feeders for aluminum welding applications. Feeding soft aluminum wire presents unique challenges compared to steel; the wire is pliable and prone to deformation, shaving, or "bird-nesting" if subjected to excessive pressure or friction. This kit is engineered specifically to address these issues, providing a reliable solution for running .047-inch (3/64-inch) wire with precision and consistency.

Optimized U-Groove Design

Unlike V-groove rolls designed for hard steel wires, the drive rolls in this kit feature a smooth U-Groove geometry. This shape cradles the round aluminum wire, providing sufficient traction for feeding without biting into the metal or distorting its cross-section. By maintaining the integrity of the wire shape, the kit ensures better electrical contact at the contact tip and reduces the accumulation of aluminum shavings within the liner, leading to cleaner welds and less downtime for maintenance.

Complete 4-Roll System

This kit is designed for 4-roll wire drive systems, which are superior for aluminum applications as they distribute the feeding force over a larger surface area. This allows for lower tension settings on the drive rolls while maintaining positive feeding. The package is comprehensive, including not just the four drive rolls, but also the critical guide components: an inlet wire guide, an intermediate wire guide, and an anti-wear guide. These guides are crucial for bridging the gaps between rolls, fully supporting the soft wire to prevent it from buckling under resistance.

Compatibility and Installation

Manufactured to Miller's exacting standards, the 151037 kit fits seamlessly into Miller 60 and 70 Series industrial feeders. Installation is straightforward, allowing operators to switch between wire types and sizes efficiently. Whether you are manufacturing trailers, boats, or signage, this drive roll kit ensures your equipment operates at peak performance, delivering the smooth arc characteristics required for high-quality aluminum welding.
