265256 - Miller .047 Aluminum U-Groove Drive Roll Kit (4-Roll Set)

Precision Feeding for Aluminum MIG Welding

The Miller 265256 Drive Roll Kit is a specialized accessory engineered to enhance the performance of Miller industrial wire feeders when welding with aluminum. Aluminum wire is inherently softer than steel and prone to deformation under pressure. This kit features a U-groove geometry that cradles the .047-inch (3/64") wire, providing the necessary traction for feeding without crushing the wire's cross-section. Maintaining the roundness of the wire is essential for good electrical contact at the tip and a stable arc.

A standout feature of this kit is the polished finish on the drive rolls. Unlike knurled or standard machined rolls, the polished surface significantly reduces friction and abrasion against the soft aluminum. This prevents the generation of aluminum shavings, which can accumulate in the gun liner and cause clogging or "birdnesting" at the feeder inlet. By keeping the wire path clean, the Miller 265256 kit reduces downtime associated with equipment maintenance and feed failures.

This kit includes four drive rolls, designed for use in 4-roll wire drive assemblies. The 4-roll system is superior for aluminum applications as it distributes the feeding force over a larger area, allowing for reliable feeding at lower tension settings. This is particularly beneficial when pushing soft wire through longer MIG gun cables. As a genuine Miller OEM product, this kit guarantees compatibility and durability, ensuring your welding operations run smoothly and efficiently.
