The Miller 079599 Drive Roll Kit is a specialized accessory designed to optimize the feeding performance of soft welding wires, specifically aluminum, in compatible Miller wire feeding systems. This kit features a U-groove geometry, which is distinct from standard V-groove or knurled rolls. The U-groove profile provides a larger surface area of contact with the wire without biting into the metal, which is essential for soft alloys like 4043 or 5356 aluminum. By cradling the wire rather than pinching it sharply, these rolls prevent the deformation (flattening) and shaving that can lead to liner clogging, erratic feeding, and arc instability.
This specific kit is engineered for .047-inch (3/64-inch) wire diameters, a common size for industrial aluminum MIG welding applications. The kit is a comprehensive solution for 2-roll drive systems, containing two drive rolls and one inlet guide. The inclusion of the inlet guide is critical, as it ensures the wire is correctly aligned as it enters the drive assembly, further reducing friction and drag.
The 079599 kit boasts extensive compatibility with legacy and modern Miller equipment. It is designed for use with Millermatic 200, 210, 212, 250, 251, and 252 integrated MIG welders. Additionally, it fits external wire feeders including the 22, 32, and 52 series, as well as the rugged Suitcase Series and Reach wire feeders. This versatility makes it a staple inventory item for shops operating mixed fleets of Miller equipment.
Proper installation of the U-groove rolls is vital for achieving high-quality aluminum welds. Operators should ensure that the drive roll tension is set lower than what is typically used for steel wires to avoid crushing the soft aluminum. The precision machining of the Miller 079599 ensures that even at lower tension settings, positive traction is maintained for consistent wire delivery speed, which is directly correlated to constant amperage and voltage output during the weld.
