The Miller XR-A Aluma-Pro 25ft. (300001) is a premium air-cooled push-pull MIG gun designed specifically for the rigorous demands of industrial aluminum welding. Engineered by Miller Electric, this gun addresses the common challenges associated with feeding soft aluminum wire over long distances. By utilizing a synchronized push-pull motor system, the XR-A Aluma-Pro ensures consistent wire delivery, virtually eliminating wire buckling, birdnesting, and erratic arcs that plague standard push-only systems.
Built for heavy-duty applications, the XR-A Aluma-Pro is rated at 300 Amps at 100% duty cycle using mixed gases. This high duty cycle allows for continuous welding operation without the risk of the gun overheating, making it ideal for manufacturing environments such as shipbuilding, trailer fabrication, and sign manufacturing. The 25-foot cable assembly provides significant reach, allowing welders to move around large workpieces without constantly relocating the wire feeder.
Miller has prioritized operator comfort and accessibility in the Aluma-Pro series. The gun features a 360-degree rotatable tube, which can be adjusted without tools, allowing the welder to position the gooseneck at the optimal angle for accessing difficult joints. The handle is ergonomically contoured to reduce hand fatigue during extended use, and the trigger hold feature further alleviates strain on long weld runs. Additionally, the gun allows for toolless access to the drive rolls and a replaceable feed cable liner, simplifying maintenance and reducing downtime on the shop floor.
This gun is compatible with Miller's XR-AlumaFeed systems and select Millermatic machines equipped with XR compatibility. It supports a wide range of aluminum wire diameters from .030 inches to 1/16 inches (0.8 to 1.6 mm). The tension setting is easily adjustable via a lever on the gun, ensuring the correct pressure is applied to the wire without deformation. For professionals seeking a reliable, durable, and high-performance solution for aluminum MIG welding, the XR-A Aluma-Pro is the industry standard.
