300264 - Miller XR-A Aluma-Pro 35ft Push-Pull Gun Air-Cooled

Industrial Grade Aluminum Wire Feeding Solution

The Miller XR-A Aluma-Pro 35ft. (300264) is a premium air-cooled push-pull MIG gun engineered specifically for the rigorous demands of industrial aluminum welding. Designed to overcome the common challenges associated with feeding soft aluminum wire over long distances, this system utilizes a synchronized push-pull mechanism that maintains constant tension on the wire, effectively eliminating buckling, bird-nesting, and erratic arc performance. With a substantial 35-foot (10.6 meter) reach, this gun is ideal for large-scale fabrication environments such as shipbuilding, trailer manufacturing, and aerospace applications where equipment mobility is limited.

Technically, the XR-A Aluma-Pro is rated for 300 Amperes at a 100% duty cycle when using 100% Argon gas, ensuring it can withstand continuous operation in high-production settings without overheating. The gun accommodates aluminum wire diameters ranging from .030 to 1/16 inch (0.8 to 1.6 mm). A key engineering feature is the 360-degree rotatable gooseneck, which allows the operator to adjust the torch angle for optimal access to complex joints without straining the cable assembly. The internal design prioritizes ease of maintenance; drive rolls and consumables are easily accessible, and the full-length liner is replaceable, ensuring long-term serviceability and reduced operational downtime.

Integration with Miller's XR-Control systems or compatible power sources (such as the Millermatic 350P Aluminum) provides a seamless welding experience. The gun's robust construction protects internal components from the harsh realities of the shop floor, while the specialized cable materials resist abrasion and kinking. For facilities requiring consistent, high-quality aluminum welds over extended distances, the XR-A Aluma-Pro represents the industry standard in push-pull technology.
