300782 - Miller XR-15A Pistol-Pro Aluminum Push-Pull Gun 15ft

Miller XR-15A Pistol-Pro Push-Pull Gun (Air Cooled) - 300782

The Miller XR-15A Pistol-Pro (300782) represents a significant advancement in push-pull wire feeding technology, specifically engineered for heavy-industrial aluminum welding applications. Designed to address the common challenges associated with feeding soft aluminum wires, this air-cooled gun provides a robust solution for fabrication environments requiring high duty cycles and consistent performance. With a rating of 200 Amps at 100% duty cycle, the XR-15A ensures that operators can maintain productivity without overheating equipment during extended welding sessions.

Engineered for Durability and Precision

At the core of the Pistol-Pro is a highly durable motor and drive assembly. Miller has improved the torque and drive mechanics to enhance feedability, ensuring arc consistency even over the 15-foot cable length. This design minimizes the risk of wire bird-nesting and burnback, which are frequent issues in aluminum MIG welding. The internal components are constructed to withstand the rigors of industrial use, reducing long-term maintenance costs and downtime. The gun features dual wire tension settings, allowing operators to switch between 4000-series and 5000-series aluminum wires easily, ensuring the optimal pressure is applied for the specific alloy being welded.

Simplified Maintenance and Service

Serviceability is a key focus of the XR-15A design. The gun features a toolless head tube assembly, allowing for quick changes or rotation without the need for external tools. This accessibility extends to the drive assembly, making routine cleaning and drive roll replacement a simple task. Furthermore, the feed cable liner is independently replaceable. This design choice significantly lowers operational costs, as users can replace just the liner rather than the entire feed cable when wear occurs. The 360-degree rotatable head tube further enhances versatility, enabling welders to access tight joints and difficult angles while maintaining proper gas coverage and current transfer.

System Compatibility

The XR-15A Pistol-Pro is designed to integrate seamlessly with Miller's advanced wire feeding systems. It works in conjunction with XR-Controls, XR-AlumaFeed wire feeders, and select power sources such as the Millermatic 252, 350P, and 350P Aluminum. This compatibility ensures that the push-pull synchronization is precise, delivering the best possible solution for aluminum fabrication in industries such as shipbuilding, trailer manufacturing, and railcar construction.
