300757 - Miller XR-25W Pistol Plus Push-Pull MIG Gun, 25ft, Water-Cooled

High-Performance Aluminum Welding Solution

The Miller XR-25W Pistol Plus is a dedicated water-cooled push-pull gun engineered specifically for heavy industrial aluminum fabrication. Designed to interface seamlessly with the 74 MPa Plus wire feeder, this system provides a robust solution for the inherent challenges of feeding soft aluminum wires over long distances. By utilizing a synchronized motor in the gun handle, the XR-25W eliminates wire buckling and bird-nesting, ensuring consistent delivery even with difficult 4000 and 5000 series alloys. The water-cooled configuration enables a robust output rating of 400 Amps at 100% duty cycle, making it ideal for continuous manufacturing environments such as shipbuilding, trailer fabrication, and sign manufacturing.

Engineered for Reliability and Maintenance

Maintenance and downtime are critical factors in industrial operations. The XR-25W addresses these with a modular design that simplifies serviceability. The feed cable liner is independently replaceable, meaning operators can swap out a worn liner without discarding the entire feed cable assembly—a significant cost-saving feature. Furthermore, the internal components are isolated and designed for longevity, while the toolless head tube removal allows for rapid changes or routine cleaning. The gun features dual wire tension settings, allowing technicians to precisely calibrate the feed pressure based on the specific rigidity of the aluminum alloy being used, thereby optimizing arc stability and weld quality.

Versatile Configuration

Flexibility in the field is achieved through the gun's adaptability. It supports a wide range of wire diameters from .030 to 1/16 inch for aluminum and up to .045 inch for hard wires. The 25-foot cable length provides ample reach for large assemblies, while the availability of over 30 different styles of threaded, quick-change 360-degree rotatable head tubes ensures that even the most geometrically complex joints are accessible. This unit represents a strategic investment in efficiency for operations utilizing the 74 MPa Plus platform.
