255338 - Miller XR-Aluma-Pro Water-Cooled Head Tube 45-Degree

Genuine Miller Replacement Head Tube for Water-Cooled Push-Pull Guns

The Miller 255338 Head Tube Assembly is a critical replacement component designed specifically for Miller's high-performance water-cooled push-pull MIG guns. Engineered to fit the XR-Aluma-Pro and XR-Pistol-Pro series, this head tube ensures your equipment operates at peak efficiency during demanding industrial applications. As a genuine Miller part, it guarantees perfect fitment, maintaining the integrity of the coolant flow and electrical conductivity required for precision aluminum welding.

Optimized Geometry and Cooling

This assembly features a 45-degree bend, which is the industry standard for general-purpose welding, offering a balance between ergonomic comfort and access to weld joints. The 4-inch length provides a compact profile, making it easier to manipulate the gun in tighter spaces without sacrificing the distance needed from the arc heat. The integrated water-cooling channels are designed to dissipate heat rapidly, allowing for higher duty cycles and extending the lifespan of your contact tips and nozzles compared to air-cooled alternatives.

Installation and Compatibility

Replacing a damaged or clogged head tube is essential for maintaining weld quality. The Miller 255338 is designed for quick changeovers, minimizing downtime in production environments. It features a rotatable connection on compatible gun bodies, allowing welders to adjust the angle of the neck relative to the handle for reduced wrist strain in out-of-position welding. Whether you are fabricating aluminum trailers, boats, or aerospace components, this head tube restores the original performance of your Miller XR series equipment.
