300265 - Miller XR-W Aluma-Pro Push-Pull Gun 35ft Water Cooled

Industrial Grade Water-Cooled Push-Pull Performance

The Miller XR-W Aluma-Pro 35ft (300265) is a premier solution for heavy-industrial aluminum welding applications. Engineered specifically to address the challenges of feeding soft aluminum wire over long distances, this push-pull MIG gun integrates seamlessly with Miller's XR-AlumaFeed and compatible power sources. The 'W' designation indicates a water-cooled system, which significantly enhances the duty cycle, allowing for continuous operation at 400 Amps with 100% duty cycle using CO2 or mixed gases. This thermal management is critical for high-volume manufacturing environments such as shipbuilding, trailer fabrication, and aerospace components where downtime for torch cooling is not an option.

Mechanically, the XR-W Aluma-Pro is designed for precision and serviceability. It features a 35-foot cable assembly that provides exceptional reach, enabling operators to work on large structures without constantly relocating the wire feeder. The internal drive mechanism works in synchronization with the feeder motor to maintain constant tension on the wire, effectively eliminating the friction and buckling (birdnesting) common in standard push-only systems. The gun accommodates aluminum wire diameters ranging from .030 to 1/16 inch (0.8 to 1.6 mm). Maintenance personnel will appreciate the thoughtful engineering: the drive rolls are easily accessible, and the full-length liner can be replaced quickly, minimizing service intervals and keeping production lines moving.

The gun's construction utilizes durable, impact-resistant materials capable of withstanding harsh industrial environments. The connection points are robust, ensuring consistent electrical conductivity and shielding gas flow. For facilities utilizing pulsed MIG (GMAW-P) processes on aluminum, the stable arc delivery provided by the consistent wire feed speed of the XR-W Aluma-Pro is indispensable for achieving X-ray quality welds.
