The Miller XR-W Aluma-Pro Plus 25ft (SKU: 300004001) is a premium water-cooled push-pull MIG gun engineered specifically for the rigorous demands of industrial aluminum fabrication. Designed to address the inherent challenges of 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 feeding. This reliability is critical in production environments where downtime directly impacts profitability.
Rated at 400 Amps at 100% duty cycle, the XR-W (Water-Cooled) configuration ensures the gun remains cool even during continuous, high-amperage welding operations. This thermal management not only protects the consumables and internal components but also ensures consistent electrical conductivity for high-quality arc performance. The 25-foot cable assembly provides significant operational flexibility, allowing operators to work on large structures—such as trailers, boats, and aerospace components—without the constant need to reposition the wire feeder or power source.
Maintenance and serviceability are key aspects of the Aluma-Pro design. The gun features tool-less access to drive rolls and tension settings, allowing for rapid changeovers on the shop floor. The head tube is rotatable 360 degrees, providing versatility for complex joint configurations. Compatible with Miller's advanced wire feeders, including the XR-AlumaFeed and select Millermatic systems (with appropriate adapters), this gun represents a top-tier investment for facilities focused on high-volume aluminum welding.
