951867 - Miller AlumaFeed 450 MPa MIGRunner Package with Water-Cooled XR-Aluma-Pro Gun

Mastering Aluminum Fabrication with the Miller AlumaFeed 450 MPa MIGRunner

The Miller AlumaFeed 450 MPa MIGRunner package represents the pinnacle of industrial aluminum welding technology. Designed specifically for heavy-duty manufacturing environments such as shipbuilding, trailer fabrication, and recreational vehicle production, this system eliminates the common frustrations associated with feeding soft aluminum wire. At the heart of the system is the AlumaPower 450 MPa power source, a dedicated inverter designed to deliver precision arc performance. When paired with the XR-AlumaFeed suitcase feeder, the system utilizes a synchronized push-pull wire feeding mechanism. This ensures that aluminum wire is fed consistently and smoothly, even over long distances, preventing bird-nesting and burn-back that can halt production.

One of the standout features of this package is the inclusion of the XR-Aluma-Pro water-cooled gun. With a 25-foot reach, this gun allows welders to access large weldments without moving the power source. The water-cooling system, powered by the included Coolmate 3, ensures that the gun remains cool even during high-amperage, high-duty-cycle applications, significantly extending consumable life and improving operator comfort. The gun's balanced, ergonomic design reduces fatigue, which is critical for operators welding for extended periods.

Technologically, the AlumaFeed 450 MPa is equipped with Synergic Pulsed MIG capabilities. This advanced process provides a spray transfer-like arc at lower average currents, allowing for welding in all positions with excellent fusion and minimal spatter. The system also features Miller's exclusive Profile Pulse™ technology. This innovation modulates the wire feed speed and amperage to create a "stacked dime" bead appearance similar to TIG welding, but with the speed and simplicity of MIG. This is particularly valuable for visible welds on aluminum boats or trailers where aesthetics are just as important as structural integrity.

Durability is engineered into every component. The Wind Tunnel Technology™ protects internal components from airborne contaminants, while Fan-On-Demand™ operates the cooling system only when necessary, reducing noise and energy use. The entire system is mounted on a heavy-duty MIGRunner cart, providing a mobile, organized station that holds the power source, feeder, coolant system, and gas cylinder securely.
