951459 - Miller AlumaFeed 450 MIGRunner Package with 25ft XR-Aluma-Pro Air-Cooled Gun

Industrial Aluminum Welding Solution

The Miller AlumaFeed 450 MIGRunner Package (951459) is a dedicated industrial system engineered specifically for high-performance aluminum welding. At the core of this package is the AlumaPower 450 MPa power source, capable of delivering 450 amps at 100% duty cycle, ensuring continuous operation in heavy manufacturing environments without thermal shutdown. This system is paired with the XR-AlumaFeed wire feeder and the XR-Aluma-Pro air-cooled push-pull gun, creating a synchronized feeding loop that eliminates the common issues associated with feeding soft aluminum wire over long distances.

Technologically, the system features Miller's advanced Synergic Pulsed MIG capabilities. This allows the power source to communicate directly with the wire feeder; when the operator adjusts wire feed speed, the machine automatically adjusts the pulse parameters to maintain a stable arc. This significantly reduces setup time and training requirements. Additionally, the Profile Pulse™ feature modulates the current to create a "stacked dime" bead appearance similar to TIG welding, but with the speed and deposition rates of MIG. The package comes fully assembled on a MIGRunner cart, providing a mobile, turnkey solution for fabrication shops.

Technical Specifications & Compatibility

The system requires 3-phase input power (typically 230/460V) and is designed for heavy-duty applications such as truck and trailer manufacturing, shipbuilding, and railcar construction. The included 25-foot XR-Aluma-Pro gun is air-cooled, reducing maintenance complexity compared to water-cooled systems while still handling substantial amperage. The feeder supports standard aluminum wire diameters including .035" and 3/64", with drive rolls included. The Parameter Window Control feature allows supervisors to lock parameters within a specific range, ensuring adherence to WPS (Welding Procedure Specifications) and quality control standards.
