951840 - Miller AlumaFeed 450 MPa MigRunner Package with 25ft Air-Cooled Gun

Precision Aluminum Welding System

The Miller AlumaFeed 450 MPa MigRunner (951840) represents the gold standard in industrial aluminum welding solutions. Designed for heavy-duty manufacturing, shipbuilding, and aerospace applications, this package combines the advanced control of the AlumaFeed 450 MPa wire feeder with the ergonomic precision of the XR-Aluma-Pro air-cooled push-pull gun. The system is engineered to deliver consistent, premium feeding performance, eliminating the common frustrations associated with feeding soft aluminum wires over long distances.

At the heart of this system is Miller's Profile Pulse™ technology. This feature allows operators to achieve the distinct "stacked dimes" appearance of TIG welding while maintaining the high travel speeds and productivity of MIG welding. By modulating the wire speed and power, Profile Pulse creates a consistent ripple pattern without the need for complex gun manipulation. This is ideal for visible welds on boats, trailers, and architectural aluminum where aesthetics are as critical as structural integrity.

The included XR-Aluma-Pro gun features a balanced, ergonomic design that reduces welder fatigue during long shifts. Its industrial-quality cable covering resists damage in harsh shop environments, while the synchronized push-pull motor system ensures wire is delivered smoothly from the feeder to the puddle. The entire setup is mounted on a rugged MigRunner cart, providing portability and organization for your welding cell. With Synergic Pulsed MIG, the system automatically adjusts pulse parameters as wire speed changes, ensuring optimal power delivery without constant manual tuning.

Note: This package requires a compatible power source, such as the Miller AlumaPower MPa series, to function as a complete welding system.
