951550 - Miller AlumaFeed 350 Aluminum MIG Welding System with Push-Pull Gun

Industrial Aluminum MIG Welding Solution

The Miller AlumaFeed 350 Welding System (SKU: 951550) is a premier industrial package designed specifically for the rigorous demands of aluminum fabrication. This comprehensive system integrates the AlumaPower 350 MPa power source with the XR-AlumaFeed wire feeder and the XR-Aluma-Pro push-pull gun, creating a synchronized welding environment optimized for soft aluminum alloys. The system is engineered to address the common challenges associated with aluminum GMAW, particularly wire feeding issues and arc instability.

At the core of this system is the AlumaPower 350 MPa, an inverter-based power source featuring Auto-Line™ technology. This allows for connection to any input voltage ranging from 208 to 575 V, single or three-phase, without manual linking, ensuring flexibility across different job sites. The power source provides Synergic Pulsed MIG capabilities, where the operator simply selects the wire diameter and material type, and the machine automatically adjusts pulse parameters to match the wire feed speed. This significantly reduces setup time and ensures consistent weld quality.

The included XR-AlumaFeed unit works in tandem with the 15-foot XR-Aluma-Pro air-cooled gun to deliver a true push-pull feeding mechanism. This design eliminates the friction and buckling often seen when pushing soft aluminum wire through long liners, effectively preventing "bird-nesting" and downtime. The system also features Profile Pulse™, a proprietary Miller technology that modulates the output to create a "stacked dime" bead appearance similar to TIG welding, without the slow travel speed or high skill requirement of GTAW.

This package comes complete with a MIGRunner cart, providing a mobile station for the power source, feeder, and gas cylinder. It is an ideal solution for manufacturing sectors such as boat building, trailer fabrication, and signage, where high-deposition rates and aesthetic weld quality are paramount.
