951838 - Miller AlumaFeed 350 MIG System with 15ft Air-Cooled XR-Aluma-Pro Gun

Industrial Aluminum MIG Welding Solution

The Miller AlumaFeed 350 Welding System (SKU: 951838) represents a dedicated solution for industrial aluminum fabrication, integrating the advanced AlumaPower™ 350 MPa power source with the robust XR-AlumaFeed® SuitCase® feeder and the XR-Aluma-Pro™ push-pull gun. This stationary package is engineered specifically to address the metallurgical and mechanical challenges associated with continuous aluminum welding in sectors such as shipbuilding, trailer manufacturing, and emergency vehicle construction.

At the core of this system is the AlumaPower 350 MPa, which delivers synergic pulsed MIG capabilities. This technology allows for precise control over arc characteristics, significantly reducing heat input and spatter generation. The system features Profile Pulse™, which achieves a TIG-like bead appearance with the travel speed and deposition rates of MIG welding, essential for applications where aesthetic finish is as critical as structural integrity. The power source utilizes Auto-Line™ Power Management Technology, allowing for connection to any input voltage hookup (208–575 V) with no manual linking, ensuring consistent output even if primary power fluctuates.

The included 15-foot air-cooled XR-Aluma-Pro™ gun is a critical component for reliable operation. Unlike standard MIG guns that rely solely on pushing wire, this push-pull system mechanically assists the soft aluminum wire at the contact tip, eliminating the buckling and birdnesting common in long-distance feeding. The gun design allows for easy access to drive rolls and consumables, minimizing downtime during maintenance. This specific configuration (951838) is an air-cooled setup, suitable for standard duty cycles where the complexity and weight of a water-cooled system are not required. It ships with drive rolls and consumables optimized for .035–3/64 inch wire.

Operators benefit from a simplified interface where wire feed speed controls amperage, while the synergic system automatically adjusts voltage to maintain the arc. This reduces the training time required for new operators to achieve code-quality welds. The system also supports parameter window limits, allowing welding engineers to set strict operating ranges to ensure procedure compliance in regulated industries.
