951841 - Miller AlumaFeed 350 MPa Aluminum MIG Welding System with 30ft XR-Pistol

Advanced Aluminum Welding Solution

The Miller AlumaFeed 350 MPa MIGRunner with 30ft XR-Pistol (951841) is a dedicated industrial system engineered specifically for the rigors of aluminum fabrication. This package integrates the AlumaPower 350 MPa power source with the XR-AlumaFeed Suitcase wire feeder, delivering a synchronized push-pull feeding performance that eliminates common aluminum wire feeding issues. The system features Auto-Line Power Management technology, allowing for connection to any input voltage from 208 to 575 V, single or three-phase, without manual linking, ensuring operational flexibility across various job sites.

Synergic and Pulsed MIG Technology

At the core of this system is its advanced synergic capability. The AlumaPower 350 MPa utilizes built-in pulsed MIG programs tailored for commonly used aluminum alloys, such as 4000 and 5000 series, and wire diameters up to 1/16 inch. The Synergic mode simplifies operation by allowing the welder to adjust wire feed speed while the machine automatically optimizes voltage and amperage. Furthermore, the Profile Pulse feature allows operators to achieve a "stacked dime" weld bead appearance without the need for complex gun manipulation, significantly enhancing the aesthetic quality of the weld while maintaining the high deposition rates associated with MIG welding.

Reliability and Control

The included XR-Pistol Pro air-cooled gun offers a 30-foot reach, providing excellent access to large weldments in shipbuilding, trailer manufacturing, and aerospace applications. The gun is designed with a balanced, ergonomic grip to reduce operator fatigue during extended use. Internally, the power source employs Wind Tunnel Technology to prevent particulate matter from damaging sensitive components, while the Fan-On-Demand cooling system operates only when necessary, reducing noise and energy consumption. With SharpArc technology, operators gain total control over the arc cone shape and puddle fluidity, allowing for precise adjustments from a stiff, penetrating arc to a wider, more fluid puddle.
