907420 - Miller AlumaPower 350 MPa Aluminum MIG Power Source

Achieve TIG Aesthetics with MIG Speed

For professional welders who demand the best in aluminum welding, the Miller AlumaPower 350 MPa delivers the perfect blend of productivity and precision. This machine is famous for its Profile Pulse™ technology, which allows you to achieve the coveted "stacked dimes" look of a TIG weld with the simplicity and speed of a MIG process. By modulating the wire feed speed and power, Profile Pulse creates a consistent ripple pattern without the need for complex gun manipulation, helping you produce showroom-quality welds with less fatigue.

Setting up for aluminum has never been easier. The AlumaPower 350 MPa features Synergic Pulsed MIG, which takes the guesswork out of dialing in your machine. Simply select your wire type and diameter, and as you adjust your wire speed, the machine automatically aligns the pulse parameters to maintain the perfect arc. This means you can focus on your travel speed and gun angle rather than constantly tweaking voltage and amperage knobs. The result is a forgiving arc that wets out the puddle beautifully, reducing spatter and post-weld cleanup.

The machine is built to work as hard as you do. With Miller's Auto-Line technology, you can plug into almost any available power source on the shop floor or job site—from 208V to 575V—without opening the case to move jumpers. The lightweight, aerospace-grade aluminum case makes it durable yet portable enough to move around the shop. Plus, the Fan-On-Demand system keeps the noise down, so you can communicate with your team and work in a more comfortable environment.

When paired with an XR-AlumaFeed™ and an XR-Aluma-Pro™ gun, you get a true push-pull system that eliminates the bird-nesting and feeding issues common with aluminum MIG. The trigger schedule select feature allows you to switch between two sets of parameters on the fly—perfect for when you need a hot start or a crater fill at the end of a weld. Whether you are building boats, trailers, or signage, the AlumaPower 350 MPa gives you the control and confidence to lay down perfect aluminum beads every time.
