907420001 - Miller AlumaPower 350 MPa Aluminum MIG Welder System

Master Aluminum Fabrication with Miller

Take your aluminum welding projects to the next level with the Miller AlumaPower 350 MPa, a powerhouse MIG welder designed to deliver TIG-quality aesthetics with the productivity of a wire feed system. If you are in boat building, trailer manufacturing, or heavy fabrication, this machine is built to solve your biggest headaches. The AlumaPower 350 MPa removes the guesswork from aluminum welding with its Synergic Pulsed MIG capabilities. Simply set your wire speed, and the machine automatically adjusts the pulse parameters to give you a stable, spatter-free arc that digs when you need it and wets out perfectly.

One of the standout features for professional fabricators is Profile Pulse™. This technology allows you to achieve that classic "stacked dimes" look without any complex gun manipulation. You can adjust the frequency of the pulse to tighten or widen the ripple spacing, giving your finished welds a show-quality appearance that customers love. The system is also incredibly rugged, featuring a lightweight, aerospace-grade aluminum case that stands up to shop abuse while keeping the unit portable enough to move around the floor. With a weight of just 80 lbs, it packs a massive 425-amp punch in a compact footprint.

Setup is faster and easier than ever thanks to the Auto-Line technology, which lets you plug into almost any shop power (208V to 575V) without opening the case to move jumpers. The machine handles the power management for you, ensuring a smooth arc even if your shop's power fluctuates. Combined with features like Hot Start for eliminating cold starts and Crater fill for preventing termination cracks, the AlumaPower 350 MPa gives you total confidence from the moment you pull the trigger to the moment you finish the weld. This unit comes equipped with auxiliary power, making it ready for water-cooled gun setups to keep you welding longer comfortably.
