Miller Alumapower 450 Mpa MIG Welder with Feeder, 25-FT XR Gun, MIG Kit, and Cart (951840)

This AlumaPower package bundles a 450 MPa MIG power source with its matched XR-Alumafeed suitcase feeder, a 25-foot XR-A Aluma-Pro push-pull gun, a MigRunner cart, a 4/0 MIG industrial kit, and the suitcase mounting bracket, so the pieces are already matched rather than assembled from separate listings. It is a DC MIG-only machine rated for three-phase power at 230, 460, or 575 volts.

Built around aluminum

Miller's push-pull gun design is what makes soft aluminum wire feed reliably over a 25-foot gun length, where a standard feed roller alone tends to bird's-nest the wire before it reaches the torch. The package also covers mild steel and stainless, so the same feeder and cart can switch material without a full equipment change, just a gun and liner swap.

These packages are made to order, so plan on a lead time of two to three weeks before shipment rather than next-day delivery. The whole feeder and cart combination weighs 122 lbs, and Miller covers the package with a manufacturer's warranty.

Is this package MIG only? Yes, it is built around the MIG process, with the push-pull gun specifically for aluminum wire. How long is the lead time? Miller builds these to order, so expect roughly two to three weeks before it ships.
