Miller Multimatic 235 Multiprocess Welder (907780)

Rated at 235 amps, this Miller inverter is built for light manufacturing and fab shops that need a workhorse that sets up fast and can either mount on running gear for moving around the floor or disconnect for working in a tight corner.

What it welds

Processes on tap are MIG, flux-cored wire, stick with a DC lift-arc start, and pulsed DC TIG, spanning beginner through career-welder skill on home, hobby, industrial, and light-industrial jobs. Auto-Set Elite loads predefined settings so a newer operator gets a clean bead without dialing in parameters from scratch.

Before you order

The bare power source weighs 63 pounds and accepts 208 to 240V input. Duty cycle sits at 60 percent across MIG, stick, and TIG at their rated amperages, so factor that into long continuous passes rather than short tack welds. The MDX-250 gun uses Acculock consumables that lock in with a single turn, and the drive system takes a 12-inch spool so roll changes happen less often on a long shift.

Hardware in the box

Standard equipment includes the 7-foot power cord (no plug attached), the MIG gun and cable set, two work leads, a gas regulator, spare tips, reversible drive rolls, and a thickness gauge. Optional running gear and a four-program EZ-Select gun are sold apart from this listing for shops that want them.

What input voltage does it need? Anywhere from 208 up to 240V.
