Miller Multimatic 215 Auto-Set Multiprocess Welder (907693)

Switching between MIG, TIG, and stick from one inverter, Miller's Multimatic 215 Auto-Set Multiprocess Welder (907693) suits a shop that does not want three separate machines taking up floor space. It plugs into 120V or 240V outlets without tools, and it is rated for aluminum, mild steel, and stainless steel.

Who it is aimed at

Marketed to light-industrial users spanning the weekend welder stepping up to the career welder who needs portability, it keeps gas lines for both MIG and TIG connected at once through a dual-solenoid design, so changing processes is a setting change rather than a hose swap. A color interface walks through setup for whichever of the three you select, and Auto-Set Elite still allows manual fine-tuning on top of its predefined starting points.

Points to confirm before ordering

Match your available circuits against the 120V/240V plug options before buying. The control board figures out on its own which type of gun — standard MIG or spool — has just been plugged in, so there is no manual switch to flip, and the unit cuts power on its own if its airflow gets blocked or you push welding past the duty cycle it is rated for, so give the cooling fan room to work on a bench rather than tucked against a wall.

In the carton

Expect a cord carrying both voltage plugs, a MIG gun and cable set, an electrode holder, a work lead with clamp, a regulator and hose, wire with spare tips, a drive roll sized for multiple wire diameters, and a material thickness gauge.

Can settings be adjusted manually instead of using Auto-Set? Yes, Auto-Set Elite gives starting points by material and process, with room to fine-tune from there.

Miller covers this new unit for 3 years.
