MILLER MULTIMATIC 220 AC/DC WELDER + SPECTRUM 375 PLASMA CUTTER (907757, 907529)

Auto-Set Elite fast and easy predefined settings for multiple materials and processes to help you get welding quickly.


• Available for all processes (MIG, stick, AC TIG, DC TIG) with the ability to fine-tune your settings.

• Set weld parameters by selecting:

MIG – wire diameter and material thickness

Stick – electrode type, diameter and material thickness

AC/DC TIG – tungsten diameter and material thickness

Pro-Set (TIG and stick manual modes)


Pro-set eliminates the guesswork when setting weld parameters. Simply adjust control until Pro-Set appears on the display and the number turns blue.

• AC Balance (AC TIG)—controls the cleaning action (Pro-Set 75%)

• AC Frequency (AC TIG)—controls the width of the arc cone (Pro-Set 120 Hz) • Pulse (DC TIG)—helps focus the arc for increased stability, penetration and travel speed (Pro-Set 100 Hz)

• DIG (Stick)—lets you tailor arc characteristics for a wide range of applications (Pro-Set 30% 7018 electrodes)

Robust, angled wire drive with Quick Select drive roll

for easily changing one wire type/diameter to another. Quick Select drive roll offers three grooves; two for different size solid wires and a third for flux-cored wire.

Two shielding gas connections

so both gases can be left connected to the machine; no switching needed. One connection for MIG gas and one for TIG gas.

Easy-to-understand interface

with 3.5-inch color LCD display and intuitive connection setup images.

Weighing only 56 pounds

, the Multimatic 220 AC/DC can go where the work is, plus the added convenience of one machine versus two or more.

Operates on 120-volt or 240-volt

power letting you work virtually anywhere. Multi-voltage plug (MVP) easily connects to common 120-volt or 240-volt power outlets (no tools required to change). Choose the plug that fits the receptacle and connect it to the power cord.

14-pin controlled operator alternatives


The standard 14-pin connector on your Multimatic 220 AC/DC lets you choose your control for a customized experience, whether it’s a foot control, fingertip control, or wireless foot control.
