-
Automatically recalls the settings from the last process used.
Color LCD with Auto-Set Elite

-
Available for all processes (MIG, stick, AC TIG, DC TIG) with the ability to fine-tune your settings.
-
Set Parameters by selecting: MIG - wire diameter and material thickness Stick - electrode type, diameter and material thickness AC/DC TIG - tungsten diameter and material thickness.
- User friendly 3.5-inch color LCD display with intuitive connection setup images.
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 100Hz)
-
DIG (Stick) - lets you tailor the arc characteristics for a wide range of applications (Pro-Set 30% 7018 electrodes)
Robust, angled wire drive with Quick Select Drive Roll
Wire drive system designed 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
Two connections so both gases can be left connected to the machine, no switching needed. One connection for MIG gas and one for TIG gas. The Miller Dual Cylinder Rack Cart (951770) can also be purchased separately to conveniently hold both cylinders.
Portable
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. Handles on the top allow the machine to be easily moved around the shop or garage.
Versatile - Operates on 120V or 240V Power
The Multi-voltage plug (MVP) easily connects to common 120-volt or 240-volt power outlets — no tools required.
Simply 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.
