A real multi-process welder, the Miller MultimaticTM 220 AC/DC can do AC (aluminum) TIG welding. Up to 230 amps of MIG welding power and up to 210 amps of TIG welding output are produced by the Multimatic 220 AC/DC. Miller® MDXTM-100 MIG welding gun, WeldcraftTM 150 amp TIG torch with accessories, remote foot control, two argon flow regulators with hoses, stick electrode holder, and ground clamp make up the whole portable MIG, Stick, and AC/DC TIG welding equipment.

Miller’s Auto-SetTM Elite and a color LCD screen are included as standard features with the MultimaticTM 220 AC/DC. You only need to enter the metal thickness and welding wire or tungsten electrode diameter for Auto-SetTM Elite to automatically establish the MIG, Stick, and TIG welding settings. You may manually adjust the weld parameters to fit your own tastes. The patented multi-voltage plug (MVPTM) from Miller allows the 220 AC/DC to operate on either 120 volt or 240 volt input power and weigh only 56 pounds.


Stick, MIG, flux-cored, AC/DC TIG, and multiprocess welding are all possible. Unlike other machines where you need to buy extra accessories, the Multimatic 220 AC/DC comes with everything you need to weld any procedure.
The polarity is automatically determined by QuickTechTM technology. Work is always plugged into the outlet in the lower right corner. Both the MIG gun and the TIG torch can remain attached. The appropriate procedure is switched to automatically. There is no need to manually switch processes; just press the trigger or foot control, and the machine switches. QuickTechTM automatically uses the last process’s parameters.
With the flexibility to fine-tune your settings, Auto-SetTM Elite may be utilized with a variety of materials and procedures. Simple to set up and operate.

Setting weld settings is made easier with Pro-SetTM (TIG and stick manual modes). Simply move the control until the number goes blue and Pro-Set is visible on the display.
Controls the cleaning activity (Pro-Set 75%) is AC Balance (AC TIG).
The width of the arc cone is controlled by AC Frequency (AC TIG) (Pro-Set 120 Hz)

To concentrate the arc for improved stability, penetration, and travel speed, use pulse (DC TIG) (Pro-Set 100 Hz)
Using DIG (Stick) and Pro-Set 30% 7018 electrodes, you may customize arc characteristics for a variety of applications.
The user interface on the intuitive color LCD makes adjusting the parameters quick and simple.


With the help of a multi-voltage plug (MVPTM), you may connect to 120 or 240 V power outlets without the need for any equipment. Simply select the appropriate plug and attach it to the power cable.
Angled wire drive for rapid wire replacements and smooth feeding with Quick SelectTM drive roll.
For dependably smooth, spatter-free MIG starts, use Smooth-StartTM.

There are two shielding gas connectors, allowing both gases to remain connected to the machine without switching. MIG and TIG gas connections are separate.
By only operating when necessary, the Fan-On-DemandTM power source cooling technology lowers noise, energy consumption, and the quantity of pollutants drawn through the machine.
