The Miller Multimatic 220 AC/DC Multiprocess welder is a hobbyist and small shop’s dream! Provides the freedom to weld any process; MIG, Flux-Cored, Stick, and AC/DC TIG – with one portable, powerful welder. Demonstrates excellent arc quality on both 120 or 240 Volt power! Setup and switching processes is fast and easy!
All in One
Take on more projects with one machine that has MIG, DC stick, and AC/DC TIG!
MIG: 24 ga. – 3/8″ Steel 18 ga. – 3/8″ Aluminum
DC Stick: 16 ga. – 3/8″ Steel
AC/DC TIG: 24 ga. – 1/4″ Steel and Aluminum
Easy to Use
With the innovative QuickTech technology, setup and changing processes is even easier.
Automatically determines the polarity. Work is always connected to the bottom right receptacle. MIG gun and TIG torch can stay connected at the same time.
Automatically switches to the right process. Just hit the trigger or the foot control and the machine automatically changes, eliminating the need to manually change processes.
Automatically recalls the settings from the last process used.
Color LCD with Auto-Set Elite
Auto-Set Elite can be used on multiple materials and all processes with the ability to fine-tune your settings. Simple to set up and use.
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.
Dependable Arc Starts
Provides High-Frequency, non-contact arc starting to eliminate tungsten and material contamination time after time.
Wide range of TIG adjustability
AC Balance – adjustable from 60-80%
AC Frequency – adjustable from 60-150Hz
DC Pulse – adjustable from Off – 150 pulses per second (PPS)
TIG Post-Flow – adjustable from Auto – 25 seconds
Lift-Arc and high frequency starts
Tungsten size selection
Generator Compatible
The Multimatic 220 will be able to operate and provide full output when powered by generators with 10,000 Watt (10K) output or higher.
Pairs perfectly with generators such as the Miller Bobcat or Trailblazer series. Limited output will occur when used with smaller generators.
Fan-On-Demand
The units cooling system operates only when needed to reduce noise, energy consumption, and limit the amount of contaminants pulled through the machine. It also features built in Thermal Overload Protection to power the machine down if the airflow becomes blocked or the duty cycle is exceeded.
6010 Stick Electrode Capability
Superior Stick arc performance even on the difficult-to-run electrodes like E6010.
