  • 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 our innovative QuickTech technology, setup and changing processes is even easier.

Quick Tech Image

  • 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.
  • Auto-Set Elite

    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 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 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 or 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.

    Easy-to-understand interface

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


    Multimatic 220 weighs 56 pounds
    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.

    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. 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.

    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
