Miller Multimatic 220 AC/DC Welder + Spectrum 375 Plasma Cutter (907757, 907529)
Download Product Spec Sheet
The Miller Multimatic 220 AC/DC Multiprocess Welder (907757) is set to disrupt the market with the combination of MIG, Stick, AC/DC TIG, and Miller's unparalleled reliability and craftsmanship. Building off the success of their multimatic welders, Miller has combined AC capabilities for TIG with their trusted MIG/Stick technology. That means now you only need one machine for all the welding processes and all the metals.
Take on more projects with one machine that has MIG, DC stick, and AC/DC TIG.
• MIG:
24 ga.–3/8 in. steel
18 ga.–3/8 in. aluminum
• DC Stick:
16 ga.–3/8 in. steel
• AC/DC TIG:
24 ga.–1/4 in. steel and aluminum
The Multimatic 220 AC/DC comes equipped with all accessories to weld any process, unlike other machines where you need to purchase additional accessories.
With Miller's 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.
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.
