Maxstar 161 STL TIG Welder
The Miller Electric Maxstar 161 STL is a DC TIG and stick welding machine that runs on 110, 115 or 120 V single-phase power. It suits hobbyists and light-fabrication shops working on stainless steel or mild steel up to 3/16 in thick.
Single-phase 120 V input limits
The unit draws a maximum of 23.16 A at 120 V, so a standard household circuit may trip if other loads share the breaker. Output ranges from 20 A to 160 A for stick welding, and the minimum steel thickness is 0.020 in, ruling out very thin sheet work.
Portable inverter, simple setup
Weighing little and needing only a 120 V outlet, the inverter-based design makes it easy to move between jobs. The main installation issue is ensuring the supply circuit can sustain the peak input current without nuisance tripping.

Questions about this item
Which Maxstar 161 STL version should I pick for 110, 115 or 120 volt supply?
The Maxstar 161 STL runs on single-phase 110, 115 or 120 volt AC at 50 or 60 Hz, drawing up to 23.16 amps at 120 volts, so the same unit covers all three voltages.
What does the 160 amp stick rating mean when I am actually welding?
You can set stick output from 20 to 160 amps, letting you weld steel up to 3/16 inch thick and as thin as 0.020 inch on a standard household circuit.
What does the single-phase 120 volt input cap in practice?
Single-phase 120 volt input limits the machine to 160 amps maximum stick output and 23.16 amps input draw, so it runs on a normal household breaker without special wiring.
