Miller Maxstar 161 STL 907710 DC TIG / Stick Welder
A 13 lb inverter power source for DC TIG and stick welding, selected as stock 907710 in the STL configuration. It uses Lift-Arc TIG starting, a built-in gas solenoid and a six-pin remote connection. Output depends on the supply: 120 V permits up to 130 A TIG or 90 A stick, while 240 V supports up to 160 A in either process. Separate primary cords, stick leads and a shoulder strap form the standard package.
