Miller Maxstar 161 STH TIG Welder 120V

The Miller Maxstar 161 STH is a DC TIG and stick welder that runs on single-phase 110, 115 or 120 V AC at 50 or 60 Hz. It draws a maximum input current of 23.16 A at 120 V and delivers a stick welding range from 20 A to 160 A. The unit handles steel and stainless steel from 0.020 in up to 3/16 in thick.

Suited for light fabrication

This machine suits workshops and mobile technicians who need a portable 120 V supply and fine low-amperage control down to 20 A for thin stainless or steel. Builders who require three-phase input, AC output for aluminium, or material capacity beyond 3/16 in should look at a different class of equipment.

120 V single-phase input with 23.16 A maximum draw

The decisive specification is the 120 V single-phase supply rated at 23.16 A maximum input current, which determines whether your shop circuit can support the welder without an electrical upgrade.

Questions about this item

Should I choose the 110 V, 115 V or 120 V input for the Maxstar 161 STH?

The welder accepts 110, 115 and 120 V single-phase supply automatically; plug it into whichever voltage is available on site.

What does the 160 A stick welding maximum mean when I am actually welding?

It delivers up to 160 A for stick electrodes, letting you weld steel up to 3/16 in thick; minimum output is 20 A for thin material down to .020 in.

What does the 23.16 A input at 120 V tell me about the circuit I need?

At 120 V the unit draws 23.16 A, so the supply circuit and breaker must be rated for at least that continuous current.
