Miller Maxstar 161 Sth TIG and Stick Welder (907711)

The Maxstar 161 STH adds TIG to the same compact stick inverter platform, though this version does not include an actual TIG torch, only the air-cooled torch connector. It runs on 120 or 240-volt power and is DC only, so it will not TIG weld aluminum.

Amperage ranges

Stick output runs 20-90A on 120V up to 20-160A on 240V, and TIG output runs 5-130A on 120V up to 5-160A on 240V. It covers roughly 3/16 in of mild steel or stainless on 5/32 in rod, weighing 13 lbs total, light enough to move between benches without a cart.

What you will still need

Because the torch itself is not included, a shop already stocked with an air-cooled TIG torch can plug straight in; everyone else needs to add one separately before TIG work can start. As shipped, the kit pairs the power source with a 6.5 ft cord for each voltage, a stick electrode holder and clamp fitted with Dinse connectors, the torch connector, and a shoulder strap.

Does it come with a TIG torch? No, only the connector; the torch is a separate purchase.

Can it TIG weld aluminum? No, the STH is DC only.

What would need to be added to run TIG? Just an air-cooled torch that matches the included connector; everything else is ready to go.
