Miller Maxstar 161 STH TIG Stick Welder – 5-160A Amp Range, P/N 907711001

Mechanical pipefitters relying on the Miller Maxstar 161 STH TIG Stick welder package (P/N 907711001) eliminate equipment sourcing delays with a complete high-frequency pulse TIG contractor kit. Sourcing separate TIG torches, gas regulators, foot pedals, and cable adapters wastes billable technician hours on fast-track commercial pipe installations. This complete package bundles the 160-amp dual-voltage inverter with a flexible 150-amp TIG torch, a remote foot pedal control, a gas regulator hose kit, and a heavy-duty stick electrode holder.

The included foot pedal remote gives you stepless current adjustments to start the puddle gently and taper off amperage to prevent crater cracks at the end of pipe runs. High-frequency arc starting lights the arc without touching tungsten to plate, preventing tungsten inclusions on sanitary dairy piping. Auto-Line dual-voltage circuitry accepts 120V or 240V primary power, outputting down to 5 amps for thin stainless sheet or ramping up to 160 amps for structural stick welding.
