907711001 - Miller Maxstar 161 STH TIG/Stick Welder with Remote & X-Case

Miller Maxstar 161 STH TIG/Stick Welder Overview

The Miller Maxstar® 161 STH (907711001) is a premier DC TIG and Stick welding solution designed for industrial applications requiring extreme portability without sacrificing performance. Weighing in at just 13 lbs (5.9 kg), this inverter-based power source offers a versatile amperage range of 5 to 160 A, making it suitable for a wide variety of materials, from thin gauge stainless steel to heavier mild steel components. The unit is engineered with Miller's advanced technology to support both 120V and 240V input power, utilizing separate disconnectable power cords that allow for easy switching between power receptacles without tools.

This STH model distinguishes itself with advanced TIG capabilities, including DC Pulsed TIG (0–150 Hz) which enhances arc stability and puddle control while minimizing heat input and distortion on thin materials. It features both High-Frequency (HF) arc starting for non-contact ignition—preventing tungsten contamination—and Lift-Arc™ starting for environments where HF interference must be avoided. The Pro-Set™ feature further streamlines operation by offering factory-preset parameters for Pulse and other settings, allowing operators to weld with confidence and speed.

For Stick welding, the Maxstar 161 STH delivers superior arc performance, even with difficult-to-run electrodes like E6010. The Stick-Stuck feature enhances safety and consumable life by detecting if an electrode is stuck to the part and automatically cutting welding output. This package is a complete contractor solution, including the RCCS-6M fingertip remote control, Weldcraft™ A-150 TIG torch, X-CASE™ for protection, and all necessary leads and regulators, ensuring you are ready to weld right out of the box.
