OVERVIEW

Best-in-Class Portability and Performance

Take your welding capabilities anywhere with the Miller Maxstar 161 STL, the ultimate portable solution for DC TIG and Stick welding. Whether you are working on a farm, repairing restaurant equipment, or handling custom fabrication in your garage, this machine delivers professional results in a package that weighs only 13 pounds. The included handle and shoulder strap make it effortless to transport from job site to job site, ensuring you have the power you need exactly where you need it.

The Maxstar 161 STL is packed with features designed to make your life easier. Gone are the days of worrying about input voltage; with Auto-Line technology, you can plug into any 120V or 240V outlet, and the machine automatically adjusts. The separate power cords disconnect easily without tools, adding to the convenience. When it comes to welding performance, this inverter machine shines. It provides excellent puddle control and stable arcs, even on 120V power. Stick welders will appreciate the specialized 6010 mode and Adaptive Hot Start, which makes striking an arc smooth and reliable every time, preventing electrodes from sticking to the work.

This Standard Package includes the power source, both 120V and 240V power cords, a stick electrode holder, and a work clamp. Note that for TIG welding, a TIG torch is sold separately or available in other packages. The machine's built-in gas solenoid means you can use a standard TIG torch without a bulky gas valve on the handle, giving you better control and comfort. Backed by Miller's True Blue 3-Year Warranty, the Maxstar 161 STL is a dependable investment for any welder seeking versatility and quality.

FAQ

No, the Maxstar 161 STL is a DC-only machine. TIG welding aluminum typically requires AC output. This machine is designed for steel and stainless steel.

The Standard Package includes the Maxstar 161 STL power source, 6.5 ft primary cords for both 120V and 240V, a stick electrode holder with 13 ft cable, a work clamp with 10 ft cable, and an adjustable shoulder strap. It does not include a TIG torch.

No, the Maxstar 161 STL uses Lift-Arc technology for TIG starting. This allows for arc initiation without the use of high frequency, minimizing interference with surrounding electronics.

Yes, the Maxstar 161 STL features a specific setting for 6010 electrodes, providing superior arc performance and stability for this difficult-to-run rod type.

No, this machine has a built-in gas solenoid. You can use a TIG torch without a manual gas valve, as the machine controls the gas flow automatically.

The machine utilizes Auto-Line technology and can operate on input voltages ranging from 120V to 240V, single-phase, without manual linking.

At 240V input, the rated output is 160 Amps at 20% duty cycle. At 120V input, the rated output is 90 Amps at 100% duty cycle (TIG) or 60 Amps at 100% duty cycle (Stick).

The unit is extremely portable, weighing only 13 lbs (5.9 kg).
