OVERVIEW

Take Professional TIG & Stick Welding Anywhere

Meet the Miller Maxstar 161 STH, the ultimate solution for welders who need professional-grade performance in a package that goes wherever the job takes you. Weighing in at a mere 13 pounds, this powerhouse is redefining portability in the welding industry. Whether you are climbing ladders, working in tight mechanical rooms, or moving between job sites, the adjustable shoulder strap and compact design make transportation effortless. But don't let the size fool you—this machine is packed with features that deliver superior arc quality for both TIG and Stick processes.

Versatile Power for Any Location
Never worry about finding the right power hookup again. The Maxstar 161 STH comes equipped with separate 120V and 240V power cords that swap out in seconds without tools. Thanks to Auto-Line™ technology, you can plug into any standard residential or industrial power supply, and the machine handles the rest. It's the perfect companion for maintenance repair, shipboard installation, or farm and ranch work where power sources vary.

Precision Control Made Easy
Struggling with thin materials? The built-in Pulsed TIG feature (up to 150 pulses per second) gives you incredible control over the weld puddle, reducing heat input and preventing warping. If you aren't sure where to start, the Pro-Set™ feature takes the guesswork out of setup, letting you dial in optimal settings instantly. For Stick welding, say goodbye to frustrating starts. The Adaptive Hot Start™ ensures your electrode lights every time without sticking, even with tough 6010 rods. Plus, the built-in gas solenoid means you don't need a bulky TIG torch with a manual valve—streamlining your setup for maximum comfort and efficiency.

FAQ

No, the Standard Package (907711) includes the power source, electrode holder, work clamp, and power cords. It includes a TIG torch connector (273483) but does not include the TIG torch itself. You will need to purchase a TIG torch separately or choose a different package if you require one.

The DC Pulsed TIG feature allows you to pulse the arc between 0 and 150 Hz. This increases puddle agitation and arc stability while significantly reducing heat input, which helps prevent distortion and burn-through on thin materials.

Yes, the Maxstar 161 STH is designed with superior Stick arc performance that specifically supports difficult-to-run electrodes like E6010, making it suitable for pipe and construction applications.

The machine features Miller's Auto-Line technology and comes with two separate power cords (one for 120V and one for 240V). You simply disconnect the cord from the rear of the machine and attach the one you need—no tools or internal linking required.

On 240V input, the rated output is 160 Amps at 26.4 VDC with a 20% duty cycle, or 110 Amps at 24.4 VDC with a 100% duty cycle. On 120V input, it is 90 Amps at 13.6 VDC with a 100% duty cycle.

Yes, the 'STH' in the model name indicates it supports both Lift-Arc™ and High-Frequency (HF) arc starting for TIG welding, allowing for non-contact arc initiation.

No, the Maxstar 161 STH is a DC-only machine. It is excellent for steel and stainless steel but cannot weld aluminum, which typically requires AC output.

Pro-Set eliminates guesswork when setting weld parameters. It provides professionally optimized preset controls for features like Pulse, allowing you to quickly select the best settings for speed and confidence.

  1. Size does not matter with this machine

    Been welding with this machine at my work for a couple years. It doesn't pop breakers like its predecessor. You can actually stick weld without long arching. 220 works much better than 110 but my generator in my feild truck runs this great !

  4. I would defiantly buy this machine again.

    We use this machine for Tig welding food grade milk pipe in our dairy. It works great, and with its small size we can get up into the ceiling to reach pipes needing leak repairs.

  6. Worth the money

    Best little welder I've used. Runs 6010 and 7018 just like my big blue. I've ran a few 309l rods and all have welded great doesn't trip my 20 amp 120v breaker. Easy to use and is convenient for jobs that are next to impossible to get my welding rig into .. great for plant work / mobile welding

  7. Next purchase shall be the maxstar 210 DX

    I use this machine in the sanitary welding field. Very compact and very convenient. It gives great output and can handle heavy use on the daily. The pulse on this machine is very convenient for welding stainless steel Pharaohs that can pull if you don't control your heat. Not with this machine.

  8. Best portable DC Tig unit out there.

    Great little machine for portable work. The machine this small, lightweight, runs on 110 or 220, has HF and miller build quality. What else is there to say.
