OVERVIEW

Ultimate Portability with the Miller Maxstar 161 STH

Take your welding projects anywhere with the Miller Maxstar® 161 STH TIG/Stick Package. This machine defines "best-in-class" portability, packing 160 amps of DC welding power into a compact 13-pound unit. Whether you are working on a shipboard installation, repairing kitchen equipment, or building a custom project in your garage, the Maxstar 161 STH is designed to go where you go. The included adjustable shoulder strap and rugged X-CASE™ make transport effortless, protecting your investment from the bumps and bruises of travel.

Advanced TIG Features for Precision Welds
Don't let the small size fool you; this welder is loaded with professional features. The "STH" designation means you get High-Frequency starts for clean, non-contact arc initiation, as well as built-in Pulsing capabilities. Pulsed TIG welding allows you to control heat input precisely, making it easier to weld thin stainless steel without warping or burn-through. If you are new to these settings, the Pro-Set™ feature eliminates the guesswork by providing optimized presets, so you can focus on your technique rather than the setup.

Ready for Any Job Site
The Maxstar 161 STH adapts to your power availability with ease. It runs on both 120V and 240V power, using simple swap-out cords that require no tools. Stick welding is just as impressive, with specific settings for 6010 electrodes and Adaptive Hot Start™ to prevent sticking. This package (907711001) comes fully equipped with a fingertip remote control for on-the-fly amperage adjustment, a premium Weldcraft™ TIG torch, and a gas regulator. It is the ultimate grab-and-go solution for the serious welder.

FAQ

The STH model includes High Frequency (HF) arc starting and DC Pulsed TIG capabilities, whereas the STL model only offers Lift-Arc™ starting and does not have built-in pulsing.

No, this is a DC-only machine designed for steel and stainless steel. Welding aluminum typically requires an AC power source.

No, this specific package (907711001) includes the RCCS-6M fingertip remote control. A foot control can be purchased separately if preferred.

The Maxstar 161 STH accepts both 120V and 240V single-phase input power using the included interchangeable power cords.

On 240V input, the rated output is 160 A at 20% duty cycle. On 120V input, it is 130 A at 30% duty cycle.

No, the machine has a built-in gas solenoid, so it automatically controls gas flow. You do not need a torch with a manual valve.

The power source weighs approximately 13 lbs (5.9 kg), making it extremely portable.

Yes, this package includes the Miller X-CASE™ for protection during transport and storage.

  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.

    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.
