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.

  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.
