I used to run a TIG while in college but I haven't been able to for hobby uses just because they are just so much more expensive than stick or O/A welding rigs. This obviously isn't intended to compete with a serious TIG unit, but for small jobs it can do pretty well. Obviously you still need an argon tank to supply the shielding, but once you have that you can be up and running. Since this is a small unit, I picked up a small 20cf tank and a valve on amazon (https://www.amazon.com/gp/product/B08LC41FTD). Something to be aware of is that while this is a TIG, it is a DC-only version, so you can't weld aluminum as that requires AC. It does have the ability to run as a stick welder, which is really nice since that opens up the option of taking it along for a lightweight welding rig if you just need to repair something small and don't need the full TIG capabilities. It does also have a "clean" function that uses a wet brush and current to remove an oxide layer off a recent weld pool. I haven't tried that function out, but for certain situations I could see where it could come in handy. Also, while it's a little bit unusual, I really like the 110-220 option. You can do lighter jobs on a normal house outlet, but if you need the full 225amps, then you can use the adapter and plug it into a 220v outlet. With all the options, this easily replaces my little 125a portable welder.
