I bought a Mitec TIG (Chinese) a few years back.
It worked great until it blew up. Then I couldn't get it repaired in Australia.
So it's still sitting in my shed and doesn't work.
Then I bought a Unimig Tig welder.
It also works great but I can get parts and service in Australia if anything goes wrong with it.
It only cost about 15% more than the Mitec. I wish I'd known that before I wasted my money on the first unit.
