I own a cheap 110v welder. Its a fluxcore/no gas wire feed. Its not from harbor freight, but from tractor supply company. For $129, I love it. It really doesnt put down a bad weld. With a little practice, you can make really clean welds as good as with gas mig welder. And I stand by that. I wouldnt build a cruiseliner with it... but for exhaust and minor supports and stuff... its great. The biggest issue is that the cheaper welders dont have as much voltage control as a better gas mig. My lincoln 125 has 5 voltage settings and can go pretty low on gauge steel. My cheap welder can only go as low as 16 gauge mild, and that is asking a lot. That takes practice... and patience to not over heat the material... otherwise you just burn through. It was a challenge to mate stainless to mild as well.. yes I did that. stainless headers needed to be extended for a connection.
Then again... If I worked for a shop, I would have invested in a much nicer welder.
