Hehe...am I the only one that preferes TIG?
Comparing MIG to TIG is like comparing Crown Vic to 911...
TIG does require some initial skills but boy is it versatile. Once you have "the feel" you can weld whatever you like. Brand new TIG welders are expensive but there are nice used ones that can be bought cheap.
Mattias bought perfectly working Miller 330A for peanuts from nearby shop. I even had water-cooled handle and Argon tube. Only problem is that it weights half a ton

But it can handle aluminium, stainless steel, titanium and all other sorts of difficult materials and deliver up to 450 amps in DC mode.
It's the Rolls Royce of weld-machines. There are (much) small AC/DC TIG designs based on switch/inverter technology on market but they are expensive.
Try to do this with MIG
