I have a complete floor pan, a floor rail, and a roll cage project to do on my 280z. I would like to know if a cheap 110v mig welder from harbor freight willdo what i need done, or will it make crappy welds that won't hold at all. I don't have that much money to spend on a good welder, or i would get a mm 180. I would like some suggestions for good reliable cheap welders.
