As I am intending to buy a mig,and did contemplate a 200amp,but that now is out of the window because of power supply methods,phase 1/3. So,it has to be a 150amp mig. I'm hoping to weld a wing onto a car. And fabricate a new turbo manifold,by welding 2 weld elbows being 3mm thick onto a 10mm plate. Will the power from domestic mains create a good enough result,working with the lowest settings? thanks
