Can you recommend me a mig welder?

Since your asking the Question I'm going to assume your not a seasoned welder...that being said, Miller makes a 140 welder with auto set...which is great for standard welding just set one knob to the Auto setting and the other to the thickness of metal and go. Avoid the cheap welders if your serious about welding over the long term. Spend a little more once and never worry about it again.
