Hi im looking for a good mig welder i have to do some repairs to my jeep with a 351w engine and i am making custom exhaust. Can anyone recommend any good cheap welders? i'm looking for something under or around 200. I have a brasing torch and a stick welder but i heard mig welders are the best for exhaust and i need a 120v which i dont have. Anyone know whats the best and is anyone selling their old welder or know some good brands? maybe campbell hausfield? thanks
