For general bodywork, any Mig would work but, I would recomend the 349 dollar lincon welder, it's a good named welder and it's a good price, it's not the biggest/ best welder you could buy but, it would deffenetly do bodywork. it is an 85 amp unit and can weld 1/8" steel. The cambuls hausfeild from Walmart is a 115 unit but, walmart quality ( they force there suppliers to send out products to other contreys for assembly and they use cheaper parts, in the end, the price can be marked up over 50-200% and still be cheaper for the customer ( My mom works at walmart and I watched the walmart haters special on TV.) also, approx 85% of the American population buys an appliance from walmart every year. to give an exzample of walmart quality, look at a Remmington gun pricing book, there is a listing for walmart and a listing for all the normal companys, Walmart listing is much less.
