_I'm looking for a small welder to do some small autobody on some projects coming up. I only need it so big so where does it go through that thick of metal. Basically the body of a car is about as thick as I need to go. I know people would tell me that I should just go big or go home but I truly do not need that big of a welder right now. I'm doing autobody fixes and I don't need that big of a welder to be honest.
