Hi, i am going to take some welding classes at school soon, and i plan on building a very traditional style model A hot rod. What is the best type of welder to use to box, or "Z" a frame? I plan on buying a welder so any brand/model reconmendations would be helpfull. I am in college now so cost is a big concern but i dont want to end up with a POS welder that i regret buying. also where is the first place to start as far as modifying a frame? are there any plans around that will tell me where and what cuts to make?

Thanks for all help,
Chris
