hey I'm trying to (as a hobby) do some welding stuff like making a bed bar, sliders or simple things like that. I have a bender but I've never welded. I'm looking at buying a welder. what kind would I buy for simple things like that. I've looked a little and seen all the different ones (mig, arc, and so forth) Maybe someone could point me in the right direction to finding info on the different kinds.
