Hello all! I am trying to learn as much as I can about welding before I purchase a welder. I realize I will need one in my hand to learn the most. I'm looking at a lincoln weldpak 3200. Is it the same as the lincoln 135? I like Lincoln because they seem to be the most common. I'll weld mostly light steel. Being in the marine business, I'd like a unit that will weld stainless and aluminum also. I understand that you can't make chicken soup, out of shicken POOP. If somebody feels I am looking at the wrong welder let me know. I'm willing to spend a few bucks to buy a quality unit that will help bridge the learning curve/gap. thanks
