I know very little about welding. Is there a welder that can do stick and tig? I’ve heard stick is the easiest to do, so I should probably start out with that and practice that first? Does it take a lot of skill to doTIG welds on thin metal like on a AK or PPS43? I have a friend that knows how to TIG weld, does it at work using sheet metal I believeI have found Tig is easier than Mig for me to draw a bead. The best way to learn to weld is grab two pieces of metal and stick them together.
As for equipment recommendations, you cant go wrong with a Miller.
