The average person's impression of how metal is welded is that you simply fire-up a blow torch and run it along the edge of a metal seam to weld it together. Or they probably think you can just run that same torch across any kind of metal and cut through it, like in the safe-cracker movies. But the reality of good starter tig welder is that professional welding actually involves some fairly extensive knowledge, and is somewhat of an art form that takes many years of experience to master. Even so, if you are wanting to learn, you can start with a few simple techniques. Once you've mastered the basics and have a beginner's idea, you can then move on to the more complicated skills that take longer to master.
