Nice book!
When I was in high school I worked in at body shop (Gateway Body and Fender - which is still in business to this day!) -- and we used to Braze fenders etc on - and I learned to weld with Oxy/Ace torch. Those skills were easily transferred when I started to TIG - because it's a similar hand action. The major difference is with the gas torch - you made a circular motion. But moving the puddle - torch angles - fill feed - those are directly similar.
Back then (45 years ago!) we Stick welded... and that's very similar to MIG welding - you could push or drag the stick.. You learned to bury it in the puddle if you needed the penetration - and how to pick up both sides of an inside corner - or the weave needed for a vertical joint etc. I like not having to chip the slag...
