Doing a tafe course is pretty good because you obvious get instruction and help and pick up tips from guys that have been doing it for a while.
You'll need that list that blaq boi post plus a bench grinder (abit more important for mild steel) for grinding tungstens
angle grinder for cleaning up metal
Finger dexterity is more important with tig than it is with a mig. With gloves most people use something like a rigging glove but you can get gloves that are abit better suited
If you have the money automated welding mask $250-$700
Best to start on mild steel, doing lines on plate no filler rod, lines with filler rod and then doing joins. Once you get the hand skills then go onto aluminum.
You'll need to do abit of reading on tig basics gas types, flow rates, currents, tungsten types, filler rod types, filler rod/tunsten distances/ angles.
