OK so if I were to buy a tig.. what should I bee looking for. Obviously they must range in quality from cheap crap to horribly expensive

Doesn't that require three phase? or am I reading it incorrectly
Probably cheaper over there, I paid 450 for mine, a 200 amp inverter type, that also does MMA (arc), lovely piece of kit.

Definitely... remember this is for a thirteen year old when he comes in from school... we don't have a three phase equipped workshop.

forget the thin stuff for now get him playing with 3mm with his little mig and once he gets the welds to penetrate and ends up with a neat strong joint then move on. nothing but practice can help. if he starts playing with different types he won't get anywhere just get more dissapointed.

Same idea behind it making a pool then melting the filler into it but a lot faster as the arc melts the metal very quickly

I know you should try it
Its my new fave after using them at uni plus theres no potential risk of an exploding gas canister also found out if you mix acetylene with copper you can make an impact explosive

Tig can be used on any thickness metal. Power plants nuclear pipe is up to 3"thick tig welded.
Mig and stick weld is limited only by the output of the machine, on really thick metals you have to use mulitiple passes
No tig can be used on any metal,also mig and arc. right machine correct filler wire/rod and proper training
Tig is just a heat source you still have to melt the base material, then add the filler material. A good tig welder can weld aliminum foil,but takes years of experience.
welding is just melting the base material and adding a filler material to make a solid piece.
Your son welding sheet metal the thin stuff try to find 6012,or 6013 rod 3/32" dia. that is a sheet metal rod shallow penetrating and amps down to 35-45
