Hi,
Good luck choogh.
There are plenty of teachers here on the forum in fact expert tig welders only too willing to offer advice and answer questions also YouTube videos are a huge help.
I'm still pretty much a novice having suffered just about every problem and mistake possible over the last few months but with help from members and watching videos I can now tig weld aluminium; may I suggest you buy a tig welder and make all the mistakes as many of us have; it saves trying to find a teacher with hands on assistance. Go for it if you're stubborn enough you'll win.
Kind regards, Colin.

I had never tried tig welding until a few months ago but having made all the mistakes I've not only learnt tig welding but also a bit of panel beating and metal spinning to spin the domed ends. Don't try tig welding thin aluminium until you can weld thick aluminium and run lots of practice beads before tackling joints.
