TIG is fun. I've been learning to weld aluminum recently, with no prior welding experience. Mostly from watching YouTube, but I've gotten a bit of advice from random people I know who know how to weld.
Aluminium welding is somewhat hazardous to my understanding. If I remember from talking with a metal smith in my family, it can give off some pretty noxious fumes. Apparently it can even yield Arsenic and Florine fumes (CDC website mentioned those, among others). Again, if I recall correctly, something like a full-face P100 acid-gas mask is usually enough.
