I should say with TIG the DT, TT and bottom of the ST are usually 0.8mm (or less) at the ends, and the seatstays often thinner. But all the joints have at least one thicker tube involved (except for the small join between the DT and ST). Yes very different from 1/8" or even 1/16". It's below about 1mm that you need another level of precision and heat control not to blow holes. Just needs practice.
