Wondering what tricks and techniques the experienced tig welders that frequent this forum are using to weld tight spots, like underneath fastback seat stays?
I've heard about the so called 'big white tig cup' but can't seem to find much information about it.
I've seen pictures of perforated copper boxes hooked up to gas, as well as foil wrapped around tube clusters to trap gas.
I've also seen pictures of guys welding with huge cups on tiny torches.
Zank? Tyler? What works for you guys?
