Well the fab section says no questions so:
What does everybody run for cup sizes? What cup sizes do you use for whatever, and is there a cup size that everybody just always uses?
Anybody have a tungsten type and size they stick with? for AC/DC
How much gas do you run? Say your using a smaller cup/bigger cup, or higher amperage, or welding a different material?

I like to run a #6 cup for pretty much all steel but iv only been welding thin stuff around 90 amps so far.
The red (thoriated) is what iv been using lately, 3/32"
around 15 to 20 cfh.

Any tips about tig welding are greatly apreciated, im just trying to get an idea of what everyone else does so I can try new things.
Thanks!
