hello everyone,

tried searching but didn't run into the answer that i was looking for, hopefully someone can help me or point me in the right direction . I would appreciate it in advance !
I just purchased my first tig welder and with it included a brass regulator that reads out SCFM
I was wondering what i should set this at ? I believe the increments are in 10 psi all the way up to 50.

also what are you guys setting your pre and post flow at ?
