ok here is my check list for properly setting up the torch( I get to teach this all the time)

6psi acet
35psi oxy
open acet valve 1/4
adjust acet to just start to break away the tip slightly
then make sure lower valave is open 1 full turn
adjust upper valve to get a neutrel flame
depress cutting valve to check that the mix does not change from neutrel

Then you should be set.

Make sure you have back flow preventors and good luck. oh and remember that when cutting thin metal your torch should be angle approx 30 degrees in direction of travel. with thicker metal you should be 85 degrees direction of travel
