32oxy and 7 acet??? thats more like cutting torch pressures. About 5psi
of each is more than enough. In fact, I used Kent "Tinman" Whites method
(I use a meco midget). you open the valves on the torch handle wide
open, then crack the acetylene regulator valve (not the tank valve,
thats already open) until you can feel the acetylne on your cheek, light
it, adjust it, then start turning in the oxygen regulator valve to get
your neutral flame.

Note: point the torch AWAY from your face before lighting!!

Done this way, the gauges on my regulators are pratically on the pins
with hardly any reading at all.
