Default Proper pressures for a Piranha

So I finally got to (briefly) light up my Piranha. I say briefly, because hubby isn't finished with ventilation yet (why is that ALWAYS the last thing to get done - sheesh!) and I didn't want to gas myself to death.

Anyway, I noticed that it was a tad "hissy" at what I thought should be proper O2 and propane pressure, going by the doco. I searched through the Torch section and didn't really see anything that says - "these pressures work really well".

I'm running on O2 TANK and propane. I started at 10 (o2) and 5 - I figured "more is better... right?" and that's at the "top end" of the range. When I couldn't get it to stop hissing, I turned it down to 8 and 4, but could only stop the hissing with a slightly reducing flame, not a neutral flame. At that point, I knew I was inhaling more gases than was healthy, so I quit.

How low should I turn it down? Am I doing something else wrong, that it should really work right at those pressures?

Thanks
