After some fussing about, I finally started to fill my tanks with Nitrox. The compressor is a RIX-SA3 and I'm having to continually adjust the O2 needle valve to hold things close to my desired 32% O2.
My O2 regulator only provides a PSI gauge on the inlet to the blending stick, and when O2 is flowing it only shows 0 PSI (not a surprise since there isn't any backpressure on the compressor intake). I have an Argon/Nitrogen valve on my MIG welder that I can use to control the volume of gas (cu ft/min) but I've not been able to find an O2 rated regulator that does this.
Is this just the way things are, or should I keep looking for a better O2 regulator?
Many thanks!!
