Saturday I was heating up the foot pegs on my 3-wheeler in order to bend them back straight and the flame on my oxy/acetylene kept going rich and I would have to adjust it every once in a while. Also, I could not turn the flame up as high as I would have liked due to insufficent oxygen pressure.

Later, I went to cut some plate and while setting up the pressures I would hit the oxygen lever and gas would come out at the proper rate (by sound) but it would quickly drop down to a whisper and the pressure would drop to zero. When I let off the lever the presure would build back up to 10-15 psi. Also, when I shut the tank valve for the oxygen and bleed off the presuure in the regulator the tank pressure gage still shows 800 psi unless I keep the oxygen on at the torch and then it slowly bleeds down.

It would seem like I do not have any oxygen left except the tank pressure gage reads 800 psi. It is a Harris 2-stage regulator. Any ideas? Otherwise I'll swap out the tank and see if that helps.

Thanks,
