I am having issues with my regulators. They are single stage Smith
and I purchased them from Rio Grande. I am using oxygene and propane
tanks and a Meco Midget torch. I have flashback arrestors (also from
Rio) installed at the tank.
Here is what I wonder about:
When I am working on bigger pieces I am using a number two tip. I
want to get a nice bushy reducing flame with just a bit of orange
and no hiss. I cannot seem to get this to work. I might get a bit of
orange, but it is always a very long pointy flame cone and the flame
seems to be always hissing, no matter how I adjust the oxygene on
My regulator also seems to be “breathing”. That is what it sounds
like and I also see the oxygene levels appearing to increase and
decrease. At other times the oxygene seems to get higher without me
adjusting it. I might start out with a bit of orange and after a few
seconds I have a much smaller and pure blue flame. I am also
noticing the setting on the propane regulator move up and down as I
use the torch.
When I turn off the tank, then open the torch to bleed the line I
expect the pressure on the regulator to decrease immediately.
Instead it starts to increase significantly before falling. Is that
I am somewhat concerned about using my torch without knowing what is
going on. Can you please help me?
