I have had my smith regulators set up for oxy/propane for about 3
years withno problems. However, I haven’t used them in the last
year, and I recently attached them and did some soldering but my
oxygen tank was hissing. I don’t remember it doing that before. It
seems to be coming from the non-psi dial (Idon’t know what it’s
called, and I’m not sitting in front of it). I have a dual torch set
up; a Meco Midget and a Smith Little Torch. It seems to work fine,
so I don’t know if I should be concerned or not. When I set it up I
didthe spray with soapy water test, and no leaks, but it immediately
started hissing. When I relieve the pressure it goes down, but when
it builds back upagain it comes back.
If it is the regulators, what do I do? I purchased them from Otto
Frei in 2009ish.
