    Natasha, I have worked on many regulators over the years. The problem
    you are have is usually associated with oxygen regulators. The
    problem you are having is usually caused by a faulty valve seat,
    which is located under the diaphragm. It is very rare for Smith
    regulators to have this problem, especially for acetylene. But, if
    you have been laying the tank on its side during use, or even laying
    it on it's side during transport from the place where you get it
    filled, this may cause a problem. Acetylene tanks have a sort of
    antifreeze in them. When they are laid on their side this substance
    soaks into a foam separator that is suppose to keep it out of your
    regulator. This substance is very gooey and can hold the regulator
    seat open and allow the pressure to creep uncontrollably. If you lay
    you tank on it's side during transportation, then let it sit up for
    at least two or three hours before using. Some would, and maybe
    should, recommend a much longer period of time before using. 

    If this does not sound like a possible problem for you, then please
    Email me back or call me at 1 (800) 659-3835. 

Thank you, Steve Santa Fe Jewelers Supply
