    I don't know how this thread got on pressure requirements to operate
    a torch running on natural gas.  We use natural gas torches.  They
    run on standard city supplied natural gas pressure.  The air supply
    that is used in conjunction with the natural gas creates the
    pressure.  Years ago, soldering shops used soft air pressure from a
    squirrel cage blower, we now use our standard compressed air lines in
    the factory. The torch has two valves to regulate gas and air
    pressure which is necessary to get the correct air/gas mixture.  In
    fact, years ago they called the torches blow pipes where the solderer
    literally blew air from his lungs in one air hose, and had the torch
    connected to the natural city gas with the other rubber line.
