>     ALWAYS turn off  oxygen(green) first then the gas 


    I asked at a couple of the welding and supply places nearby.   The
    standard recommendation is to turn fuel off, then the oxygen. The
    instructions that came with my most recent set of Smith regulators
    are as follows: 

    Extinguishing torch flame after heating 

    1.  Turn the fuel gas torch valve to the closed position. 
    2.  Turn the oxygen torch valve to the closed position. 

    Shut down the system 

    1.  Turn the oxygen cylinder valve to the closed position. 
    2.  Turn the fuel gas cylinder valve to the closed position. 

    Bleed the system 

    1.  Open the oxygen torch valve 1/2 turn. 

    2.  When the oxygen regulator low pressure gauge indicates "0",
    close the oxygen torch valve. 

    3.  Open the fuel gas torch valve 1/2 turn. 

    4.  When the fuel gas regulator low pressure gauge indicates "0",
    close the fuel gas torch valve. 

    5.  Turn out the oxygen and fuel gas pressure adjusting screws until
    there is absence of spring pressure felt on the pressure adjusting
    screw.
