Hi Gang,

    I'd have to agree with Don. 

    Look at what it is you're wanting to do, 'turn the torch off'. That
    means putting out the fire. There are 2 ways to put out a fire;
    remove the fuel or remove the oxy. Since there's oxy in the air,
    there's no easy way to remove the oxy. If the torch oxy is turned
    off, the flame will still burn using atmospheric oxy. 

    The best way to turn an oxy/fuel torch off is to turn the fuel off
    1st, then the oxy. 

Dave
