Hello Shirley, Judy and All,

    The line pressure (left hand gauge) for the acetylene atmospheric
    air torch confused me too. I've owned this torch and sold it for
    many years but it was always with a single gauge regulator telling
    me only the tank pressure, not until recently did Smith Equipment
    start selling it with dual gauges. I have contacted Smith Equipment
    to clarify the proper settings and they recommended that the line
    PSI be set at 12 - 14 for ALL tips on the ACETYLENE ATMOSPHERIC
    torch. Never exceed 15 psi for any acetylene tank.

>     stage regulator". 

    There are two types of regulators most commonly used in our little
    part of the torch world "single stage" and "dual stage" both
    typically have two gauges indicating tank pressure and line delivery
    pressure. The difference between dual stage and single stage is not
    the amount of gauges but the consistency/accuracy in line pressure
    delivery. The dual stage delivering the more accurate consistent
    line pressure, basically two regulators in one. Check out the price
    difference and if you get a chance to look at both close up you'll
    see the dual stage is much bigger in size and cost. 

    Regarding the starting up and shutting down of a torch system.
    Please, please, always follow the manufactures procedures, you'll
    find they match some of the other responses on this forum. 

Sincerely,

Thackeray Taylor
