1. A gas manifold operable to provide an uninterrupted supply of gas, comprising:

  • a first gas supply that serves as an online gas supply;

    a first gas inlet operable to receive the first gas supply having;

    a first pressure transducer that senses the pressure of the gas at the first gas inlet; and

    a first regulator operable to regulate the pressure of the gas supplied by the first gas supply;

    a second gas supply that serves as a reserve gas supply;

    a second gas inlet operable to receive the second gas supply having;

    a second pressure transducer that senses the pressure of the gas at the second gas inlet; and

    a second regulator operable to regulate the pressure of the gas supplied by the second gas supply;

    a control valve connected to the first and second gas inlets and to a gas outlet; and

    a microcontroller based control circuit that provides a control signal to the control valve based on signals from the first and second pressure transducers, wherein the circuit directs that the reserve gas supply be placed online when the pressure monitored by the second pressure transducer rises above an electronically established preset level.
