Claim 0:
1. A welding-type system, comprising:
a first valve in fluid communication with a fluid reservoir;
a second valve in fluid communication with the first valve and a welding tool; and
control circuitry configured to:
receive a flow path pressure measurement of a flow path pressure of a flow path between the first valve and the second valve,
receive an ambient environment pressure measurement of an ambient environment pressure, and
in response to detecting an end of a weld, or an end of a postflow operation following the end of the weld:
close the first valve via a first control signal, and
after closing the first valve, close the second valve via a second control signal in response to determining the flow path pressure measurement is equal to the ambient environment pressure measurement.
