Claim 10:
11. A method, comprising:
receiving, at control circuitry, a flow path pressure measurement of a flow path pressure of a flow path between a first valve and a second valve, the first valve being in fluid communication with a fluid reservoir, and the second valve being in fluid communication with the first valve and a welding tool;
receiving, at the control circuitry, 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:
closing the first valve via a first control signal sent by the control circuitry, and
after closing the first valve, closing the second valve via a second control signal sent by the control circuitry in response to determining, via the control circuitry, the flow path pressure measurement is equal to the ambient environment pressure measurement.
