Apparatus and method for brazing

A brazing gas flow control device, comprising:

• a single enclosure having a first compartment and a second compartment which are separated by a divider in the enclosure, where
• the first compartment has a first inlet through which a first gas is directed and a first outlet through which the first gas exits the first compartment, and where the first compartment contains a first pressure regulator valve, a first micrometer valve positioned downstream of the first pressure regulator valve, and tubing to couple the first inlet, the first pressure regulator valve, the first micrometer valve, and the first outlet to allow for the first gas to be directed through the first compartment;
• and
• the second compartment has a second inlet through which a second gas is directed and a second outlet through which the second gas exits the second compartment, and where the second compartment contains a second pressure regulator valve, a second micrometer valve positioned downstream of the second pressure regulator valve, and tubing to couple the second inlet, the second pressure regulator valve, the second micrometer valve, and the second outlet to allow for the second gas to be directed through the second compartment.
