Apparatus and method for brazing

A brazing system, comprising:

• a first pressure regulator valve to regulate a first pressure of a first gas;
• a second pressure regulator valve to regulate a second pressure of a second gas;
• a first micrometer valve positioned downstream of the first pressure regulator valve, the first micrometer valve configured to control a first flow rate of the first gas;
• a second micrometer valve positioned downstream of the second pressure regulator valve, the second micrometer valve configured to control a first flow rate of the second gas;
• a single enclosure including:
• a first compartment that includes the first pressure regulator valve, the first compartment further including a first inlet to receive the first gas and a first outlet through which the first gas exits, the first pressure regulator valve disposed between and connected to the first inlet and the first outlet, and
• a second compartment that includes the second pressure regulator valve, the second compartment further including a second inlet to receive the second gas and a second outlet through which the second gas exits, the second pressure regulator valve disposed between and connected to the second inlet and the second outlet,
• wherein the first and second compartments are separated by a divider to seal the first compartment from the second compartment such that no gas can transfer between the first and second compartments;
• a brazing torch, having an operating trigger or on/off switch, coupled to each of the first and second outlets;
• and
• a control circuit configured to establish a ratio of flow rates of the first gas to the second gas at the brazing torch using the first pressure regulator valve and the first micrometer valve to regulate a flow of the first gas, and using the second pressure regulator valve and the second micrometer valve to regulate a flow of the second gas.
