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, wherein the brazing torch does not include any flow control metering valves positioned on the brazing torch for adjustment of the first gas and the second gas;
• 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.
