Apparatus and method for brazing

1. A brazing system, comprising:

a first gas source which provides a first gas and a second gas source which provides a second gas;

a single enclosure having a first compartment and a second compartment which are separated by a divider in the enclosure, where

said first compartment has a first inlet through which said first gas is directed and a first outlet through which said first gas exits said first compartment, and where said first compartment only contains a first pressure regulator valve with a pressure gauge attached thereto, a first micrometer valve positioned downstream of said first pressure regulator valve, and tubing to couple said first inlet, said first pressure regulator valve, said first micrometer valve, and said first exit to allow for said first gas to be directed through said first compartment; and

said second compartment has a second inlet through which said second gas is directed and a second outlet through which said second gas exits said second compartment, and where said second compartment only contains a second pressure regulator valve with a pressure gauge attached thereto, a second micrometer valve positioned downstream of said second pressure regulator valve, and tubing to couple said second inlet, said second pressure regulator valve, said second micrometer valve, and said second exit to allow for said second gas to be directed through said second compartment;

a brazing torch having an operating trigger coupled to each of the first and second exits,

wherein said first pressure regulator valve and said first micrometer valve are the only flow control metering devices used to control a flow rate of said first gas to said torch, and said second pressure regulator valve and said second micrometer valve are the only flow control metering devices used to control a flow rate of said second gas to said torch, and are the only flow control metering devices used to control a ratio of said first gas to said second gas at said brazing torch.

2. The brazing system of claim 1 , wherein the brazing torch has no flow control metering valves.

3. The brazing system of claim 1 , wherein said system further comprises:

a user interface having a first display region, a second display region, a third display region and a fourth display region, where

the first display region allows for user input related to a first gas and allows a user to input a first pressure and any one of a first micrometer valve setting and a first flow rate for said first gas;

the second display region allows for user input related to a second gas and allows said user to input a second gas type and a second pressure and any one of a second micrometer valve setting and a second flow rate for said second gas;

the third region displays a gas ratio between said first and second gases based on said user input in each of said first and second regions; and

the fourth region displays a flame type, a flame energy value and a relative temperature of a flame to be created by said first and second gases; and

a control system coupled to said user input,

wherein said control system uses said user input from said first region to determine the other of said first micrometer valve setting and said first flow rate in said first region, and said control system uses said user input from said second region to determine the other of said second micrometer valve setting and said second flow rate in said second region;

wherein said control system uses said user input from said first and second regions to determine said gas ratio and displays said gas ratio in said third region; and

wherein said control system uses at least two of said user input from said first region, said user input from said second region, said gas ratio and said second gas type to determine each of said flame type, said flame energy value and said flame relative temperature and displays each of said flame type, said flame energy value and said flame relative temperature in said fourth region.

4. The brazing system of claim 1 , wherein said first compartment has at least one opening to allow any of said first gas in said first compartment to escape said enclosure and said second compartment has at least one opening to allow any of said second gas in said second compartment to escape said enclosure.

5. The brazing system of claim 1 , wherein said single enclosure includes a locking mechanism which locks said enclosure and prevents a user from changing settings on any of said first and second pressure regulator valves and said first and second micrometer valves.

6. The brazing system of claim 3 , wherein at least some of said first and second pressure regulator valves and said first and second micrometer valves are controlled by said control system.
