The utility model discloses an automatic brazing flame control system which comprises a fuel gas pipeline, and a ball valve, a manual pressure regulating valve, a first electromagnetic valve, a three-way branch pipeline input point, a mass flow controller, a welding flux generator and a high-pressure one-way valve are sequentially arranged on the pipeline. A ball valve, a manual pressure regulating valve, a three-way branch pipeline output point, a second electromagnetic valve, a two-way gas slip ring and a shunt block are sequentially arranged on the nitrogen pipeline; a ball valve, a manual pressure regulating valve, a third electromagnetic valve, a mass flow controller and a high-pressure one-way valve are sequentially arranged on the oxygen pipeline; the manual pressure regulating valves are respectively connected to a pressure gauge with a display function, and the tail ends of the gas pipeline and the oxygen pipeline are connected to a welding gun. The nitrogen pipeline is communicated with the fuel gas
