Communication control system compatible with welding device based on analog interface

The invention discloses a communication control system compatible with a welding device based on an analog interface. The communication control system comprises a power source system used for providing a power source, a control signal receiving circuit, a work control circuit, a signal collecting circuit and a signal feedback circuit. The control signal receiving circuit is used for receiving and converting control signals, sent to the welding device, of a mechanical arm/an automatic tool. The work control circuit is used for being matched with the welding device and controlling the welding device to work. The signal collecting circuit is used for collecting and directly feeding back the welding device output current and voltage to the mechanical arm/the automatic tool. The signal feedback circuit is used for feeding back the collected welding device output current and voltage to the mechanical arm/the automatic tool after conducting abnormality judgment on the collected welding device output current and volt
