Interconnected CO2 welding control system

The invention discloses an interconnected CO2 welding control system. The interconnected CO2 welding control system comprises a CO2 gas shield welding unit, a control unit, and an execution unit, wherein the CO2 gas shield welding unit comprises a welding machine, a first operation terminal, an electric current detection sensor, a voltage detection sensor, a logic processor and an information transmitter; the control unit comprises a second operation terminal, an information processor, a memory and an emitter; the execution unit is a smart phone or a receiver carried by an electric welding operator or related personnel; and the smart phone or the receiver is used for receiving information sent by the emitter. The interconnected CO2 welding control system has the advantages that the electric welding operator or related personnel knows the abnormal fluctuations of the welding parameters in real time, and can know the duty cycle and maximum output power of a welding machine in the using process; the problems tha
