The invention relates to the technical field of welding robots, in particular to a device for automatically adjusting welding protective gas flow. One end of an encoder fixing support is connected with an encoder fixing plate, and the other end of the encoder fixing support is connected with a double-shaft stepping motor. One end of the single-film coupler I is connected with a short shaft at one end of the double-shaft stepping motor, and the other end is connected with an output shaft of the encoder; one end of the single-film coupler II is connected with a long shaft at the other end of the double-shaft stepping motor, and the other end is connected with an air valve shaft of the air valve; the air valve is connected with the double-shaft stepping motor through an air valve fixing plate. According to the automatic welding gas flow adjusting device, gas flow is automatically adjusted through forward and reverse rotation and different rotating speeds of a double-shaft stepping motor, a closed-loop detection
