The argon in the argon storage tank is delivered into the inflation tank 14 through the hose, buffered in the inflation tank 14 and then enters the inflation groove 13 through the air holes 17. The slot of the inflation groove 13 sprays argon outward to form an inert protection zone, so as to improve the thermal efficiency and the weld quality. The plurality of air holes 17 are arranged at equal intervals along the length direction of the inflation groove 13, so that the gas in the inflation tank 14 uniformly enters the inflation groove 13.
