Because the wall of the large anode main body used for large current and ultrahigh temperature is relatively thick, the temperature of the large anode main body is difficult to be reduced to a proper range only by cooling from the outer wall of the spiral. When the temperature of the large anode is in a high state for a long time, the working life of the large anode is short; and because the cooling effect to big positive pole is limited, lead to being close to the gas of big positive pole main part center through-hole inner wall to be difficult to receive better cooling, can't form the better cold airflow of effect for the hot compression effect of electric arc is relatively poor. Accordingly, the present embodiment provides a high current plasma generator anode electrode to solve the above-identified problems. The specific scheme is as follows:
