PROBLEM TO BE SOLVED: To properly control the output by discriminating an electric characteristic of a pouring liquid. SOLUTION: A designated detection current is caused to flow from an output transformer circuit 105 by electric power not causing dielectric breakdown in an insulating liquid 161 or in the atmosphere under the control of a control circuit 101, in the lapse of designated time for stabilizing the output, the current values detected by current sensors 106a, 106b are A/D converted and measured by a sensor signal processing circuit 107, and it is determined whether a treatment electrode and a return electrode are in a conductive liquid or an insulating liquid or in the atmosphere to conduct the output control processing. |
