装置。[Claims for Utility Model Registration] 1. In a water-cooled plasma arc processing device that processes a workpiece while cooling water by passing it through the torch, a gas provided in the middle of a cooling water supply pipe to the torch. A branch pipe for introduction, a DC solenoid valve that opens and closes the introduction of gas into the branch pipe, a power supply device that supplies processing power to the torch and the workpiece, and a power supply device that supplies power to the power supply device. and a voltage-responsive switch that closes when power supply to the power supply device is stopped, and at least the capacitor is provided with a series circuit of the voltage-responsive switch and the excitation coil of the DC solenoid valve. A water-cooled plasma arc processing device comprising a time-limited operation circuit of the DC solenoid valves connected in parallel. 2 The gas supply side of the DC solenoid valve has a pressure switch that closes due to the presence of gas pressure, and the time-limited operation circuit of the DC solenoid valve connects the capacitor to the voltage responsive switch and the excitation coil of the DC solenoid valve. 2. The water-cooled plasma arc processing apparatus according to claim 1, wherein the water-cooled plasma arc processing apparatus is constructed by a circuit in which a series circuit consisting of contacts of the pressure switch and the pressure switch are connected in parallel.
