    • The present invention obtains an automatic mode switching of DC plasma torches through, which easily switches DC plasma torches to be run between a transmitting mode and a non-transmitting mode and put the switching device under the monitor and the control of a current sensor and a current level controller; the heat generated by the current passing through can be transferred by a non-combustible liquid driven by a pump and be cooled down through a heat exchanger; and, electric arcs is prevented from happening between two electrodes by the non-combustible liquid.
    • 本发明获得了一种直流等离子体炬的自动模式切换,通过这种方式可以切换直流等离子炬在发射模式和非发射模式之间运行,并将开关装置置于监视器之下,并控制电流传感器和 电流控制器; 通过电流产生的热量可以由泵驱动的不燃液体转移并通过热交换器进行冷却; 并且通过不可燃液体防止电弧在两个电极之间发生。
