220V voltage will provide the circuit with +12V working power. When IC begins to oscillate, its 3 pin will output low frequency pulse signal. When IC's 3 pin outputs high level, K is connected, V is illuminated and VL1 goes out.After 220V voltage is rectified, it will generate 1000V high voltage which will be put onto the high voltage electrode. When IC's 3 pin outputs low level, K is released, VL2 goes out, VL1 is illuminated. K's K1 and K2 are connected, and the high voltage generator stops working.
