For the Plasma which touch the introduced arc voltage, it is no influence for the high
adjusting machine by using none-Isolation voltage-divided; when using the HF introduced
arc voltage increase the time of taking arc voltage to avoid the process of
introducing arc voltage.
5.2、 Isolation Voltage-Divided
Isolation voltage-divided machine has limited disturbance since it make the Plasma arc
voltage get the none Isolation voltage-divided of 100:1 and connect to high adjusting machine after
processed by Isolation circuit.
