2. THC is on Auto Model;
3. Arc voltage has been lead in THC;
4. Actual Arc Voltage not higher than Set Arc Voltage over 30V.
Note:
A. When THC on Auto Mode, the 5 indicators all should be ON, if anyone is OFF, that
means Auto Mode failed, please check the reason according to indicators.
B. There are 6 indicators on Operation panel, demo THC from Torch down - Touch
workpierce - arc start-arc feedback - Auto on, please check the failure reason from
the one by one step.

Voltage divider
Our Voltage Divider offers tow modes of Voltage Divide; None Isolation Voltage
Divide is backup for Isolation Voltage Divide.
2.2.1 None Isolation Voltage Divide
Note: Plasma Output positive pole is GND, negative pole connected with electrode in
torch. DO NOT mis-connected, or THC will be Un-effective .
As none isolation voltage divide is directly connected with plasma power supply, to
enable THC escape from interference caused by the HF during Plasma Arc Start, the Divide
Arc Voltage guided into THC is Time-Delayed.
It just needs to prolong the time of lead Arc Voltage into THC, the interference can be
avoid effectively.
