B、There are 6 indicators on Operation panel, demo THC from Torch
down—Touch workpiece—arc start---arc feedback---Auto on, please check
the failure reason from the one by one step.
2.2 voltage divider
Our Voltage Divider offers two 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
Divided Arc Voltage guided into THC is Time-Delayed.
It just needs to prolong the time of lead Arc Voltage into THC, this interference can be
avoid effectively.
