Touching any current-carrying parts may cause a fatal electric shock or
burn injury
To prevent a fatal accident, such as an electric shock, burn injury, etc.,
make sure to observe the following:
●To secure physical safety, only educated and/or skilled persons who well understand the machine should
perform Troubleshooting work.
●Make sure to turn off the power switch, the switch of the distribution box and related devices (external devices

· Please turn on power switch after solving the problem causing emergency stop
signal.
E03
Over temperature
The internal temperature is too high.
• Do not turn the power off until the internal temperature is reduced. (After the
internal parts cools down, abnormal alarm disappears and machine resume to
normal).
• Remove the causes of internal temperature increase. (Excessive duty cycle or
foreign substances near the side ventilator and/or the rear air inlet.)
E04
Over input voltage
The input voltage has exceeded the permissible limit. The input voltage allowed
limits are as follows:
• Turn off the power of this product
• Set the input voltage to ±20% of rated ones
• Turn on the power again.
E05
Low input voltage
The input voltage is lower than the permissible limit. The input voltage allowed
limits are as follows:
• Turn off the power of this product
• Set the input voltage to ±20% of rated ones
• Turn on the power again.
E06
Arc start failure
The current can’t be detected within certain time after pressing cutting torch
switch.
•After turning off the power, confirm base metal (wire cut or poor connection
etc.) And try to remove the cause of the problem.
The number of arc ignition in air exceeds the upper limit.
E07
The cutting torch
switch abnormity
When the cutting torch switch is pressed, turn on power switch.
