9.2. Alarm and solutions
Continuously
output the
maximum capacity
current of the
welder
Restart the welder. If it is still in overcurrent
protection, contact the after-sales department
of the company.
Input network
voltage is too low
Turn off and restart the machine. If this the
alarm cannot be eliminated and the grid
voltage remains too low, check the power grid
voltage and wait for the grid return to normal
before welding. If the grid voltage is normal
and the alarm persists, contact professional
maintenance personnel.
Input network
voltage is too high
Turn off and restart the machine. If the alarm
cannot be eliminated and the grid voltage
remains too high, check the power grid
voltage and wait for the grid return to normal
before welding. If the grid voltage is normal
and the alarm persists, contact professional
maintenance personnel.
Undervoltage in the
driver
Turn off and restart the machine. If the alarm
cannot be eliminated, contact professional
maintenance personnel.
Inverter IGBT
temperature is too
high
Do not turn off the machine. Wait for a while,
and then continue welding after the indicator
goes out.
Output rectifier
diode temperature
is too high
Do not turn off the machine. Wait for a while,
and then continue welding after the indicator
goes out.
No-load voltage is
too high
Turn off and restart the machine. If the alarm
cannot be eliminated, contact professional
maintenance personnel.
NOTE! After applying the above countermeasures, the alarm still cannot be lifted or
reappears after lifting. Please contact professional maintenance personnel.
