Input network
voltage is too
low
Please turn it off and reboot. If this phenomenon
persists and the grid voltage continues to be too
low, please check the power grid voltage and wait
for the grid to be normal before welding. If the grid
voltage is normal and there is still under voltage
alarm, please contact professional maintenance
personnel.
(The standard version does not have the function)
Input network
voltage is too
high
Please turn it off and restart. If this phenomenon
persists and the grid voltage continues to be too
high, please check the power grid voltage and wait
for the grid voltage to return to normal before
welding. If the grid voltage is normal and there is
still under voltage alarm, please contact
professional maintenance personnel. .
Please turn it off and restart it. If this phenomenon
persists, please contact professional maintenance
