protection
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.
