protection, contact the after-sales department of the
company.
E31
Undervoltage
protection
Input network
voltage is too
low
Turn it off and on again. If this the alarm cannot be
eliminated and the grid voltage remains too low,
check the power grid voltage and wait for the grid to
be normal before welding. If the grid voltage is
normal and the alarm persists, contact professional
maintenance personnel.

Overvoltage
protection
Input network
voltage is too
high
Turn it off and on again. If the alarm cannot be
