Repair & Maintenance
Warning: Should not open up case freely, the max volt inside machine
will be 600V. Must take safe precautions to prevent from being electric
shocked while in maintenance.
1. Apparently misunderstand failures
Normal phenomenon occurs in welding
(1) Welder doesn’t work while in pretty low input volt.
(2) When welder has worked for a long time in high temperature or
in high welding current context , the thermal-sensitive circuit breaker
will tripped to stop welder working, protection lamp will light on
and LED will show “804” protection code. Welder will automatically
reinstate after merely running up for several minutes in open load
(not necessarily shut down welder).
(3) When welder has worked for a long time in high temperature or
in high welding current context, the circuit breaker on the rear panel
will tripped to power off. When this situation occurs, please switch
off the disconnected switchboard. Then halt the welder lasting at
least five minutes to restart. When restarting the welder, please reset
the circuit breaker firstly, then turn on the disconnect switchboard or
switch box to power on welder, finally use for welding after running
up for several minutes in open load.

Attention
1. The input volt range must be between 340-420V, and no phase
missing.
2. Check if the ground leads are connected correctly and firmly.
3. Must wires welding cable to terminal plug socket firmly, otherwise
will burn out the terminal which lead to welding process
instability.
4. Power off as soon as finished welding
5. When use in outdoor, make sure welder be shielded from rains or
snows, but don’t block air circulation.
