9. Troubleshooting
Warning! Before arc welding machines are dispatched from the factory, they
have already been checked thoroughly. The machine should not be tampered
with or altered. Maintenance must be carried out carefully. If any wire
becomes loose or is misplaced, it maybe potentially dangerous to user! Only
professional maintenance personnel should repair the machine!
Ensure the power is disconnected before working on the machine. Always
wait 5 minutes after power switch off before removing the panels.

Elimination of general problems in MMA
Symptom Reasons Troubleshooting
After startup, the fan
does not turn or the wire
feeding speed is
abnormal The air temperature
may be too low or
the fan may be
damaged
If the temperature is too low, leave the
machine to work for a while. The
temperature in standby will rise the fan
and resume normal operation. If it is still
not working, it is necessary to replace
the fan.
