Leave the unit running so that the
overheated components cool as
rapidly as possible.
When the problem is solved, the
welding power source will reset
automatically.
All functions disabled.
Exceptions:
• cooling fan.
• cooler (if switched on).
• Make sure that the power re -
quired by the welding process is
lower than the maximum rated
power output.
• Check that the operating condi-
tions are in compliance with the
welding power source data plate
specifications.
• Check for the presence of ad -
equate air circulation around the
welding power source.
WARNING
NO COMMU-
NICATION
Indicates the presence of prob -
lems in data communication be-
tween the power source and wire
feeder.
When the problem is solved, the
welding power source will reset
automatically.
Exit the alarm state by performing
one of the following actions:
• Switch the power source off.
All functions disabled.
Exceptions:
• cooling fan.
• cooler (if switched on).
• Check that the connecting cable

feeder is intact and make sure
the connectors are securely
tightened.
• Check the data transmission
wiring inside the power source
and the wire feeder.
• Check for correct operation of
the control board in the power
source and the Motor Board in
the wire feeder.
