This LED illuminates if an incorrect operating condition occurs.
An alarm message appears on the following display: D2
Tab. 2 - Alarm messages
MESSAGE MEANING EVENT CHECKS
AL. HEA.
Overheating alarm
Indicates tripping of the welding power source thermal
protection.
Leave the unit running so that the overheated
components cool as rapidly as possible.
When the unit has cooled, the welding power source
will reset automatically.
All functions disabled.
Exceptions:
-
Cooling fan.
- Cooler (if switched on).
- Make sure that the power required by the
welding process is lower than the maximum
rated power output.
- Check that the operating conditions are in
compliance with the welding power source
data plate specifications.
- Check for the presence of adequate air
circulation around the welding power source.
Phase missing alarm
Indicates the absence of a phase in the power supply
line.
The message appears when the mains protection
activation LED switches on.
All functions disabled.
Exceptions:
-
Cooling fan.
- Check if the equipment power supply line has
all the phases.
If the problem persists:
-
qualified technical personnel are required for
repair/maintenance jobs.
AL. Coo.
Cooler alarm
Indicates insufficient pressure in the torch liquid
cooling circuit.
All functions disabled.
Exceptions:
- Cooling fan.
The alarm message persists on the
display until the first operation is
performed on the user interface.
Signalling of the alarm depends on
the following settings:
- Coo = on: the alarm is signalled if
the cooling unit is connected to
the power source and if it is
running.
- Coo = oFF: the alarm is never
signalled, irrespective of the
circumstances.
- Coo = Aut: the alarm is signalled
if the cooling unit is connected to
the power source and if it is
running.
- Check that the connection to the cooler is
correct.
- Check that the "O/I" switch is set to "I" and
that it illuminates when the pump is running.
- Check that the cooler is filled with coolant.
- Check that the cooling circuit is liquid tight,
notably the torch hoses and the internal
connections of the cooler.
E. 69
Software compatibility error
Indicates that the welding power source has a
software version that is not compatible with the remote
device connected to it (remote controller, wire feed
unit).
All functions disabled.
Exceptions:
-
Cooling fan.
- Update the remote device software.
E. 04 Alarm, no-load voltage failure
All functions disabled.
Exceptions:
-
Cooling fan.
- Check to ensure the welding torch is not
resting on the workpiece connected to
ground.
- Check that when the power source is
switched on there is no short circuit between
the sockets (voltage must be greater
than/equivalent to U
r
).
If the problem persists:
- qualified technical personnel are required for
repair/maintenance jobs.
CAn Err.
No communication alarm
Indicates the presence of problems in data
communication between the power source and wire
feeder. When the unit has cooled, 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 between
power source and wire feeder is intact and
make sure the connectors are securely
tightened.
If the problem persists:
- qualified technical personnel are required for
repair/maintenance jobs.
