Exceeding the maximum allowed power from the current source – check that the welding program
parameters do not exceed the characteristics of the current source (including Free mode)
Over voltage of the 3 phase power supply of the power source of (tolerance 400V - 3 ~ 15 %/-20 %) -
Verify the characteristics of the power supply
Under voltage of the 3 phase power supply of the power source of (tolerance 400V - 3 ~ 15 %/-20 %) -
Verify the characteristics of the power supply
Overtaking of the maximum average current authorized by the power source - verify that the parameters of
the program of welding do not exceed the characteristics of the power source (Free mode in particular)
Overtaking of the maximum instant current authorized by the power source - verify that the parameters of
the program of welding do not exceed the characteristics of the power source (Free mode in particular)
Overtaking of the duty cycle of the power source – wait for the cooling of the power source
Automatic mode only
Time out of 3 seconds after the welding launch without detecting striking
Automatic mode only
Detection of arc break
Call of a non authorised or non existing program
The program is not compatible with this software version. Please upgrade the software version of the
power source.
The configuration is not compatible with this software version. Please upgrade the software version of the
power source.
A program is corrupted. This program is visible in the programs management page of the power source. A
removal of the program is required.
The installation configuration is corrupted. Please configure again the installation.
A program list is corrupted. Please configure again the program lists.
A peripheral has been reset. Please restart the power source.
The power supply is unstable. Please check the electrical wiring.
Impossible to achieve the automatic calibration
Check that the procedure of calibration displayed on the screen is well respected
Immediate request from user to stop the welding
No communication with a peripheral.
Check the peripheral connection.
It is imperative to connect and disconnect the wire feeder when the installation is out of power.
Flow problem of the cooling unit
MMA only
Detection of the sticking of the electrode with the workpiece. Unstick the electrode
MIG only
Detection of the sticking of the wire with the workpiece. Cut the wire
Excessive torque of the wire feeder motor.
Check that the wire sheathing is clean and that nothing is blocking the motor advance or the wire feeding
movement
Check that the tightness of the rollers is not too important
Launching of a welding program where user synergy is not present in the generator – import or define the
user synergy corresponding to the current program
Overtaking of the low threshold of welding current monitoring defined by the user
Overtaking of the high threshold of welding current monitoring defined by the user
Overtaking of the low threshold of welding voltage monitoring defined by the user
Overtaking of the high threshold of welding voltage monitoring defined by the user
Overtaking of the low threshold of wire feeder motor current monitoring defined by the user
Overtaking of the high threshold of wire feeder motor current monitoring defined by the user
Software is missing for a dedicated peripheral. Please perform again a software upgrade.
The communication with a peripheral is highly disturbed. Please check the peripheral connection.
It is imperative to connect and disconnect the wire feeder when the installation is out of power
