Error Management
Low battery (clock) :
The message « Low battery (clock) » appears after switch ON of the machine and alerts
the user that the voltage of the battery on the command board is too low. This battery
ensures the saving of the date and time when switching OFF the machine.
Tool out of order :
The message « Tool out of order » appears after switch ON of the machine and alerts the
user that a button or trigger is constantly pressed, or a permanent short-circuit is
detected. Control the trigger of the gun, as well as the buttons on the clamps in order to
make this message disappear.
Current too low
Insufficient air pressure
Before the welding spot: If the input air pressure is too low to reach the required electrode force, the machine will beep
and display the following error message “Insufficient Pressure”.
Pressing the button allows the user to force the execution of the welding spot, which will be performed with the air
pressure available. If the actual measured clamping force is too low, then the machine will display the following message
“Low Pressure”.
Different events might cause the appearance of error messages. They can be classified
in three categories
:
-
General Warnings: i.e overheating, lack of electrode force or welding current, etc…
These messages appear on the screen, and remain until a key is pressed.
-
Installation Errors (air pressure, electrical power supply).
-
Major Faults: These defects cause the display of an error message that locks the
machine
-
The thermal protection relies on a thermostat located on the diode bridge, this feature
will lock the machine, and display the message “overheating”
If the welding current measured during the spot is 6% less than the setting, the machine
will display the error message “Current too low” - the welding spot should be checked.
A message will be displayed at the end of every welding spot, showing the measured
welding current. This message is displayed on the screen until a key on the control panel is
pressed, or until a new welding spot is performed, by pressing the B button on the clamp.
If the machine cannot deliver the requested current, then the following message appears.
The welding spot is not performed, and the message must be acknowledged to perform a
welding spot
.
