Diagnosis of common faults of Robot welding station

According to the frequently-used malfunctions and Robot welding station requirements, we classify common faults so that we can quickly troubleshoot them.

(1) Abnormal fault diagnosis and confirm the setting of the content of the exception, please check the following content first:

Welding method: Confirm whether the selected welding method conforms to the diameter of the wire used and the protection of the gas.

Welding parameters: Confirm that there are no welding anomalies due to changing parameters. Record change parameter, return default value, confirm welding condition.

Welding voltage instruction Method Unified/Individual: Verify that the unified/individual settings of the welding power supply and the unified/individual settings of the manipulator are consistent. The unified/individual settings of the welding power supply are set by unified/individual keys. Moreover, Robot welding station only the manipulator welder characteristic file is correctly set, the welding power supply panel can display the manipulator instruction value correctly.

Select the motor: Confirm the setting value of the F04, the choice of the motor type is correct (0: Micro motor, 2: Mechanical servo motor). If the type of motor is wrong, the wire can not be sent according to the speed of instruction, can not be normal welding.

Select User files: Select User files from the Control Panel, or manipulator selection, you can use F13 settings (F13 off: Control Panel selection, on: Manipulator selection).

Conditional memory: In the selection of welding methods, Robot welding station change the welding parameters, the power of the welding machine before the condition memory. Also, note that if you change the welding method before you adjust the user's file and conditional memory, the changed u parameter disappears.

Encoder WIRES: Encoder wires broken or a, B-phase inverse, wire feed speed will be abnormally accelerated. Also, the wire feed speed display is 0, the fault number Err501 (wire feed wire exception) Please confirm the encoder disconnection connection.

Welding protection gas: Please confirm if the suitable welding gas is selected.

(2) List of abnormal items on the following items, welding power will find the abnormal, automatically stop. When an exception occurs, the buzzer rings and the exception is displayed on the Control Panel. When the anomaly is detected, the arc is cut off signal to the manipulator. However, Robot welding station only when the alarm, welding power will not stop working, nor to the manipulator output arc cut signal.
