Error Indication
When an error occurs, an error code appears on the front panel of the laser welding machine controller.
Errors are categorized into alarm and warning depending on their details.
This chapter describes the details and measures of errors.
Alarm
Errors that occur when highly emergent safety function is activated or there is any abnormality in laser welding machine are
output as alarm.
When an alarm occurs, the laser supply (laser pumping) is turned OFF, and the laser radiation is stopped if during lasing.
