a) Starting procedures
Please make sure the control system is on before you turn on the fiber laser. Only after at
least 1 minute since the power turned on, the subsequent operations can be preceded.
b) Frequency set introductions
For model P70QA, the frequency setting range is from 60 kHz to 100 kHz.
c) Laser marking checking
For the device initial testing, first turn the power down to zero without turning on the
marking system after the device is successfully started. Then draw a quadrate, marking
continuously while slowly increasing the power from zero to 100% at the same time.
Meanwhile, use a ceramic material to observe the laser and the laser should become stronger,
otherwise shut down the device and check. If operating normally, the marking system can be
used in common order afterwards.
4.3 Cautions
a) Marking frequency must be in the range of 60~100 kHz for P70QA.
b) It should not modulate the frequency while marking.
c) Stop marking first before shutting down the device, then turn the power down to zero and cut
the power off.
