b) Make sure signal line of laser and marking system are properly connected.
4.2 Operation procedures
a) Starting procedures
Please make sure the controlsystem 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 P20QS, the frequency setting range is from 30KHz to 60KHz.
For model P30QS, the frequency setting range is from 40KHz to 60KHz.
c) Laser marking checking
For the device initial testing, firstturn the power down to zero without turning on the
marking system after the device is successfully started. Then draw a quadrate, marking
continuously whileslowly 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 of30~60 KHz for P20QS, 40~60 KHz for
P30QS.
b) It should not modulate the frequency while marking.
Stop marking first before shutting down the device, then turn the power down to zero
and cut the power of.
