The light control of the laser die cutting machine is mainly affected by the laser tube, the laser power supply, the water circulation system and the light-emitting signal for the laser die cutting machine. The light-emitting signal includes the light-emitting signal given by the control board, the water protection signal for the laser die cutting machine., the door switch signal and the like. Therefore, the light is not mainly from the laser tube laser power water circulation system and the light signal for  the laser die cutting machine.

Generally, first check whether the laser power supply is normally energized, whether the outer tube of the laser tube is abnorma for the laser die cutting machine., and whether the water circulation system is normal. If it is not normal, replace it or adjust it accordingly for the laser die cutting machine.In the normal situation of the above aspects, the optical signal problem should be considered. Generally, the short-circuit signal (short-circuit laser power supply current 5v and ain short-circuit water protection p and gnd with lock-free switch control l and gnd) is used first. for the laser die cutting machine.
