Top 10 common problems and solutions of laser


Top 10 common problems and solutions of laser:

1、 Fault Name: forward light PD alarm

Protection measures: stop the main power supply and turn off the laser.
Possible cause: the PD inside the laser does not detect the laser.
terms of settlement:
(1). restart the laser, do not turn on the laser, and check whether there is red light. If there is no red light, please contact Chuangxin customer service personnel;
(2). if there is red light, please check whether the relevant module can turn on the laser. Check whether the voltage output of DC switch power supply of module power supply is normal.

 

2、 Fault Name: Super return light alarm

Protection measures: stop the main power supply and turn off the laser.
Possible cause: the laser beam combining module detects that the return light is too strong.
terms of settlement:
(1). Check the focus position of the laser;
(2). Check whether the materials are placed horizontally;
(3). Check whether the material is ultra-high reflection material;
(4). Check whether the material thickness exceeds the standard, and give an alarm if it cannot be cut through;
(5). Turn off the laser, suspend use for 3-5 minutes, restart the laser and turn on the laser.

 

3、 Fault Name: pump source temperature alarm

Protection measures: stop the main power supply and turn off the laser.
Possible causes: the pump source temperature of the laser module is too high, and the temperature alarm.
terms of settlement:
Turn off the laser, and check whether the flow rate and water temperature of the water cooler are normal, and whether the water pipe is blocked.
After the inspection, restart the laser and the laser returns to normal. If not, contact Chuangxin customer service staff.

 

 

4、 Fault Name: QBH installation alarm

Protection measures: stop the main power supply and turn off the laser.
Possible cause: poor contact between QBH output contact and cutting contact.
Solution: turn off the laser, check the laser QBH output head and cutting head, and re install.

 

5、 Fault Name: emergency stop alarm

Protection measures: stop the main power supply and turn off the laser.
Possible cause: the emergency stop switch is pressed.
Solution: the emergency stop switch returns to normal state, restart the laser.

 

6、 Fault Name: water flow alarm

Protection measures: stop the main power supply and turn off the laser.
Possible cause: the water cooler is abnormal, resulting in the decrease of water flow.
Solution: turn off the laser, check whether the flow rate and water temperature of the water cooler are normal, and whether the water pipe is blocked.
After the inspection, restart the laser and the laser returns to normal.

 

7、 Fault Name: abnormal communication alarm

Protection measures: stop the main power supply and turn off the laser.
Possible cause: there is no signal transmission between single module communication line and main module.
terms of settlement:
1. Check whether the signal line between single module and main module is loose;
2. Check whether the single module can power on and start normally, whether there is red light, and whether the auxiliary power supply voltage output works normally.

 

8、 Fault Name: maximum current alarm

Protection measures: stop the main power supply and turn off the laser.
Possible cause: the working current of single module pump exceeds the maximum limit.
terms of settlement:
(1).Restart the laser after it is turned off and check whether it is normal; If normal, normal use;
(2). If the maximum current alarm is still given, the driving MOS tube in a single module may break down, so the laser should be turned off immediately and the customer service personnel of Chuangxin should be contacted.

 

9、 Fault Name: water cooling plate alarm of electric module

Protection measures: stop the main power supply and turn off the laser.
Possible causes: the temperature of the water cooling plate of the laser module is too high, the temperature alarm.
terms of settlement:
Turn off the laser, and check whether the flow rate and water temperature of the water cooler are normal, and whether the water pipe is blocked. After the inspection, restart the laser and the laser returns to normal. If not, contact Chuangxin customer service staff.

 

10、 Fault Name: water cooling plate temperature alarm of beam combiner

Protection measures: stop the main power supply and turn off the laser;
Possible causes: the temperature of the water cooling plate of the laser beam combiner is too high, and the temperature alarm is given.
terms of settlement:
Turn off the laser, and check whether the flow rate and water temperature of the water cooler are normal, and whether the water pipe is blocked. After the inspection, restart the laser and the laser returns to normal. If not, contact Chuangxin customer service staff.
