The fiber laser is a core equipment on the fiber laser cutting machine. If the fiber laser fails and shuts down due to improper operation in our daily use, the loss to us is great. In order to reduce the occurrence of such mistakes, we Need more attention when operating. 


In order to reduce the failure rate of the fiber laser, the operator should pay attention to the following matters when using it.


1.Precautions for use during shutdown operation


If there is no cutting task or the rest time exceeds 1 hour during the startup process, it is recommended that the customer turn off the high voltage of the fiber laser, leave the power switch of the fiber laser, and turn off the chiller. When the product needs to be cut again, turn on the chiller and wait for the actual temperature of the chiller's high and low temperature water to reach the set temperature range of less than 1 degree, then apply high pressure to the fiber laser, and then cut out.


Note: It cannot happen that the power switch of the fiber laser is turned off, but the chiller is still running! 


2.Quick boot operation skills (for reference)


When shutting down at night, it is recommended that customers do not turn off the power switch of the fiber laser, so that the air conditioner or internal dehumidifier of the fiber laser is always working and consumes less power. There is no need to wait 30 minutes when the fiber laser is turned on the next day. 


3.Environmental requirements for placing fiber lasers on the customer site


A. It is recommended that the customer purchase a temperature and humidity meter and place it in the fiber laser air-conditioned room to monitor the temperature and humidity in the air-conditioned room.


B.The customer understands the environmental requirements of the fiber laser according to the following environmental temperature and environmental relative humidity table. The low temperature water of the laser is set to 22 degrees, and the ambient temperature of the laser (air-conditioned room temperature) is below 26 degrees, then the relative humidity of the laser environment (air-conditioned room) Relative humidity) should be kept below 75%. If the relative humidity of the laser environment (air-conditioned room relative humidity) exceeds 75%, such as 85%, then the laser ambient temperature (air-conditioned room temperature) must be adjusted below 24 degrees, otherwise the laser will be a risk of condensation. 


If the value of the laser ambient temperature (air-conditioned room temperature) and the laser ambient relative humidity (air-conditioned room relative humidity) are crossed together, if the corresponding value is lower than 22, there will be no condensation inside the laser. If it is higher than 22, there will be condensation inside the laser. Customers can reduce the laser ambient temperature (air-conditioned room temperature) and the relative humidity of the laser environment (air-conditioned room relative humidity) to improve.


Or set the cooling and dehumidification functions of the air conditioner to keep the ambient temperature of the laser no more than 26 degrees, while keeping the relative humidity of the environment less than 60%. It is recommended that customers pay attention to recording the value of the temperature and humidity meter in each shift, so as to find problems in time and prevent risks.


4. Fiber laser requirements for cooling water


It is required to replace the fiber laser cooling water once every three months. The cooling water adopts Watsons distilled water. The conductivity requirement is: 30us/cm<conductivity<50us/cm. If the conductivity is greater than 50us/cm, the cooling water needs to be replaced in time: if the conductivity is less than 30us/cm, pure water can be added to the cooling water. When adding pure water, pay attention to monitoring the conductivity value to avoid the conductivity exceeding the requirement. 


5.Ensure that the chassis is airtight

 

The case of the fiber laser adopts a closed design. Please pay attention to keep the case closed during use to prevent high-temperature and high-humidity outside air from entering the case. 


The following aspects should be paid attention to when checking the airtightness of the chassis:

 

A. Whether the cabinet doors are closed tightly; whether the top lifting bolts are tightened; whether the protective cover of the unused communication control interface at the rear of the chassis is covered, whether the used ones are fixed: whether the power cord inlet is sealed, etc.

 

B. If you need to open the cabinet door of the case due to some reasons during use, you need to turn off the chiller before opening the cabinet door.

 

After you can close the cabinet door, please follow the power-on sequence of the fiber laser, first turn on the power switch of the laser and run it for more than 60 minutes, then turn on the chiller, wait until the actual temperature of the high and low temperature water of the chiller reaches the set temperature ± IC range, and then the fiber laser will be applied.
