First, two main precautions for optical fiber laser marking machine
Prevent fiber breakage
The laser head of the pump system and the laser system is connected by optical fiber.
Users shall ensure that the bending diameter of optical fiber is greater than 300mm during use or transportation.
Severe bending can lead to fiber breakage and laser system failure.
Prevent dust pollution
When the power supply and the optical fiber access port of the laser head are not connected to the optical fiber,
The protective cover provided with the system must be installed to prevent external dust from contaminating the internal optical components.
When the optical fiber cannot be connected to the power supply and laser head,
When the protective cover attached to the system must be installed, prevent the end face of the optical fiber from being polluted.
In serious cases, please use a dust-free paper dipped in alcohol and ether to wipe. Failure to install the protective cover will contaminate the internal optical components and optical fiber end faces,
This will cause the entire laser system to malfunction and void the warranty.
Precautions for laser marking machine?
secondly. About avoiding condensation
Prevent condensation on the surface of laser crystal and LD cavity
The laser system must not be operated in high humidity environments.
The customer shall ensure that the ambient humidity is less than 60%.
When the temperature difference between the laser crystal temperature and the ambient temperature is too large (greater than 10 degrees), condensation may occur on the laser crystal.
The power supply of the controller system is reduced or damaged.
Therefore, when the ambient temperature is much higher than the set temperature of the water tank (more than 10 ℃),
It is strictly forbidden to use the laser system when the water cooler is turned on and the laser head is not working.
Follow these steps to operate the marking machine:
When turning on the machine, first turn on the cooler, wait until the refrigerator temperature is lower than 30 ° C, start the power supply, and then slowly adjust the current to about 10A;
When the temperature of the refrigerator is displayed at the operating temperature (about 18 ° C), slowly turn the current
