Summer is hot, humid and unbearably hot,
Even machines and equipment will be affected,
In high temperature and humidity environment (inside the laser)
Condensation may occur,
Affecting the normal use of the laser.
Dew condensation is a normal natural phenomenon,
But for the influence of equipment,
It is something we need to consider when using the equipment,
Especially in summer, the humidity in the south is higher,
Water drops often appear on the wall,
It has brought a lot of trouble to our life and production.
How to solve the condensation phenomenon of laser cutting machine?
What should we pay attention to?
Ensure the enclosure is sealed
The cabinet of the fiber laser adopts a closed design,
And a chassis air conditioner or dehumidifier is installed,
The purpose is to ensure the safety of all components in the chassis
It is in a relatively stable and safe temperature and humidity environment.
If the chassis is not in a closed state,
High temperature and humidity air outside the chassis
Can enter the inside of the chassis,
When encountering an element cooled by water inside,
It condenses cold on its surface,
Causing possible damage.
Therefore, check the tightness of the chassis
Attention should be paid to the following aspects:
A. Check whether each cabinet door exists and is closed tightly.
B. Whether the lifting bolts on the top are tightened.
C. Unused communication control interface at the rear of the chassis
Whether the protective cover of the,
Whether the used ones are fixed.
Boot Sequence 
Since the laser cabinet cannot be completely sealed,
When the power is cut off at night,
The chassis air conditioner stops operating,
If there is no air conditioner installed in the room or the air conditioner does not work at night,
The hot and humid air outside can gradually penetrate into the chassis.
So when the machine is restarted in the morning,
Note the following operation steps:
A. Start the main power supply of the laser (no light output),
Let the chassis air conditioner run for about 30 minutes.
B. Start the matching chiller,
Wait for the water temperature to be adjusted to a predetermined temperature,
Laser light emission is enabled.
C. Suggestions for normal processing:
If possible, on the premise of ensuring safety,
The laser is not powered off at night,
Keep the chassis air conditioner running.
Or the laser is installed in an air-conditioned room,
And keep the air conditioner running continuously and stably (including at night)
Avoid condensation in the internal and external environment of the laser with its own air conditioner
If the condensation does not form flowing water droplets, nothing will happen,
If there are a large number of flowing water droplets,
And there is water break around the exciter,
Must be a laser with air conditioning
Establish a non dewy working environment.
Avoid condensation in the processing head
It is recommended to add an evaporator between the air source and the machining head,
Keep the gas temperature close to the ambient temperature,
Reduce the risk of condensation.
Water temperature setting
The influence of cooling water temperature on electro-optical conversion efficiency,
It has a direct impact on stability and condensation.
In general,
The cooling water temperature is set as follows:
Water temperature of tap water (cooling laser module)
It should be set at about 21 degrees Celsius.
For a laser of 2500 w or more,
Water temperature of deionized DI water (cooling optical parts)
It should be set between 27 degrees and 33 degrees,
This temperature should be based on the ambient temperature
Adjust the humidity accordingly,
Generally speaking, the higher the ambient temperature, the higher the humidity,
The temperature of DI water should be increased accordingly.
The basic principle is that the DI water temperature should be above the dew point.
