Since November, the winter in China has begun, the temperature is getting lower and lower, and many northern areas have experienced a heavy snowfall. When the temperature drops and the weather turns cold, in order to ensure the normal operation of the fiber laser cutting machine in winter, it is necessary to take corresponding anti-freezing measures.
 
1. In winter, the weather is cold and the temperature is low. The pipes of the chiller may freeze due to the low ambient temperature, which may cause damage to the core components of the fiber laser cutting machine. For this problem, the following protection work should be done.
The recommended method for preventing icing is to keep the water chiller and the equipment at a temperature above 0 °C.
If the temperature does not reach above 0 °C, keep the cooled equipment and the water chiller turn on. If the water in the pipe is always flowing, it can prevent icing. Of course, in this case, if the water chiller is shut down for a long time due to a malfunction or a power outage, there is also a certain risk of icing.
If the above methods are not possible, for the water chiller, you can add the antifreeze. You don’t need to add too much refrigerant, just 25%. After adding antifreeze, it can resist -20 °C without freezing.
 
2. Due to the different climates in the northern and southern hemispheres, some areas are humid and rainy in winter, and the air environment is humid. Excessive humidity inside the fiber laser cutting machine will cause condensation of the internal components of the laser. Therefore, it is necessary to reduce the humidity of the environment around the laser. After the main power of the laser is turned on and before the laser emits light, turn on the attached control cabinet The air conditioner runs for 30 minutes to prevent the components in the cabinet from malfunctioning due to moisture.
 
3.  If the fiber laser cutting machine is not used for a long time in winter, the water in the water tank will deteriorate due to long-term non-replacement, or freeze due to low temperature, which will damage the metal laser cutting machine parts. In order to ensure the normal operation of the laser sheet metal cutting machine, all the water in the water tank should be drained before stopping use, one end of the small water pipe should be removed, and all the water should be blown out with air.  When turning it on again, first check whether the machine is freezing and whether the room temperature is above 0 degrees.
 
Everyone can use fiber laser cutting machine in cold winter. As long as anti-freezing measures are taken, the fiber laser cutter can operate normally.
