Precautions for the use and maintenance of laser engraving machine in winter

Winter is the most prone to failure stage for the laser engraving machine, because the temperature is low and it is easy to freeze, which is a fatal blow to the laser tube. The CO2 laser tube is made of glass, and it is easy to freeze and crack the laser tube at low temperature. How to maintain for new users?

The CO2 laser tube of the laser engraving machine is cooled by water circulation, and the temperature is generally 25°C. In high latitude areas, the weather is cold in winter. In order to prevent the laser tube from being frozen and cracked, users should take anti-freezing measures. For the maintenance of the laser tube of the laser engraving machine, there are the following three suggestions:

(1) Pay attention to the indoor temperature, which should not be lower than 0℃, especially the night temperature, and keep the indoor temperature not lower than the icing critical value.

(2) Empty the liquid in the laser tube after the daily work is completed to prevent freezing. Also pay attention to check the circulating water status before starting up.

(3) Pay attention to keeping the circulating water clean. The circulating water of the laser tube needs to use pure pure water or mineral water. However, due to various reasons, many customers choose tap water as the circulating water. If tap water is used, the water needs to be changed frequently to ensure that the water is clean.

Specific measures to prevent freezing of laser engraving machine in winter

1. After using the laser machine, first disconnect the main power supply, turn off the water pump or chiller, disconnect the silicone tube at the water inlet and outlet of the laser tube, and drain the water inside. The laser tube with power> 60W can also be blown clean with an air pump or a small air compressor.

2. If the laser tube is cooled by a water pump, pay special attention. There is a thick black tube in the water circulation of the water pump, which is water protection. Also make sure that the water inside is clean, otherwise it will freeze and crack the water for protection.

You can also remove the laser tube and pour out the water. In this case, the position of the laser tube may change slightly. Re-dimming is required when reinstalling.

3. There is a sewage outlet and a rotating head under the chiller. The water can be released after screwing it down, which is very convenient. After the water is drained, the chiller can be placed in a place where the temperature is relatively high. Use it next time and add pure water again.

If you find it troublesome, you can add antifreeze. According to local temperature changes, the ratio of antifreeze to water is not the same. You can come to or consult an antifreeze vendor based on the actual situation.

4. The laser marking machine or high-power machine (500W) cannot add antifreeze, because the working principle of the laser inside is different. There will be more steps. Turn off the machine, turn off the cold water, and find a tube with a diameter of 8 mm. Unplug the inlet and outlet pipes and drain the water inside. If there is any residue, the inside may be cracked and damaged.

Customers who use 500W laser engraving machine must ensure that the room temperature is stable.
