Too low temperature in winter will cause some damage to the laser equipment. If it is not used properly, it may lead to serious damage to the internal core components of the laser equipment and can not be recovered! So, today we look again at the C02 laser cutting machine in winter how to anti-freeze treatment.

All kinds of gas

Laser tube

Carbon dioxide laser tubes are cooled by water, and it's best to keep the temperature around 25 degrees, because that's where the energy is strongest.

Antifreeze measures for CO2 laser cutting machine in winter

In fact, the laser tube is very important in winter anti-freezing and summer anti-high temperature. In winter, when the laser tube is not working, if the water in the tube is not put clean, the cooling layer of the laser tube will freeze and expand, and the laser cooling layer will swell and crack, leading to the normal work of the laser tube. In winter, the freezing crack of the cooling layer of the laser tube is not within the scope of the warranty. In order to avoid unnecessary losses, please do it in the correct way.

First, use an air pump or air compressor and other auxiliary equipment to drain the water in the laser tube. Customers who use water chiller or water pump can remove the water chiller or water pump and place it in a room with high temperature to prevent water circulation equipment from freezing and cause damage of parts such as water chiller and water pump, which will bring unnecessary trouble to you.

It is also important to note that do not add excessive antifreeze in the laser tube, because the cooling layer of the tube will affect the quality of the light. For the laser tube, the higher the frequency, the more frequent the water change frequency. Otherwise, calcium, magnesium and other impurities in the pure water will be attached to the inner wall of the laser tube, affecting the energy of the laser. Therefore, frequently change the water, when not to put the water clean is the most important.

Cold water machine

Chiller is also one of the key anti-freezing laser equipment. In the cold winter, many users will think that the cold weather water temperature will not increase much. So often forget to change the water, especially in winter, because the outside temperature is very low, the spindle motor heating is difficult to feel out.

In addition, antifreeze can be used. It is generally composed of alcohols and water, requiring high boiling point and flash point, specific heat and conductivity, low temperature viscosity is small, not easy to bubble, not corrosive metal parts, rubber hoses, etc.. It is added to the water tank of the chiller supporting the laser equipment to prevent the cooling water from freezing, so that the chiller can start up and operate normally in the cold winter.
