The basic principle of anti-freezing of 6090 laser cutter is to keep the coolant in the laser cutting machine from reaching the "freezing point". Let's take a look at several methods.

　　When the 6090 laser cutter does not work to ensure that the power supply will not be cut off (power failure), do not turn off the water cooler. The cooling liquid is always in a circulating flow state, and the normal temperature can be adjusted to about 10 °C. In this way, the coolant temperature will not reach the freezing point, so it will not damage the laser cutting machine.

　　Drain the coolant from the various parts of the machine through the drain of the 6090 laser cutter. And inject pure gas to ensure that there is no coolant in the entire water circulation cooling system. This can also ensure that the laser cutting machine will not be damaged by low temperature.

　　Replacing the coolant in the laser cutting machine

　　Be sure to replace the 6090 laser cutter in time after the winter has passed. Cars running on the road in winter will replace the antifreeze used in winter, and car antifreeze can also be added to the equipment.

　　The above methods play an important role in whether the 6090 laser cutter can work normally in winter and equipment safety. The first two methods are recommended. Method 1 saves time and effort, but if there is a sudden power failure, it may cause damage to the 6090 laser cutter. The second method is laborious and wasteful. But it is indeed safer and more effective than the other two methods.
