1: After the laser cutting machine is not working, do not turn off the water cooler.

After the laser cutting machine is not working, please ensure that the power supply will not be cut off (power failure), and do not turn off the water cooler.

The coolant is always in a circulating state, so the normal temperature can be adjust to about 10°C.

In this way, the coolant temperature cannot reach the freezing point, so the laser cutting machine will not be damaged.

2: Discharge the coolant in the laser cutting machine

Drain the coolant in all parts of the equipment through the drain of the laser cutting machine.

And inject pure gas to ensure that there is no coolant in the entire water circulation cooling system.

This also ensures that the laser cutting machine will not be damaged due to low temperatures.

3: Replace the coolant in the laser cutting machine

Cars driving on roads in winter will replace the antifreeze use in winter, and vehicles can also be add to the equipment.

But please make sure to choose a big brand of antifreeze, otherwise the antifreeze will contain impurities, if it adheres to the pipeline of the laser and other components, it will cause damage to the equipment.
