A: To prevent freezing, the normal operating ambient temperature of the laser must be between 5-40℃. Beyond this range, the operational stability of the laser will be affected, and more serious laser damage could result.

During holidays, if the ambient temperature of the equipment can be maintained above 5℃, the laser does not need special protection, and the equipment can be turned on or off. If the ambient temperature is below 5℃, the water in the laser and water cooler should be discharged to avoid frost damage to the laser, water chiller and reflector path lens caused by low temperature.
