The summer heat has gripped the entire country. Many places have daytime heat indexes exceeding temperatures of 400 degrees or more. As the summer heat and rainfall in the north and south are different, especially in high temperature or high humidity environment, we must pay attention to prevent the laser and cutting head condensation. At the same time to remind the laser operator to pay attention to appropriate rest and more hydration reasonable summer heat.
Laser and cutting head for the laser cutting machine is an important optical component, summer condensation problems light alarm can not be cut properly need to wait for the humidity to drop to lift the alarm. Heavy or burned electrical components or optical components causing significant losses. In order to analyse the principle of condensation more intuitively we need to check the dew point table.
When the laser cooling water temperature is set below the corresponding dew point temperature in the table, condensation will occur. For example, through the temperature and humidity to find the current room temperature of 40 degrees, air humidity is 50%, when the laser cooling water temperature is set at 27.6 degrees and below, the risk of condensation is certain to exist. At this time we should set the laser air conditioning room air conditioning temperature of about 20-25 degrees. (Ideal ambient temperature for laser operation is 10-25 degrees with humidity below 50 per cent.)

The cutting head cooling water belongs to the external cycle water, and the laser cooling water is separated from the separate circuit, the cutting head cooling water and the laser QBH interface cooling water belongs to the series relationship. The cooling water temperature requirement of the external optical circuit is more lenient, and the water temperature can be appropriately adjusted in summer to avoid condensation, but it should not be higher than 30 degrees.

When the cutting head is suspected of condensation, you can view the astigmatism value of the cutting process. When the cutting quality is significantly reduced and the astigmatism value is greater than 500 should immediately stop cutting, and check the water circulation temperature of the external optical circuit of the chiller. And contact the laser after-sales service engineers to assist in testing or repair!
Hot summer, higher temperatures chiller water tank in the cooling water deterioration will be accelerated, here to remind the majority of customers must bear in mind the use of regular distilled water and regular water changes, maintenance, as well as cleaning or replacement of the chiller inlet filter, radiator dust, etc.. The chiller will be placed in a ventilated place, prohibited in the chiller above the air vent or around the pile of debris.
Lastly, remind: laser, chiller switch on and run half an hour before starting the cutting task, this time the water temperature and humidity has reached the set range.
