CO2 laser is composed of carbon dioxide, nitrogen, hydrogen and other gases and produces a laser wavelength of 10.6μm. It is often used for laser marking and laser cutting. Because it is composed of gas pipes, many problems should be paid attention to when using it to avoid adverse consequences.
1. When using, please connect the cooling water first, adopt the principle of low inlet and high outlet, adjust the position of the outlet pipe to ensure that the cooling water is full of the cooling pipe and there can be no bubbles in the pipe, then turn on the power. Requirements: Use soft water (distilled water or purified water) as the cooling water, and always pay attention to the temperature of the cooling water. The water temperature should be controlled within the range of 25℃-30℃, and not too high or too low, especially in summer. Once the water temperature is found to be too high, The cooling water should be replaced in time or shut down for a period of rest: the cooling water in cold areas must not be frozen, especially after the laser is shut down, the cooling water must not be stored in the laser tube to prevent the cooling water from freezing and causing explosion. (Special attention: users who use AC power, the cooling water tank must be grounded);
