the Note of Glass CO2 laser tube which is using
1. Connected to the cooling water, using the principle of low prices, adjusting the outlet location to ensure that the cooling water filled with cooling tube, the tube can not be there the bubble, then turn the power on. Requirements: cooling water to soft water (distilled or purified water), and to always pay attention to the water temperature of cooling water, the water temperature should be controlled at 25 ¡æ -30 ¡æ range, not too high or too low, especially in summer, once the water temperature is too high, The cooling water should be replaced or shut down to rest for some time: cold regions cooling water shall not be frozen, especially the laser after the shutdown, no cooling water retention in the laser tube, so that cooling water ice lead to the burst. (Special Note: AC users, the cooling water tank must be grounded);
Laser tube two points of support in the laser tube length of 1/4 point, to ensure that the cooling water flow in the 2L-4L / min; otherwise ineffective, cause the jump mode, spot change a few points lead to power decline; cooling water outlet in the tank must be covered by water, or the power of each off the laser tube cooling pour dissatisfaction phenomenon.
2. Attention to the protection of the laser output window to avoid the course of their work (including the process of debugging the optical path), the smoke produced by sputtering to the surface of the output window, to prevent the output window surface is contaminated, the power will drop, when available in cotton or silk dipped in anhydrous alcohol to gently wipe the outer surface of the output window;
In the debugging process by adjusting the laser support points or rotating laser position to achieve the best output effect, and then fixed laser
Be sure to note: to avoid the high voltage electrode near to the accumulation of dust, to keep dry, high-pressure side as much as possible farther away from the metal to prevent high-voltage spark discharge.
Laser in the course of six, can not have the scale formed in the cooling pipe within the cooling water to avoid clogging the cooling effect of variation. Once found, can be used 20% diluted hydrochloric acid cleaning cooling pipe to remove scale.
7 laser glass, fragile. Install and use, to avoid the local force.
Rationalization laser tube, to save laser energy, the best point of the laser tube operating current is 16 mA.
