1. The carving depth is not enough

The carving is not deep at the beginning of the work, please follow the following order to troubleshoot the problem

(1) Check whether the supporting point of the laser tube is reasonable;

(2) Whether the light intensity (current) is set too low;

(3) Whether the optical path is offset;

(4) Whether the focal length is correct;

(5) Whether there are scratches and dirt on the surface of ytterbium sheet;

(6) Whether the flow and pressure of cooling water are normal.

The problem of insufficient carving and cutting depth occurs after the machine works for a while

(1) Check whether the supporting point of the laser tube is reasonable;

(2) The water temperature is normal;

(3) Whether the lens is hot during operation;

(4) Whether the flow and pressure of cooling water are normal;

(5) Whether the cooling water is clean.

2. High voltage ignition and discharge

(1) Check whether there is dirt or moisture around the high voltage head of the laser;

(2) Whether it is too close to the metal part of the machine;

(3) Whether the high-voltage connection device of the laser power supply falls off from the support;

(4) Whether the high-voltage connection device is broken or damaged inside;

(5) Low water temperature causes condensation water (sweating) on the pipe wall and water jacket.

3. The laser tube is broken

(1) The water in the laser is frozen due to low water temperature;

(2) The laser is not supplied with water;

(3) Water pressure is too low;

(4) Whether the water flow direction complies with the principle of "low in, high out", and the water is not enough to fill the laser, causing local heating of the water cooling pipe.

4. Causes of high-voltage discharge and breakdown

(1) The power supply does not match or the power supply of different specifications is used to work (use a high-power power supply to excite low-power tubes). The laser tube is damaged due to exceeding the rated voltage that the laser tube can withstand.

(2) The water cooling condition is not good, and the cooling water is not full of the whole water cooling pipe, and there are bubbles. In the position without water cooling, the local temperature is too high, which leads to the change of glass properties and local damage of the laser tube glass.

(3) The influence of temperature, raw materials, process and other factors during the production of glass materials causes tiny bubbles or uneven thickness in the glass materials, which may cause damage to the weak position under high-voltage discharge.

5. Instructions for using laser power failure detection

The following inspection methods should be carried out under the condition that the laser tube is free from appearance damage.

(1) If the laser power supply has the detection function, when the laser is in the standby state of the power supply, press the test switch, the laser light will be on, and the laser tube will output the laser. If the light is not on, the laser power supply is broken; If the light is on, the laser tube will not emit the laser, and the laser will be damaged.

(2) If the laser power supply has no detection function, the signal ports 5V and IN of the laser power supply are connected with wires; 50. The three ports P and G are connected. After the laser power supply is powered on, the current is above 10mA. At this time, the laser has no laser energy output or the laser energy output is relatively weak, indicating that the laser is bad; If the current is below 10mA, the laser power supply is broken.

Note: If the above problems do not exist, please contact our company for after-sales consultation and handling.
