1. Laser energy is not good, pulse width, current, duty cycle can be processed.

2. If the defocusing amount of the focusing mirror is not correct, the defocusing amount should be adjusted to be close to the focus position.

1. If the cooling speed of the workpiece is too fast, the temperature of the cooling water on the fixture should be adjusted to improve the water temperature.

2. If the gap between the workpiece is too large or there are burrs, the machining accuracy of the workpiece should be controlled.

3. The workpiece is not cleaned, so it is necessary to clean the workpiece from the beginning.

4. If the flow rate of protective gas is not correct, the flow rate of protective gas can be readjusted to deal with it.

1. The protective gas is not turned on, just turn on the protective gas to deal with it.

2. The air flow direction of the protective gas is wrong, so that the air flow direction of the protective gas is opposite to the movement direction of the workpiece.
3. The protective gas selected is not correct, so try to replace the protective gas.
4. If the protective gas flow is not enough, increase the flow rate or replace the gas cylinder.

In winter, if the temperature of the water cooler is too low, it may cause the pipeline of the water cooler to freeze. Because the density of the ice is less than the density of the water, it will lead to the fracture or deformation of the cooling water pipe due to the volume expansion of the water cooler and the equipment to be cooled, which will cause serious damage to the relevant core components. Therefore, radium laser specially reminds you to take precautions.
