Skills for adjusting the power of laser marking machine

Principle of adjusting laser power
The power of the laser marking machine directly determines the depth and speed of marking. Different materials have different requirements for laser power, and adjusting the laser power to be just right can ensure the best marking effect.

Choose the appropriate power size
1. Metal materials:
For metal materials, high-power lasers are required for marking, usually between 10W-100W. Insufficient power can result in poor marking results or inability to meet requirements.
2. Non metallic materials:
For non-metallic materials such as plastic, glass, rubber, etc., appropriate power should be selected for operation according to the color, hardness, and thickness of different materials. Generally speaking, the power range is between 2W-50W.
3. Wood and paper:
For fiber materials such as wood and paper, lower power laser marking has better results, generally between 5W-15W. Excessive power can cause excessive melting of the material surface, affecting the quality of marking.

How to adjust laser power
1. Adjust the current:
Adjusting the current is the most important method for adjusting laser power, which requires operating the power supply equipment for adjustment. Different devices have different power modules, please refer to the device manual for specific operation.
2. Adjust the working distance:
Adjusting the distance between the laser head and the target object can affect the focusing degree of the laser, thereby adjusting the power level. Generally speaking, the closer the distance between the laser head and the work platform, the greater the power; The farther the distance, the lower the power.
3. Adjust the tungsten pen:
The pressure of the tungsten pen in the laser marking machine will affect the size of the laser power. When marking non-metallic materials, adjusting the pressure of the tungsten pen can regulate the laser power. It needs to be adjusted according to the requirements of different materials and pen tips.

Tips and Precautions
1. Avoid excessive frequency of repeated marking.
2. The surface of the material needs to be dried and cleaned before processing to ensure high-quality marking.
3. Different colors of materials need to be adjusted for different powers to avoid local light or light gray when marking.
4. It is necessary to regularly check the operation status of the equipment and replace vulnerable components such as power modules and lasers in a timely manner.

In short, adjusting the power of the laser marking machine is a crucial step in the marking process. Reasonable power adjustment can ensure the improvement of marking quality and production efficiency.
