There are many reasons why the laser output of a marking machine may become weak. Below, we analyze the issue assuming the laser source itself is functioning properly and provide solutions to resolve weak laser output.

1. Misaligned Focus

A misaligned focus can lead to weak laser output. To fix this:

• Adjust the laser marking machine's focus to the correct focal length.
• Adjustment Method:
  • Create any random graphic in the software and ｓｅｌｅｃｔ Continuous Processing.
  • The laser will emit continuously. Adjust the marking machine's column up or down gradually.
  • When the sound of the laser is loudest and the light is brightest, the correct focal length is achieved.

2. Incorrect Laser Parameters

If the laser marking machine's parameters are set too low, the output may weaken.

• Adjust the speed parameter to 500 (do not set it too high).
• Increase the power parameter appropriately.
• These adjustments can resolve weak laser output caused by parameter settings.

Additional Considerations

• The weak laser issue can also result from improper operation, laser source aging, or material incompatibility.
• Test the laser output on various materials to determine if the issue is related to the workpiece material.

By following these steps, you can troubleshoot and resolve weak laser output in your marking machine effectively.
