4. Operating Instructions
The SIHAO Fiber Laser Marking Machine utilizes a high-speed digital scanning oscillator system for efficient and precise marking.
- Power On: Insert the key and turn it to the ON position. Press the white power button to turn on the machine.
- Software Operation: Launch the laser marking software (e.g., EzCad2.10UNI) on your connected computer.
- Design Your Mark: Create or import your design. The machine is compatible with various software files including PLT, PCX, DXF, BMP, and supports SHX, TTF fonts. It also supports automatic coding, printing serial numbers, batch numbers, dates, bar codes, and two-dimensional codes, as well as automatic jump numbers.
- Place Material: Place the material to be marked on the work platform.
- Focus Adjustment: Use the red light pointer to locate the focal point on your material. Adjust the laser head height with the lifting wheel until the two red dots converge into a single, sharp point.
- Start Marking: Initiate the marking process through the software. The machine will engrave the design onto your material.
- Power Off: After use, press the red emergency stop button, then turn the key to the OFF position and unplug the power cord.

5. Maintenance
The Raycus brand laser source is designed for long service life and is largely maintenance-free for approximately 100,000 hours. However, general care is recommended:
- Keep the machine clean and free from dust and debris.
- Regularly inspect the laser aperture and lenses for any obstructions or damage. Clean gently with appropriate optical cleaning supplies if necessary.
- Ensure proper airflow around the machine, especially for the built-in air-cooled cooling system, to prevent overheating.
- Check all cable connections periodically to ensure they are secure.
6. Troubleshooting
If you encounter issues with your laser marking machine, consider the following general troubleshooting steps:
- No Power: Check the power cable connection, ensure the key is turned to the ON position, and the power button is pressed. Verify the power outlet is functional.
- Laser Not Firing: Ensure the emergency stop button is not engaged. Check software settings to confirm the laser is enabled and the job is initiated correctly. Verify the focal distance is set properly.
- Poor Marking Quality: Adjust the focal distance. Check the material surface for cleanliness. Experiment with laser power and frequency settings in the software, especially for different materials.
- Software Connection Issues: Ensure the USB cable is securely connected to both the machine and the computer. Restart the software and/or the computer.
For persistent issues, please contact customer support.
