- Connect Water Chiller:
- Connect the water inlet and outlet hoses from the laser unit to the corresponding ports on the S&A CWUL-05 Water Chiller.
- Fill the chiller with distilled or deionized water to the recommended level.
- Connect the chiller's power cable to a suitable power outlet.
- Connect Laser Engraver:
- Connect the laser engraver's power cable to the provided transformer, then connect the transformer to a suitable power outlet (110V-240V/50-60Hz).
- Connect the USB cable from the laser engraver to your control computer.
- Install Software: Insert the provided USB drive into your computer and install the laser marking software. Refer to the software user manual on the USB drive for detailed installation instructions.
- Optional Rotary Axis (D80): If using the D80 Rotary Axis, connect it to the designated port on the laser engraver's control unit and secure it to the workbench. Refer to its specific instructions for setup and calibration.

5. Operating Instructions
This section outlines the general operating procedure for the UV laser engraver. Always refer to the detailed software manual for specific software functions.
Figure 5: UV Laser Marking Working Principle
- Power On Sequence:
- Ensure the water chiller is powered on and operating correctly. Check for any alarms.
- Turn the key switch on the laser engraver control box to the 'ON' position.
- Launch the laser marking software on your computer.
- Material Preparation: Place the material to be marked on the workbench. Ensure it is flat and securely positioned. For cylindrical objects, use the D80 Rotary Axis.
- Focus Adjustment: Adjust the height of the laser head to achieve optimal focus on the material surface. The digital user manual provides guidance on focus methods.
- Software Operation:
- Import or create your design within the software. The machine is compatible with files from Coredraw, AutoCAD, Photoshop, and supports formats like PLT, PCX, DXF, BMP.
- Set engraving parameters such as laser power (10%-100% adjustment range), marking speed (up to 8m/s), repetition rate (20-200kHz), and engraving depth (0.01-0.5mm, material dependent).
- Use the 'Red Light Preview' function to verify the marking area and position on your material.
- Start Marking: Once parameters are set and the preview is confirmed, press the 'Start' button in the software or use the foot switch to begin the engraving process.
- Emergency Stop: In case of any malfunction or emergency, immediately press the red emergency stop button on the control box.
- Power Off Sequence: After use, exit the software, turn the key switch to 'OFF', and then power off the water chiller.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your laser engraver.
- Optical Components: Periodically clean the laser lens and galvanometer mirrors with a specialized optical cleaning solution and lint-free wipes. Avoid touching optical surfaces with bare hands.
- Water Chiller:
- Check the water level regularly and refill with distilled or deionized water as needed.
- Clean the chiller's dust filter every 1-3 months, depending on the operating environment.
- Replace the chiller water every 6-12 months to prevent algae growth and maintain cooling efficiency.
- General Cleaning: Keep the machine and workbench clean and free of debris, especially around moving parts and ventilation openings.
- Cable Inspection: Periodically inspect all cables for wear or damage. Replace any damaged cables immediately.
