3. The intelligent control panel will boot up. Use the wireless mouse and keyboard to navigate the interface.

5.2 Basic Welding Process

1. Select Welding Mode: On the intelligent control panel, choose the appropriate welding mode (spot, butt, overlap, sealing) and material settings (copper, aluminum, etc.).
2. Adjust Parameters: Set welding parameters such as output power (1500W/2000W/3000W), welding speed (0-20000mm/s), and pulse settings via the control panel.
3. Position Workpiece: Place the battery or material to be welded on the machine's workbench.
4. Adjust Cantilever Arm: Utilize the three-axis linkage to precisely position the welding head over the target area. Adjust the welding height using the height limit device for optimal focus and weld quality.
5. Wear Protective Gear: Always wear laser protective glasses before initiating welding.
6. Initiate Welding: Use the handheld welding key switch to control the laser. Press down the welding head firmly onto the workpiece to begin the welding process.

5.3 Material Compatibility and Thickness

The LA-15H02 supports welding various materials with adjustable precision:

• Aluminum Sheet: Thickness 1-2.5mm
• Copper Sheet: Thickness 0.3-1.5mm
• Copper Aluminum Composite Sheet: Thickness 1-2.5mm

5.4 Marking Function

The intelligent operating system includes a marking function. Navigate to the marking interface on the control panel to create or import graphics, patterns, or text for laser marking on battery ear electrodes or battery outer box nameplates. Adjust marking parameters as needed.

6. Maintenance

6.1 Water Chiller Maintenance

The LA-15H02 is equipped with a dual temperature dual control constant temperature water tank. Regularly check the coolant level and quality. Replace the coolant according to the manufacturer's recommendations to ensure optimal cooling performance and prevent overheating of the laser source.

6.2 General Cleaning

• Keep the machine and work area clean and free of dust and debris.
• Wipe down the exterior of the machine with a soft, dry cloth.
• Periodically clean the protective lenses to ensure clear vision and optimal laser performance.

7. Troubleshooting

This section provides general guidance for common issues. For complex problems, please contact technical support.

• No Power: Check power cable connections, main power switch, and circuit breaker.
• Laser Not Firing: Ensure safety interlocks are engaged, protective covers are closed, and the welding key switch is properly activated. Verify parameters on the control panel.
• Poor Weld Quality: Adjust welding parameters (power, speed, pulse), ensure proper focus, clean protective lenses, and verify material thickness compatibility. Check for proper contact with the workpiece.
• Chiller Alarm: Check coolant level, ensure proper water flow, and verify working environment temperature is within the recommended range (15-35°C).
