2. Safety Information

This laser welder is a Class 2 laser product. Adherence to safety guidelines is crucial to prevent injury and damage to the equipment. Always read and understand all safety warnings before operation.

• Eye Protection: Always wear appropriate laser safety goggles that block 1064nm wavelength during operation. Never look directly into the laser beam or its reflection.
• Electrical Safety: Ensure the machine is connected to a proper 220V/380V power supply. If using 110V, a voltage transformer is required. Do not operate with damaged cables or plugs.
• Ventilation: Ensure adequate ventilation in the work area to dissipate fumes and heat generated during welding.
• Flammable Materials: Keep flammable materials away from the welding area.
• Emergency Stop: Familiarize yourself with the location and operation of the emergency stop button.
• Authorized Personnel: Only trained and authorized personnel should operate this equipment.

5. Setup

Follow these steps to set up your laser welder:

1. Unpacking: Carefully unpack the machine from its shipping crate. Retain all packaging materials for future transport or storage.
2. Placement: Place the machine on a stable, level surface in a well-ventilated area, away from direct sunlight and excessive dust. Ensure sufficient space around the machine for operation and maintenance.
3. Power Connection: Connect the machine to a compatible 220V/380V power outlet. If your power supply is 110V, use a suitable voltage transformer (not included).
4. Water Cooling System: The machine features a built-in water cooling system. Ensure the water tank is filled with distilled or deionized water to the appropriate level before first use and regularly check the water level.
5. CCD and Microscope Setup: Adjust the microscope and CCD observation system for comfortable viewing. Ensure the CCD image is clear on the display screen.
6. Gas Connection (Optional): If using an inert gas (e.g., Argon) for welding, connect the gas supply to the designated inlet on the machine and adjust the flow rate as needed to prevent oxidation.
