1. Safety Instructions

WARNING: Failure to follow these safety instructions may result in serious injury, equipment damage, or fire. Laser radiation is extremely hazardous to eyes and skin.

• Laser Safety:

  • NEVER look directly into the laser beam or its reflections.

  • ALWAYS wear the provided laser safety goggles (OD 7+ for the appropriate wavelength) before operating the machine.

  • Ensure all personnel in the work area are aware of the laser hazard and are wearing appropriate protective eyewear.

  • Place warning signs around the work area.

• Electrical Safety:

  • Ensure the power supply matches the machine's voltage requirements (e.g., AC 220V±10%, 50/60Hz).

  • Connect the machine to a properly grounded electrical outlet.

  • Turn the main power switch to "OFF" before making any electrical connections.

  • Use the provided power cable; do not use damaged cables.

• Fire Safety:

  • Keep the work area clean and free of flammable materials (e.g., paper, solvents, cloth).

  • Always have a fire extinguisher readily available.

  • Do not leave the machine unattended while it is powered on.

• General Safety:

  • Do not disassemble any part of the machine while it is powered on.

  • Ensure the cooling system is functioning properly before operation.

  • Only trained and authorized personnel should assemble and operate this equipment.

3. Assembly & Connection Procedure

Follow these steps in sequence for correct assembly.

Step 1: Positioning the Main Units

1. Place the Laser Power Supply Unit and the Water Chiller on a stable, level surface near a grounded power outlet.

2. Ensure there is at least 30cm of clearance around the units for proper ventilation.

Step 2: Connect the Cooling System

1. Locate the water inlet and outlet ports on the Laser Power Supply Unit and the Water Chiller. They are typically labeled "IN" and "OUT."

2. Connect one water hose from the Chiller's OUTLET to the Power Supply's INLET.

3. Connect the second water hose from the Power Supply's OUTLET to the Chiller's INLET.

4. Tighten all hose connections securely to prevent leaks.

5. Fill the Water Chiller reservoir with the provided purified water or coolant to the indicated level. Do not use tap water.

Step 3: Connect the Handheld Welding Gun

1. Identify the multi-pin connector on the end of the Welding Gun cable.

2. Align this connector with the corresponding socket on the front panel of the Laser Power Supply Unit.

3. Push the connector in firmly and secure it by tightening the threaded collar (if applicable). Ensure this connection is tight and secure.

Step 4: Connect the Control Foot Pedal

1. Plug the foot pedal connector into the dedicated "FOOT PEDAL" port on the Power Supply Unit.

2. Place the foot pedal in a comfortable and accessible position on the floor.

Step 5: Connect the Power

1. Ensure the main power switch on the Laser Power Supply Unit is in the "OFF" (O) position.

2. Plug the power cable into the Power Supply Unit's socket and then into the grounded wall outlet.

3. Connect the Water Chiller to a separate power outlet.

4. Initial Startup and Check

1. Power On the Chiller: Turn on the Water Chiller. You should hear the pump start and see the water temperature and flow rate on its display. Confirm that the cooling system is operating normally.

2. Power On the Main Unit: Turn the main power switch on the Laser Power Supply Unit to the "ON" (I) position.

3. System Initialization: The machine will perform a self-check. Wait for the system to fully boot up. The control screen should display the main menu.

4. Check for Leaks: Visually inspect all water hose connections for any signs of leakage. If a leak is found, POWER OFF IMMEDIATELY and tighten the connection.

5. Gas Connection (if applicable): Connect your shielding gas (e.g., Argon or Nitrogen) cylinder to the "GAS IN" port on the Power Supply Unit. Set the gas regulator to the recommended pressure/flow rate (refer to welding parameters guide).

5. Software & Parameter Setup

1. On the touchscreen, navigate to the parameter setting menu.

2. Set the initial welding parameters (Power, Frequency, Duty Cycle, Wire Feed Speed) based on the material and thickness you will be welding. Consult the Welding Parameter Chart provided in the full User Manual.

3. Perform a test run on a sample piece of the same material to fine-tune the parameters.

Troubleshooting (Basic)

Note: This guide covers basic assembly and initial setup. For detailed operation, advanced parameter settings, maintenance schedules, and full troubleshooting, please refer to the complete User Manual provided with your machine.
