• Nozzle: Directs the laser beam and shielding gas.
• Protective Glass: Shields internal optics from spatter and debris.
• Focusing Lens: Concentrates the laser beam to a precise spot.
• Reflector: Redirects the laser beam within the head.
• Motor: Component for internal mechanisms, potentially beam oscillation or wire feeding.
• Collimator: Ensures the laser beam is parallel before focusing.
• Wire Feeding Bracket: Supports the wire feeder mechanism (if used with a compatible system).
• Switch Button: Activates the laser.
• Waterways: Channels for the cooling system.
• QBH Protective Sleeve: Connects the laser head to the fiber optic cable from the laser source.

4. Setup and Installation

Proper setup is crucial for optimal performance and safety. The SUP23T is designed for ease of installation and maintenance.

1. Connect to Laser Source: Securely attach the QBH protective sleeve to your compatible laser source's fiber optic output. Ensure all connections are tight and free from damage.
2. Cooling System: Connect the waterways to your external cooling system. Verify proper coolant flow before operation.
3. Gas Supply: Connect the appropriate gas lines for shielding gas (if required for your application).
4. Power Connection: Ensure the laser source and any associated control systems are correctly powered according to their respective manuals.
5. Lens Installation: The focusing and protective lenses feature a pull-out design for easy installation and replacement. Ensure they are clean and correctly seated.
6. Collimating Lens: The collimating lenses are integrated with the QBH for easy on-site replacement.
7. Motor Maintenance Window: Utilize the motor maintenance window for easy alignment and inspection of internal components.

5. Operating Instructions

The SUP23T offers four primary functions: welding, cleaning, cutting, and gap cleaning. Select the appropriate function and parameters on your laser source control system.

1. Power On: Activate the laser source and control system according to their respective manuals.
2. Parameter Setting: Adjust laser power, pulse duration, frequency, and other relevant parameters on your laser source for the desired application (welding, cleaning, cutting, or gap cleaning).
3. Focus Adjustment: Adjust the vertical focal length (±10mm) and spot adjustment range (Line 0-8mm) as needed for your application.
4. Initiate Operation: Hold the SUP23T firmly using its ergonomic design. Press the switch button to activate the laser.
5. Perform Task: Guide the laser head smoothly and consistently over the workpiece. Observe the process carefully and adjust parameters as necessary.
6. Power Off: Release the switch button to deactivate the laser. Follow the shutdown procedure for your laser source and cooling system.
