Detailed Operation Methods of Mini Handheld Fiber Laser Marking Machine

Preparation Before Operation

1. Safety Check

• Wear protective goggles (specific to the laser wavelength)

• Ensure proper ventilation in the working area

• Check that the emergency stop button is functional

2. Equipment Setup

• Fully charge the battery or connect to power source

• Install the handheld marking head securely

• Connect to computer/controller if required for design transfer

3. Material Preparation

• Clean the surface to be marked (remove oil, dust, etc.)

• Position the material on a stable, flat surface

• For curved surfaces, use appropriate fixtures

Basic Operation Steps

1. Power On

• Turn on the main power switch

• Wait for system initialization (typically 10-30 seconds)

2. Parameter Setting

• Power (usually 20-80% of maximum)

• Frequency (20-100 kHz for most materials)

• Marking speed (100-2000 mm/s)

• Filling density (0.01-0.2 mm)

• Select material type in the software (metal, plastic, etc.)

• Adjust parameters:

3. Focus Adjustment

• Measure or estimate working distance (varies by model)

• Adjust the focus lens to the correct distance

• Perform test marks to verify focus quality

4. Design Import/Creation

• Create text, logos, barcodes, etc.

• Import vector files (DXF, AI, PLT formats)

• Adjust size and position

• Use included software to:

5. Positioning

• Use the red positioning laser (if equipped)

• Manually position the marking head at the correct distance

• Verify position with a test pulse (low power)

6. Marking Execution

• Press the trigger button (handheld models)

• Or click "Start" in the software (connected models)

• Maintain steady hand movement for consistent marking

Advanced Functions

1. Variable Depth Marking

• Adjust power in different areas of the design

• Use grayscale processing for depth variation

2. Serial Numbering

• Set up automatic sequence numbering

• Configure increment patterns (date, batch numbers, etc.)

3. Database Connection

• Link to external databases for dynamic marking

• Automatically pull serial numbers or product info

4. Barcode/QR Code Generation

• Generate 1D or 2D codes directly

• Set error correction levels for QR codes

Post-Operation Procedures

1. Shutdown Sequence

• Turn off laser power first

• Then shut down control system

• Finally disconnect power source

2. Maintenance

• Clean lenses with alcohol and lens tissue

• Check and clean ventilation filters

• Inspect cables for wear

3. Troubleshooting Common Issues

• Faint marking: Increase power or slow speed

• Burn marks: Reduce power or increase speed

• Uneven marking: Check focus and material flatness

Safety Precautions

1. Never operate without proper eye protection

2. Avoid marking reflective materials without special settings

3. Keep flammable materials away from marking area

4. Regularly inspect equipment for damage

5. Follow all manufacturer-specific safety guidelines
