FAQ
1. What is QCW laser welding?

QCW (Quasi-Continuous Wave) combines high peak pulse power with low average heat, allowing deep penetration on thin materials without burning through.

2. What materials can it weld?

Stainless steel, carbon steel, aluminum, copper, and other metals.

3. Why is it air-cooled?

Air cooling makes the unit portable (60kg) and maintenance-free. No chiller or water changes needed.

4. Can it weld thin sheets?

Yes. The 0.2mm spot size and pulse control make it perfect for thin materials (0.3-2mm) with minimal deformation.

5. What is the difference between 150W and 300W?

150W for fine welding (jewelry, thin parts). 300W for deeper penetration and thicker materials.

6. Is it easy for a beginner?

Yes. Handheld design with simple controls. Beginners can learn within one day.

7. What is the warranty?

1 year. Online technical support available.

    We print labels for small paper cups. This mini printer fits on our workbench. The automatic feeder works smoothly, almost no jamming.

    The automatic mode is worry-free. Printed a full mural without any ink break. Quieter than I expected.
