QCW (Quasi-Continuous Wave) combines high peak pulse power with low average heat, allowing deep penetration on thin materials without burning through.
Stainless steel, carbon steel, aluminum, copper, and other metals.
Air cooling makes the unit portable (60kg) and maintenance-free. No chiller or water changes needed.
Yes. The 0.2mm spot size and pulse control make it perfect for thin materials (0.3-2mm) with minimal deformation.
150W for fine welding (jewelry, thin parts). 300W for deeper penetration and thicker materials.
Yes. Handheld design with simple controls. Beginners can learn within one day.
1 year. Online technical support available.
