QCW Portable Handheld Laser Spot Welding Machine
🔬 Quasi-Continuous Wave Precision Technology
QCW pulsed laser technology delivers microsecond-level precision with high peak power and low heat input. Ideal for ultra-fine spot welding on heat-sensitive components where traditional continuous wave lasers cause thermal damage.
⚡ Key Features
High-definition stereoscopic microscope provides magnified view of the welding zone. Enables precise positioning for sub-millimeter spot welds on jewelry, electronic components, and micro-molds.
Quasi-continuous wave technology achieves peak power up to 3000W in microsecond pulses. Deep penetration with minimal heat-affected zone - perfect for dissimilar metal welding and thin foil materials.
Adjustable spot diameter from 0.2mm to 2.0mm with precise energy control. Single-pulse, multi-pulse, and continuous pulse modes for unmatched welding flexibility.
Lightweight at only 45-65 kg with integrated air cooling. Easy to transport between workstations or to customer sites for on-location jewelry and mold repair services.
