PRODUCT DETAILS
High Laser Power
200W/300W YAG laser ensures reliable, high-energy welding performance for gold, silver, platinum, and more. It enables clean, precise joins even on delicate or intricate jewelry designs without damaging adjacent areas.
High Single-Pulse Energy
Delivers up to 150J single-pulse energy for deeper penetration and stronger welds. Ideal for both micro-welding and larger structural connections in complex jewelry components or repairs.
Ultra-Fine Adjustable Width
Supports 0.4–3mm welding width to handle everything from ultra-fine filigree work to wider seams. Flexibility meets a range of jewelry production and repair requirements easily.
Clear CCD Monitoring
Equipped with a 720P CCD and 8-inch screen with crosshair. Provides sharp, real-time visibility for precise targeting, boosting operator confidence and reducing error rates during welding.
Stable Energy Output
With energy instability below 2%, it guarantees consistent weld quality. This minimizes spatter, porosity, and defects, ensuring superior finish on valuable jewelry pieces.

Adjustable Pulse Settings
Pulse width 0.1-15ms and frequency 1-50Hz provide full control. Fine-tune to suit different metals, thicknesses, and joint requirements for perfect results every time.
Long Continuous Operation
Supports up to 24 hours of continuous work without overheating. Perfect for high-volume workshops or production lines requiring reliable, long-duration operation.
Compact, Low-Noise Design
Compact size (1100×680×1370mm) and ≤60dB noise level fit small workshops or retail spaces. Provides a quiet, clean working environment without compromising power.
Easy Maintenance System
Uses replaceable protective glass/lens and features easy access to consumables. Lowers operating costs while maximizing uptime and machine longevity.
Flexible Power Compatibility
Works with AC220V±10% at 50/60Hz. This ensures stable performance across different regions and workshop setups, with 6KW power demand for efficiency.
