High-Efficiency Fiber Laser Technology

The ZS100 uses an advanced fiber laser generator with excellent beam quality and outstanding energy efficiency.

• Laser output power: ≥100W

• Maximum pulse energy: 10J

• Electro-optical conversion efficiency up to 30%

• Power stability ≤ 1.5%, ensuring consistent welding results

• No noticeable power attenuation for 3–5 years of continuous use

This technology provides a major advantage over traditional YAG laser welding machines, especially in long-term reliability and operating cost.

Precision Spot Welding Performance

The ZS100 is engineered for high-precision jewelry welding, even on delicate or intricate designs.

• Adjustable spot size: 0.3 – 1.5 mm

• 3× electric beam expander for accurate and repeatable spot control

• Pulse width adjustable from 0.5 to 50 ms

• Maximum frequency: 50 Hz

• Minimal heat-affected zone, preventing deformation, cracks, or discoloration

The result is clean, strong, and visually flawless welds, even on thin chains and fine prongs.

Maintenance-Free Air Cooling System

Unlike traditional YAG jewelry welders, the ZS100 adopts a forced air-cooling design.

• No water chiller required

• No risk of water leakage

• Lower maintenance and operating costs

• Compact structure ideal for desktop use

This makes the ZS100 especially suitable for jewelry workshops, retail repair counters, and small factories.
