ZS100
The ZS100 Fiber Laser Jewelry Spot Welding Machine is a high-performance desktop laser welder designed for professional jewelry production and precision repair.
Equipped with a 100W fiber laser source, the ZS100 delivers higher pulse energy, deeper penetration, and superior welding stability compared with lower-power models, making it ideal for both fine and demanding jewelry welding tasks.
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.
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.
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.
Total machine power consumption: 500W
No consumables such as xenon lamps or crystal rods
No chemicals, fumes, or wastewater
Quiet and clean operation
The ZS100 significantly reduces long-term operating costs while meeting modern environmental requirements.
The ZS100 is widely used for:
Gold, silver, and platinum jewelry welding
Ring resizing and reinforcement
Necklace, chain, pendant, and bracelet welding
Claw and prong repair
Micro-welding of fine jewelry components
Custom jewelry making and professional repair
Compatible materials:
Gold
Silver
Platinum
Stainless steel
Titanium and other fine metals
Laser type: Fiber laser generator
Laser power: ≥100W
Max pulse energy: 10J
Pulse width: 0.5–50 ms
Frequency: Up to 50 Hz
Energy stability: ≤1.5%
Spot size: 0.3–1.5 mm
Cooling method: Forced air cooling
Power supply: 110V–240V, 50/60Hz
Machine size (L×W×H): 550 × 300 × 430 mm
Net weight: 25 kg
Working temperature: 10–45°C
Relative humidity: 20%–85%
| Item | ZS100 Fiber Laser | YAG Laser |
|---|---|---|
| Cooling | Air-cooled | Water-cooled |
| Maintenance | Maintenance-free | Regular maintenance |
| Energy efficiency | ~30% | ~3% |
| Consumables | None | Xenon lamp, crystal rod |
| Service life | Up to 100,000 hours | Shorter, frequent replacements |
| Operating cost | Low | High |
