ZS100 Fiber Laser Jewelry Spot Welding Machine

High-Power Desktop Laser Welder for Professional Jewelry Manufacturing & Repair

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.


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.


Energy-Saving & Environmentally Friendly Design

  • 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.


Wide Range of Jewelry Applications

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
