Machine features

  • The heat-affected zone of welding is small, the welding point is firm and beautiful, the heat-affected zone is small, the welding quality is high, the operation is convenient, the speed is fast, the efficiency is high, the depth is large, the deformation is small, and the environment is environmentally friendly and pollution-free.

  • The energy, pulse width, frequency, and spot size can be adjusted within a larger range to achieve a variety of welding effects. The parameters are adjusted by the control lever in the closed cavity, which is simple and efficient.

  • Adopting the ceramic condenser cavity imported from the United Kingdom, corrosion resistance, high temperature resistance, high photoelectric conversion efficiency, the life of the condenser cavity (8-10 years), and the life of the xenon lamp is more than 8 million times.

  • Adopting the world's most advanced automatic shading system, eliminating the irritation of human eyes during working hours, humanized design, ergonomic, long-term work without fatigue.

FAQ & Answers

Supports platinum, 18K gold, and 925 silver, as well as applications in eyeglass hinges, watch micro-components, decorative jewelry parts, and miniature sensor electrodes.

Especially ideal for edge detail repair and ring joint reinforcement, making jewelry maintenance more precise and reliable.

The jewelry spot welder uses a non-contact energy focusing system with an extremely small heat-affected zone, preventing surface discoloration, metal diffusion, or structural deformation.

Safe to use in delicate structures or tight component areas, producing smooth and nearly invisible welds that maintain both aesthetics and strength. In most cases, no further polishing is required for seamless appearance.

Perfect for jewelry workshops, watch and eyeglass repair shops, metal artisans, and micro-electronics repair engineers requiring high precision.

Also suitable for small-batch production and material testing. Widely adopted by R&D units and academic labs as a platform for precious metal micro-welding and material property analysis.

With its compact size, no consumables or flux needed, plus microscopic observation and one-point trigger design, it is easy to operate and highly accurate. Even beginners can quickly get started.
