**Introduction:**
This laser welder is specifically designed for jewelry welding by HaiNuoxin, primarily used in the perforation and spot welding of gold and silver jewelry. Laser spot welding is a key part of laser technology applications. The process involves thermal conduction, where laser radiation heats the surface of the workpiece, and the heat spreads into the interior through conduction to melt the material. By controlling the pulse width, energy, peak power, and frequency, a specific molten pool is formed. Due to its unique advantages, it is widely applied in the production of gold and silver jewelry as well as in the welding of small and delicate parts.
**Features:**
1. A wide range of adjustable parameters including energy, pulse width, frequency, and spot size allows for various welding effects.
2. Parameters are adjusted using a lever within the sealed cavity, making operation simple and efficient.
3. The ceramic converging cavity is imported from the UK, offering high resistance to corrosion and high temperatures, with an expected lifespan of 8–10 years. The xenon lamp has a life of over 8 million cycles.
4. Equipped with an advanced light shielding system that protects the eyes during operation. It can run continuously for 24 hours, ensuring stable performance and requiring no maintenance for up to 10,000 hours.
5. Ergonomically designed to reduce fatigue during long working sessions.
**Advantages:**
High-speed, high-efficiency, deep penetration, minimal deformation, small heat-affected area, excellent welding quality, clean and environmentally friendly weld spots.
