Jewelry laser spot welding machine features-Suntop

Features of jewelry laser spot welding machine

1. The whole machine can be placed on the desktop, and the built-in water cooling design occupies a small space.

2. Energy, pulse width, frequency, and spot size can be adjusted in a wide range to achieve various welding effects.

3. The parameters are adjusted through the control rod in the closed cavity, which is simple and efficient.

4. The ceramic concentrating cavity imported from the UK is used, which is corrosion-resistant, high-temperature resistant, and has high photoelectric conversion efficiency. The life of the concentrating cavity (8-10 years) and the life of the xenon lamp are more than 8 million times.

5. The matching hood can eliminate eye irritation during work.

6. It has the ability to work continuously for 24 hours, and the performance of the whole machine is stable.

Details of jewelry laser spot welding machine

1. Humanized design

It adopts the latest European portable mini design, scientific and streamlined mechanical structure, high-grade alloy chassis, anti-static, anti-rust, easy to move, and saves space.

2. Observevation microscope

China's top-quality high-precision microscope (10×/20 times) is used for precise positioning and welding process.

3. Controlling screen

Built-in touch screen control system with high sensitivity and convenient parameter setting. Users can set different parameters (current, frequency, pulse...) according to different materials

4. Laser optical path

The Morgan brand optical cavity imported from the UK is used to protect the laser source and prolong the service life.

It adopts Beijing famous brand crystil rod, designed by China's 11th Academy of Sciences, which is durable and not easy to damage.

5. Laser xenon lamp

Adopt Chinese top brand original xenon lamp.

Lifespan: 8 million times, taking working 8 hours a day as an example, a lamp can be used for 6-12 months.

The xenon lamp is the power source of the laser, when the xenon lamp is used up, just replace it with a new one.

6. Joystick

When the user is performing welding work, he can also adjust the position of the cursor and set parameters by moving the joystick. (emergency top/joystick/brightness)

7. LED lights

Users can adjust the brightness of the led light according to the comfort of the eyes.

8. Gas pipe

In order to ensure clean welding, it is necessary to blow argon to protect the welding surface.

9. Working table

The internal working space is large and the angle of manpower is flexible.

10. Exhaust fan

There is an exhaust fan on the back to help with cooling. There is a water cooling system inside the machine.
