1. Introduction
The LY YAG Laser 200W Mini Jewelry Spot Welding Machine is a compact and precise tool designed for micro laser soldering, primarily used in the jewelry, hardware, and electronics industries. This machine excels in welding gold, silver, and other precious metals, as well as small electronic components and dental prosthetics. Its operation is based on heat conduction, where laser radiation heats the workpiece surface, and the heat spreads inward. By controlling parameters such as pulse width, energy, peak power, and repetition frequency, the machine precisely melts materials to form specific weld pools.
This mini version offers the same robust functionality as larger models in a smaller footprint, making it convenient for various workspaces.

6. Operating Instructions
The LY YAG Laser 200W Mini features a touch screen control for intuitive operation.
- Power On: Press the main power switch to turn on the machine. The touch screen display will illuminate.
- Parameter Adjustment: Use the touch screen interface to set the desired welding parameters:
- Output Power: Adjust the laser output power (200W max).
- Pulse Width: Set the duration of each laser pulse (0.1~20ms adjustable).
- Pulse Repeated Frequency: Configure the number of pulses per second (1~20Hz adjustable).
- Workpiece Placement: Place the item to be welded securely in the welding chamber.
- Observation: Utilize the HD CCD microscope and display to precisely position the laser spot on the welding area. Adjust focus as needed.
- Welding: Once the workpiece is correctly positioned and parameters are set, initiate the laser welding process. Follow specific instructions on the touch screen for firing the laser.
- Post-Welding: After welding, allow the workpiece to cool before handling. Inspect the weld quality using the microscope.
