Main Features

1. High efficiency and energy saving: The conversion efficiency of intermediate frequency inverter technology is over 90%, which saves 30% -50% energy compared to traditional power frequency welding machines and reduces power grid load; Short welding time (in milliseconds) significantly improves production efficiency.

2. Excellent welding quality: stable intermediate frequency DC output, uniform formation of fusion nuclei, reduced spatter and virtual welding, high weld strength, and smooth appearance; Suitable for welding high conductivity materials (such as aluminum, copper) and multi-layer plates.

3. Intelligent control: Digital PLC or microprocessor control, can accurately adjust parameters such as current, time, pressure, etc., supports multiple sets of program storage; Equipped with automatic compensation function to offset the impact of power grid fluctuations or workpiece surface oxidation.

4. Automation integration: can be combined with robotic arms and conveyor belts to achieve fully automated production, suitable for assembly line operations; Equipped with photoelectric sensors or vision systems to accurately locate the position of solder joints.

5. Durable and low maintenance: Medium frequency transformers have small volume, low heat generation, and long service life; The water cooling system ensures the continuous and stable operation of the equipment.

6. Application scope:
Automotive industry: door hinges, seat frames, battery connectors, etc.
Hardware: Nut/bolt projection welding, metal mesh welding.
Home appliances: metal shells, brackets, and other point welding processing.

Customized Fixtures and Moving Components
The section mainly consists of fixtures and moving components. Manually replacing fixtures can achieve welding of two different workpieces. During welding, the workpiece can move back, forth, left, and right on the moving component. Each type of workpiece is completed in four stages, with the first three stages being projection welding and the fourth stage being spot welding.




Gas Storage Tanks
The projection and spot welding machine is equipped with a dedicated gas storage tank, which is beneficial for reducing welding pressure fluctuations and ensuring stable welding force.
