Product Description

The Medium Frequency Inverter Resistance Spot Welding Machine is a cutting-edge piece of welding equipment that is gaining widespread recognition for its exceptional capabilities. Notably utilized in the automotive industry, it features compact welding transformers that deliver high output energy, making it particularly advantageous. This machine's remarkable performance is attributed to the increase in the welding transformer frequency from 50/60Hz to an impressive 1000Hz, significantly reducing the weight of the iron core. Moreover, the rectifier diode in the secondary circuit of the transformer efficiently converts electrical energy into DC power, optimized for welding.
 

Features

1. The welding current is direct current, ensuring that the presence of induction and magnetic materials in the secondary winding does not affect the welding process, maintaining consistent performance.
2. To ensure the stability of the power supply, the medium frequency inverter point projection welding machine employs a three-phase power supply. This feature enhances its adaptability to fluctuations and voltage drops in the power grid, ensuring reliable operation.
3. Enjoy more precise and rapid current control; this system outshines power frequency systems by analyzing parameters with greater accuracy, offering superior precision in every weld.
4. The medium frequency technology allows for adjusting the welding current 20 times faster than traditional methods, enabling quicker response times and more efficient welding processes.
5. Welding operations are more economical, as this technology reduces operating costs significantly by saving energy at each welding point and shortening the welding cycle, thus increasing productivity.
6. Energy-saving excellence: This machine is ideally suited for welding thick workpieces and highly conductive metals, such as aluminum and various galvanized steel plates, offering substantial energy savings.
