Product Description

The medium frequency inverter resistance spot welding machine is a pinnacle of cutting-edge welding technology. It stands out for its exceptional versatility and efficiency, boasting compact welding transformers that deliver immense energy output. Particularly beneficial in the automotive sector, the integrated transformer with quick welding tongs showcases unmatched performance, thanks to the elevation of welding transformer frequency from 50/60Hz to an impressive 1000Hz. This innovative enhancement significantly diminishes the iron core's weight. Additionally, the inclusion of a rectifier diode in the transformer's secondary circuit ingeniously converts electrical energy into DC power, optimizing its use for welding applications.
 

Features

1. The welding current flows as direct current, ensuring that the presence of induction and magnetic materials in the secondary winding remains non-intrusive to the welding process.
2. To harmonize the power supply equipment's load, the medium frequency inverter point projection welding machine utilizes a robust three-phase power supply. This design enhances its resilience to power grid fluctuations and voltage drops, ensuring reliable performance.
3. Experience more precise and rapid current control capabilities; compared to traditional power frequency systems, this advancement allows for a more accurate analysis of welding parameters.
4. With medium frequency technology, welding current adjustments occur 20 times faster than with conventional techniques, offering unparalleled swiftness and adaptability.
5. Enjoy reduced welding operating costs, as each welding point becomes more energy-efficient and the welding cycle significantly shorter.
6. Energy Efficiency: This system excels in welding thick workpieces and metals with high conductivity, like aluminum and all galvanized steel plates, making it an ideal choice for demanding applications.
