Product Description

The medium frequency inverter resistance spot welding machine stands as a pinnacle of advanced welding technology. Revered across multiple industries, its compact yet powerful welding transformers generate exceptional energy output. Particularly within the automotive sector, the integrated transformer quick welding tongs shine with unparalleled efficiency. This remarkable performance is owed to elevating the welding transformer frequency from the standard 50/60Hz to a robust 1000Hz, significantly reducing the iron core weight. Moreover, a rectifier diode in the transformer's secondary circuit masterfully converts electrical energy into DC power, optimizing it for welding applications.
 

Features

1. The welding current is direct current, ensuring that the presence of induction and magnetic materials within the secondary winding remains uncompromised, thereby maintaining welding integrity.
2. To equitably distribute the load across power supply equipment, this cutting-edge medium frequency inverter spot welding machine utilizes a robust three-phase power supply. This configuration is adept in handling power grid fluctuations and voltage variations with ease.
3. Experience unparalleled precision with our rapid current control capabilities; surpassing traditional power frequency systems, it delivers meticulous parameter analysis for impeccable results.
4. The medium frequency technology enables welding current adjustments at a speed 20 times faster than conventional methods, ensuring swift and efficient operations.
5. This welding innovation significantly trims operating costs by conserving energy at every weld point and considerably reducing the welding cycle duration.
6. Energy conservation is one of its hallmarks: ideally suited for welding robust workpieces and metals with high conductivity, including aluminum and all variants of galvanized steel.
