Product Description

The medium frequency inverter resistance spot welding machine stands at the forefront of welding technology as an advanced piece of equipment. This remarkable machine finds its purpose across various domains, celebrated for its compact yet high-output energy welding transformers. Especially in the automotive sector, the integrated transformer quick welding tongs offer unparalleled advantages. Its exceptional efficiency is derived from elevating the welding transformer frequency from the conventional 50/60Hz to an impressive 1000Hz, significantly lightening the iron core's weight. Moreover, the rectifier diode within the transformer's secondary circuit ingeniously transforms electrical energy into DC power, optimized for welding applications.
 

Features

1. With a direct current welding current, the presence of induction and magnetic materials in the secondary winding does not impede the welding process.
2. To harmonize the power supply load, the medium frequency inverter spot projection welding machine utilizes a robust three-phase power source, offering enhanced resilience to power grid fluctuations and voltage drops.
3. Experience unprecedented precision and speed in current control; compared to traditional power frequency systems, it offers superior parameter analysis.
4. Medium frequency technology allows for adjusting the welding current up to 20 times faster than traditional methods, ensuring peak performance.
5. Welding operations are cost-efficient, conserving energy at every welding point and significantly reducing welding cycle times.
6. Emphasizing energy efficiency: Especially advantageous for welding thick workpieces and metals with high conductivity, such as aluminum and all varieties of galvanized steel plates.
