Product Description

The medium frequency inverter resistance spot welding machine stands as a cutting-edge marvel in welding technology. Renowned for its extensive application range, this equipment features compact welding transformers that deliver high-energy output. The integrated transformer quick welding tongs are particularly beneficial in the automotive industry. Its exceptional performance stems from the enhanced welding transformer frequency, increased from the traditional 50/60Hz to a robust 1000Hz. This innovation significantly reduces the iron core's weight. Moreover, the inclusion of a rectifier diode in the transformer's secondary circuit ingeniously converts electrical energy into DC power specifically for welding, optimizing efficiency.
 

Features

1. The welding current is delivered as direct current, ensuring that even with induction and magnetic materials in the secondary winding, the welding process remains unaffected.
2. To optimize power supply load balance, the medium frequency inverter point projection welding machine utilizes a three-phase power supply. This approach provides enhanced adaptability to power grid fluctuations and voltage drops.
3. Enjoy more precise and rapid current control; when compared to power frequency systems, it offers the ability to analyze parameters with greater accuracy.
4. Medium frequency technology enables welding current adjustments 20 times faster than conventional methods, revolutionizing the speed of welding operations.
5. This welding process slashes operating costs by conserving energy at each welding point and significantly shortening the welding cycle.
6. Energy efficiency is paramount, making it especially suitable for welding thick workpieces and highly conductive metals like aluminum and all varieties of galvanized steel plates.
