Detail Information

CONNUC medium frequency inverter welding machine overview:

It is advanced welding quipment with core componnets includinginverter, welding controller, middle frequency transformer. It uses module design, uses imported electronic elements and equipped with micro-computer multi function controller. The controller uses 8-bit micro computer as heart,together with 2 groups analog/digital conversion circuit, so it canautomatially control power voltage changement & surrounding temperature change to ensure stable output, so to reach the best welding quality.

The machine has three momorizing function, easy setting and operation,suprior quality, very small fault, with reliable long term working. 

The machine has small measurement transformer but with big output engery, it can increase the electricity networks’ 50/60hz to 1000Hz, maximumly reduced the steel core weight, Also the rectifier diodes in the secondary circuit can switch power to DC for welding machine, so it greatly improved the secondary loo inductance value which lead to engery lossing, so it reduces production cost to minimum.




1.      DC welding current, when secondary windnigs have inductive/magnetic material it will not affect the welding.

2.      Make the power supply device with balance loading, the intermediate frequency inverter welding machine uses 3 phase power supply but with strong adaptability for power grid voltage fluctuation and voltage step down.

3.      More precise & faster current controlling, more numbers & more accurate analysis parameters compared with power frequency system.

4.      Faster reaching to setting current, 20 times faster than conventional technology.

5.      More reliable process, majority of resistance welding metals will get better welding quality if by DC welding.

6.      Cost saving,reduces every spot welding energy and shorts welding period.

7.      Energy saving, especially very suitable for welding thick working piece and high conductive metals, such as aluminum & all galvanized steel sheet, copper wire & copper plate etc.,
