Mf220 Galvanized Sheet Welding Transformer

Product Description

Application 

For all kinds of intermediate frequency, power frequency resistance welding machine.Such as automobile welding clamp,

seam welding machine, mesh welding machine, and so on.

Brief introduction 

Medium-frequency (MF) transformers are a result of recent advances in resistance welding technology. 

They are powered by a transistor inverter, supplying square wave AC 500 V @ 1000 Hz which is converted by the MF transformer to a low voltage high current AC.

This low voltage AC current is rectified to DC by a diode block built into the transformer.

The higher operating frequency of an MF system allows efficient energy conversion using a smaller and lighter transformer.

Other benefits with MF transformers used in portable and robotic welding guns are:

The reactance of the welding loop only limits the upslope and downslope of the welding current.

While the peak welding current is limited only by the welding loop's resistance. 

The net result is again a smaller transformer, especially when welding with the large throat, high-impedance guns.

MF welding is less demanding on the plant power system.

The MF inverter draws a balanced line current from all 3 phases and operates at a high power factor (0.9).

With MF transformers the peak welding current almost equals its RMS value, which helps to obtain quality welds with no splash and constant strength even at lower pressure.

The high frequency permits much faster - 1000 times per second - process control, which again results in better weld quality.
