Brief introduction 

 

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

They arepowered 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 down

slope of the welding current, while the peak welding current in limited only by the welding loop’s resistance. 

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

MF welding is less demanding on the plant power system. The MF inverter draws 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 constantstrength even at lower 

pressure.The high frequency permits much faster – 1000 times per second - process control, which again results

in better weld quality.

 

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.
