The intermediate frequency transformerindependently developed on the basis of introducing and digesting advancedsimilar products from Europe, with intermediate frequency inverter DCtechnology. The series of welding transformers are made of high-quality siliconsteel sheets and use integral punching process. The primary coil, the secondarycoil and the silicon steel sheets generally are made by the advanced vacuumepoxy resin pouring process, which has the advantages of strong insulation,high temperature resistance, low temperature rise, light weight, small volume,fast heat dissipation, safety and durability, etc.

The cooling method of the intermediate frequency transformer is water-cooled.It is equipped with three temperature control switches to detect the primarycoil, secondary coil and diode respectively. Compared with the power frequencytransformer, the transformer is lighter in weight, smaller in size, larger incurrent, more energy-saving and environmentally friendly, and more stable inperformance.
