3. The continuous load rate of transformer is low and the work is discontinuous;
4. High transmission power of transformer;
5. The working frequency is 1KHZ;
6. The output is DC, the inductance of the secondary circuit is small, and the thermal efficiency is greatly improved;
7. The output is DC. Due to the beam collection effect of DC, the welding heat can be concentrated and the heat affected zone around the solder joint can be reduced. This feature is particularly important for the welding of multilayer plates and thick plates;
8. The magnetic core of intermediate frequency transformer is made of nano amorphous iron base strip. Nanometer amorphous iron based materials have the advantages of high magnetic flux density, high permeability, high Curie temperature and high thermal stability, as well as small eddy current loss, low iron loss and high magnetic induction strength.
