1, the rectifier diode in the secondary circuit of the transformer of the intermediate frequency spot welder converts the electrical energy into DC power supply for welding.
2, car seat adjustment bracket welding machine energy saving: with the use of frequency welding machine can reduce the consumption of electricity, energy saving of more than 50%, the same weight of the transformer can output more energy, suitable for welding thick workpieces and high conductivity of the metal.
3, improve the power factor, reduce production costs.
4, automotive seat adjustment bracket welding machine precise, fast current control, compared with the frequency system can be more and more accurate analysis of parameters.
5, medium frequency spot welder welding current for DC, when the secondary winding has induction / magnetic material, will not affect the welding.
6, so that the load balance of the power supply equipment: medium frequency inverter DC welding power supply using three-phase power.
