Medium frequency DC inverter spot projection welding machine

>Series medium frequency DC inverter spot bump welding machine series medium frequency inverter spot bump resistance welding machine is a set of advanced welding equipment. Widely used, the welding transformer is small in size and has large output energy. Its advantages are even more obvious when used in the automotive industry as a one-piece transformer welding clamp. Its superior performance is due to the fact that the frequency of the welding transformer has been increased from the current commercial power supply, which greatly reduces the weight of the core material. In addition, the rectifier diode in the secondary circuit of the transformer converts electrical energy into DC power for welding use. This can greatly improve the secondary loop inductance value, thereby minimizing production costs.
In the secondary circuit with a large open area, it can reduce the interference in the welding and turn it into a tributary when there are inductive/magnetic materials in the secondary winding. Will not affect welding.
The medium frequency inverter spot welding machine uses a three-phase power supply and can store energy to balance the load of the power supply equipment.
More adaptable to grid fluctuations and voltage drops. Part of the energy is stored by the inverter and then supplied to the load, replacing the direct supply of power to the load from the grid.
More accurate and fast current control can analyze more parameters more accurately than the power frequency system.
Achieving the set current faster. The intermediate frequency can adjust the welding current twice as fast as traditional technology.
The process is more reliable. Most metals that are subject to group welding will have better results if they are tributary welded.
Reduce operating costs, including saving energy at each point of welding and shortening the welding cycle.
Saving energy Compared with using power frequency, it can reduce the consumption of electric energy and is used for welding thick workpieces and highly conductive metals. Such as aluminum and all zinc-clad steel plates, etc.
