Characteristics of intermediate frequency spot welding machine
Welding transformer is small in size, large in output energy and widely used. The advantages of integrated transformer speed welding pliers used in automobile industry are more obvious. Its superior performance is that the frequency of welding transformer is increased from 50/60Hz to 1000Hz, which greatly reduces the weight of iron core material. The rectifier diode in the secondary circuit of transformer converts electric energy into DC power supply for welding. This can greatly improve the inductance of the secondary circuit, and the inductance of the secondary circuit is an important factor causing energy loss, which can be almost ignored in DC welding circuit, thus minimizing the production cost. Compared with ordinary AC resistance welding machine, it has the following advantages:
Energy saving: compared with using low frequency, it can reduce the consumption of electric energy, and the transformer with the same weight can output more energy, which can be conveniently used with large automatic electrode holders. Suitable for welding thick workpieces and highly conductive metals. Such as aluminum and all galvanized steel plates. Generally speaking, the system with small volume and light weight can accelerate the movement and shorten the working cycle, which is the best supporting scheme for welding machine/automatic machine.
In semi-automatic device, one medium frequency welding transformer can replace many low frequency transformers, which reduces the parallel connection of secondary circuits.
If the integrated manual electrode holder weighs more than 80 to 90 kilograms, it is also suitable for this transformer. For example, small-scale production of cars/vans and small-scale manufacturing of experimental machinery and equipment.
Improve the power factor and reduce the production cost.
Interference can be reduced in the secondary circuit with large opening area: the welding current is DC, and when there is inductance/magnetic material in the secondary winding, it will not affect the welding.
Balance the load of power supply equipment: the medium frequency inverter spot welding machine adopts three-phase power supply and can store energy.
It is more suitable for the fluctuation and voltage drop of the power grid: a part of energy is stored by the inverter and then supplied to the load, instead of directly supplying power from the power grid to the load.
