Product Description

Medium frequency inverter spot projection welding machine is a set of advanced welding equipment. Widely used, welding transformers have a small volume and large output energy. The advantages of portable spot welding machines used in the automotive industry are even more evident. Its superior performance is due to the increase in the frequency of its welding transformer from 50/60Hz to 1000Hz, which greatly reduces the weight of the iron core material. In addition, the rectifier diode in the secondary circuit of the transformer converts electrical energy into DC power for welding. This can greatly improve the value of the secondary circuit inductance coefficient, which is an important factor leading to energy loss and can almost be ignored in DC welding circuits, thereby minimizing production costs.

Main Features

Compared with ordinary AC resistance welding machines, it has the following advantages:

1. Energy saving: Compared to using low frequency, it can reduce the consumption of electric energy. A transformer with the same weight can output more energy, which can be easily used with large automatic welding tongs. Suitable for welding thick workpieces and highly conductive metals. Such as aluminum and all galvanized steel plates. Generally speaking, small and lightweight systems can accelerate movement and shorten work cycles, making them the best matching solution for welding machines/robots.

2. Improve power factor and reduce production costs.

3. Interference can be reduced in the secondary circuit with a large opening area: the welding current is DC, and when there is inductive/magnetic material in the secondary winding, it will not affect welding.4. Balance the load of power supply equipment: The intermediate frequency inverter spot projection welding machine uses three-phase power supply and can store energy.5. Greater adaptability to grid fluctuations and voltage drops: A portion of energy is stored by the inverter and then fed to the load, replacing the method of directly supplying power to the load from the grid.6. More accurate and fast current control: More and more accurate analysis of parameters compared to low-frequency systems.7.Faster reaching the set current: The intermediate frequency can adjust the welding current 20 times faster than traditional technology.8. More reliable process: DC welding is better for most metals that apply resistance welding.9. Intermediate frequency systems are generally more reliable than traditional technologies and can avoid some damage that can lead to damage to thyristor based systems.10. Reduce operating costs, including saving welding energy at each point and shortening the welding cycle.
