The development of technology drives the progress of welding technology. Many existing welding machines and inverter DC spot welding machines are quite popular, but do you know what the characteristics of this spot welding machine are? Let ’s learn the following with the editor of the Kunming spot welding machine manufacturer. content:
Small and lightweight welding transformers. This is the result of increasing the input frequency of the transformer, which greatly reduces the cross section of the transformer core, and its size and weight are small and lightweight. Some data show that the weight of the inverter spot welding machine is 1/5 ~ 1/3 of the ordinary industrial frequency spot welding machine with the same capacity. As a result of the small size and light weight of the transformer, the integration of spot welding clamps and transformers together with the secondary rectifier can be used for spot welding robots, making spot welding production highly automated and unmanned.
1. High-speed precision control. Because the inverter spot welding machine's inverter frequency is about 20 times the power frequency of 50Hz, the response speed and control resolution of the entire feedback system are much better than the power frequency spot welding machine, which is conducive to the control of welding quality. Moreover, the inverter rectification method can make the welding time not limited by the frequency of the power frequency, make the welding time control more accurate, and can also easily achieve more precise welding current amplitude control.
2. Output low-pulse-rate direct current. The output welding current is direct current, and it has the same characteristics as the secondary rectification resistance welding machine in terms of technology. Concentration, small shunt and high thermal efficiency. Three-phase balanced load, high power factor, energy saving and economy.
At present, it is mainly used in automobile manufacturing and precision electronic parts in spot welding. Transistor power supplies are more commonly used in electronic parts. It is also used in industries such as light industrial appliances and precision auto parts. In the current market of spot welders in China, precision spot welders are still the leading products, followed by secondary rectification and battery spot welders, and precision inverter spot welders, which have developed rapidly in China in recent years. It has the advantages of short welding time, high thermal efficiency, energy saving, good welding quality, not easy to spatter, and small size and light weight of welding transformer. It will become the mainstream product in the spot welding machine industry in the future.
