With the rapid development of the world's manufacturing industry, the application of welding technology has become more and more extensive, and the level of welding technology has also become higher and higher. New welding process methods are constantly emerging, and professional welding equipment is changing with each passing day. Speaking of welding technology, I have to mention the inverter spot welding machine.

　　1. Several aspects of the development of inverter welding machine in depth

　　① Increase in popularity:

　　The participation rate of inverter welding machines is getting higher and higher, and the number of exhibitors is getting wider and wider. In previous years’ exhibitions, almost all major companies exhibited various inverter welding machines and new technologies and products in a larger position, but their varieties, powers, performances, functions and manufacturing levels were different. . In addition, the variety, performance, function, welding method and application range of inverter welding machines have also been improved, increased and expanded.

　　②Enhanced power manufacturing capacity:

　　In the past, it was believed that the inverter welding machine was mainly suitable for small and medium power occasions with its advantages of small size, convenient movement, energy saving and material saving.

　　③Miniaturization:

　　By increasing the frequency, using high-performance magnets, optimizing the structure, etc., the low-power inverter welding machine should be made as small as possible. For example, the small welding machine used for thin plate welding in the assembly and maintenance work where the welding position changes frequently is only 3.4kg.

　　Working principle of inverter spot welding machine

　　Inverter spot welding machine is mainly an inverter arc welding power source generated by an inverter, also known as an arc welding inverter, which is a new type of welding power source.

　　2. Working process of inverter welding machine

　　Inverter spot welding machine is to rectify three-phase or single-phase power frequency alternating current, and obtain a smoother direct current after filtering. The inverter circuit composed of IGBTs converts the direct current into tens of KHZ alternating current, which is stepped down by the main transformer After that, it is rectified and filtered to obtain a stable DC output welding current.
