With the development and progress of global society, the demand for electronic products is increasing. Of course, the demand for electronic products is also higher, but in fact, the battery spot welder is also one of our commonly used electronic equipment. With the increasing demand for electronic products, many young people go back to their hometown to develop their own small lithium battery assembly equipment processing plant, or to process lithium battery pack.

As a result, the company is facing more and more production costs and recruitment difficulties, and production quality cannot be guaranteed, especially for electronic welding parts. For example, manual welding of electronic products can not guarantee the "consistency" of welding products, prone to high welding failure rate, low production efficiency, these factors directly destroyed many small and medium-sized enterprises. When the battery spot welder adopts the principle of double-sided double-point overflow welding, the two electrodes pressurize the workpiece under the pressure of the two electrodes, so that the two layers of metal form a certain contact resistance. When the welding current flows from one electrode to the other electrode, the instantaneous heat fusion is formed at the two contact resistance points, and the welding current flows from the other electrode to the two workpieces immediately to form a circuit, which will not damage the workpieces and internal structure.

According to the current lithium battery spot welding machine market, the basic characteristics of general lithium battery spot welding machine parameters are as follows:

1. Digital setting of welding parameters, clear keyboard operation, convenient and simple operation.

2. 10 groups of parameters are stored to facilitate switching of various welding varieties.

3. Welding current locking technology to prevent grid voltage fluctuation from affecting welding current.

4. The inverter bridge adopts soft switching technology to reduce switching loss and EMI.

5. Sound and light alarm for abnormal current to effectively prevent false welding and false welding
