If in the same processing, in the case of a large number of devices that can be applied, there are still many users who prefer to use one of them, it is inevitable that this device can fully meet their own application needs relatively. For example, in terms of welding processing, the main reason why we prefer to choose intermediate frequency spot welding machine is that it can fully meet our welding needs from the following aspects:　

In the welding process of medium frequency spot welder, there are often some problems of spot welder failure and product defect rate, such as poor welding, serious spatter, material discoloration, electrode sticking, electrode loss and so on. If we analyze it carefully, we can find out some reasons and correct them. The main reasons for the failure of medium frequency spot welder are as follows:　

Single point projection welding and multi-point projection welding are designed to be spherical, cone-shaped and square, and pre pressed on thin parts or rear parts, with wide application range. Single point projection welding can be carried out on spot welding machine; multi-point projection welding can also be carried out on projection welding machine, with up to 20 welding points each time.　

The service life of energy storage spot welding machine is determined by the use mode and maintenance, and the control system of welding machine is a very important part, which is to control the welding parameters of spot welding. Once the control system is damaged, it will affect the normal production of the company. To reduce the production efficiency of the company is a small maintenance code summarized for everyone.　

The electrode of nut spot welding machine can be divided into three categories: one is good conductivity and poor strength; the other is moderate conductivity and moderate strength, which is suitable for most workpieces; the other is poor conductivity but good strength (mainly high temperature strength). Now I will introduce them to you.　

After purchasing spot welding machine, professional installation personnel shall be employed for installation, and wrong installation may affect a series of later use. The staff should be familiar with the precautions in the manual, so as to reduce the errors in the process of using the spot welder, and the correct operation method can effectively avoid accidents.　

When the energy storage nut spot welder is used for the first time, it must be preheated for several minutes. If there is smoke, it is normal, and it will disappear in a few seconds. Insert the rated tin wire from the tin inlet, and then pull the trigger in the direction of the arrow until the tin wire reaches the tin pipe mouth, then it can work normally.　

The spot welder system consists of three parts: mechanical device, power supply device and control device. So the question is, what are the characteristics of these departments? Bika welding equipment (Shanghai) Co., Ltd. will introduce them to you.
