Electrode head has always been the biggest vulnerable part in the use of spot welding machine, so how should users maintain the electrode when using medium frequency spot welding machine, and how should we repair the electrode of spot welding machine when the electrode is slightly deformed? Today we will give some suggestions on electrode repair of spot welding machine, hoping to help you.　

1. During the welding and cutting operation of the energy storage spot welder, all the inflammable and explosive materials within the scope of 1 om of the working environment shall be cleaned up. Attention shall be paid to whether there are flammable liquids and gases in the trenches and sewers of the working environment, and whether there is the possibility of leakage of inflammable and explosive materials into the trenches and sewers, so as to avoid disasters and accidents caused by welding slag and metal sparks. 2. During high altitude welding and cutting, it is forbidden to throw the electrode head around. The lower part of the welding and cutting operation shall be isolated. After the operation, careful inspection shall be carried out and no fire hazard shall be confirmed before leaving the site. 3. Gas cylinders that meet the requirements of relevant national standards and regulations shall be used, and safe operation regulations shall be strictly observed in the storage, transportation, use and other links of gas cylinders.　

What is the direct benefit of medium frequency spot welding machine for enterprises? Many people are not easy to consider the place, often more simple and clear is also easy to be ignored by everyone, "energy saving", so let's see how to save electricity. As follows:　

1. The surface of the welding object may be unclean, not cleaned or not cleaned. When using the spot welder, pay attention to the cleaning of the working parts of the spot welder, so that the welding will be better. 2. It is possible that the uneven pressure distribution on the contact surface between the spot welding machine and the welding object results in the high local current density, which leads to the early melting of the welding object and the generation of spatter. So how to prevent large sparks in the early stage of spot welding? 1. We need to strengthen the cleaning of spot welding machine. Before and after each use, we need to clean the working table and welding objects of spot welding machine to ensure the cleanness of welding objects.　

1. Before operation, the oil stains on the upper and lower electrodes shall be removed. After power on, the body shell shall be free of leakage. 2. Before starting, turn on the steering switch of the control circuit and the small switch of the welding current, adjust the number of poles, then turn on the water source and air source, and finally turn on the power supply. 3. After the welding machine is powered on, check the electrical equipment, operating mechanism, cooling system, air circuit system and body shell for leakage. The electrode contact shall be bright. In case of leakage, it shall be replaced immediately. 4. During operation, the air circuit and water cooling system shall be unblocked. The gas should be dry. The drainage temperature shall not exceed 40 ℃, and the drainage volume can be adjusted according to the temperature.　

In the 1990s, China's welding industry took the realization of mechanization and automation of welding process as a strategic goal, which has been put into practice in the scientific and technological development of various industries. It is developing the automation of welding production, researching and developing the welding production line and flexible manufacturing technology, and developing the application of computer-aided design and manufacturing. Among them, the growth of flux cored wire has increased significantly in the next 20 years It will surpass solid core welding wire and eventually become the leading product of welding center.　

Because the heat generated by resistance is directly proportional to the square of current, the welding current of medium frequency spot welder is the most important factor of heat generation. The importance of welding current is not only the magnitude of welding current, but also the magnitude of current density.　

The products of many industries can't be integrated. They need to be welded later. We need to use stainless steel spot welder to weld. When using stainless steel spot welder to weld workpiece, the choice of electrode material and shape is very important, which directly determines the welding effect.
