The electrofusion welding machineuses the high-temperature arc generated by the instantaneous short circuit between the positive and negative poles to melt the solder and the material to be welded on the electrode and combine the objects to be contacted. Its structure is very simple, which is a high-power transformer. According to the type of output power supply, electrofusion welding machine can be divided into two types: AC power supply and DC power supply.

Common maintenance methods for inverter welding machines
1. Resistance method.
It is to use a multimeter to measure the resistance value of each device in the electrofusion welding machine. Check whether there is a short circuit or open circuit in the circuit. For example, whether the resistance is damaged by changing value, the capacitance is out of capacity, the transistor is broken down and damaged, short circuit or open circuit, etc. This method is the simplest and most commonly used, and is suitable for preliminary fault judgments of resistors, capacitors, inductors, transistors, integrated circuits, etc.
2. Voltage method.
It is to measure whether the working voltage of each working point of the electrofusion welding machine is normal when the circuit is powered on. This method requires familiarity with the circuit. But its measurement and judgment result will be more accurate.
3. Replacement method.
It is a method of judging and troubleshooting some components in the electrofusion welding machine that cannot be determined to be normal or not, and replace them with good components. This method is generally used on machines that can roughly determine the fault location, and it is generally used as a follow-up judgment method for the resistance method.
The electrofusion welding machine uses electric energy to instantly convert electric energy into heat energy. Electricity is very common. The electrofusion welding machine is suitable for working in a dry environment and does not need too many requirements. It is widely used in various fields due to its small size, simple operation, convenient use, fast speed and strong weld after welding, especially for products requiring high strength, The same metal material (or different metals can be connected, but the welding methods are different) can be permanently connected. After heat treatment, the weld has the same strength as the base metal and has good sealing, which solves the problems of sealing and strength for the manufacture of gas and liquid storage containers.
The use specification of electrofusion welding machine requires that the oxide layer is to be removed. During welding, special fixing fixtures are required to fix the pipe to prevent the stress on the melting area caused by the temperature rise during the welding process. The electric fuse is squeezed when it is relieved The phenomenon of dynamic displacement and short circuit occurs, which causes the welding failure of the electrofusion welding machine. The phenomenon of black mist and smoke emission from the fused casing during welding encountered during welding is mostly caused by failure to fix.
