Precautions for the operation method of pe electric welding machine

The oxide layer must be removed, and the pipe inserted into the pipe fitting should be loose and tight. Generally, it is better to be easily inserted. During welding, the embedded resistance wire may be squeezed together to form a short circuit due to the extrusion force during the melting process of the pe material. Therefore, the resistance value becomes smaller. The current increases and the resistance wire heats up sharply. In order to save time during construction, the result of inserting the too tight pipe/pipe fitting too tightly. As a result, the pipe fittings are melted at high temperature, which is why the molten material is sprayed out during the electric melting process. In another case, the extrusion will reduce the spacing between the resistance wires and cause the temperature to increase sharply.
