Why is there electrification in welding head? What is the impact

Welding head is an accessory product of electric soldering iron, electric soldering iron and welding table. When new electric soldering iron is first used, it needs to be tin-plated in welding head, so as to make welding flow better. Sometimes there is electrification in welding head. Why? Will there be any bad influence?

　　In addition to the wrong connection of the power cord to the grounding wire terminal, there is another reason why the power cord falls from the soldering iron core terminal and then touches the screw of the grounding wire, and then the welding head is charged. This kind of trouble can easily lead to electric shock accidents and damage components. To prevent the power cord from falling, check whether the wire pressing screw on the handle of the soldering iron is loose or lost. If it is loose or lost, it should be matched in time. Inductive voltage, connected with alternating current, is lost if it is grounded well. If it is not grounded, use the low-voltage soldering iron of iron core transformer. If led is burned, it may leak electricity or the induced voltage is too high.

　　The ground wire of welding head is grounded through cold ground screws. If this ground wire is grounded alone but not through cold ground, if the welding platform is inserted in two ways, the grounding end of the welding platform must be safely grounded. If it is a triangle plug, the ground wire of the triangle plug must be grounded. The led lamp bead is welded with a soldering iron, which should be a 220v soldering iron without grounding. the induced voltage on the welding head is very high, and the led voltage is generally between 1.5 and 3.5, so it is easy to break down the led chip.
