Do you know what are the common faults of electric soldering irons?
1. The electric soldering iron does not heat up after being energized
If the soldering iron does not heat up after being energized, it means that the soldering iron has an open circuit fault. This fault may occur at the plug of the soldering iron in several places. The soldering iron core is broken, the lead wire of the soldering iron core is broken, and the power cord of the soldering iron is broken.
2. The tip of the soldering iron does not eat tin
Soldering iron tip does not eat "Tin Pu sees that the newly bought soldering iron tip is used directly without repairing, resulting in no tinning of the soldering iron tip. The soldering iron tip that has been used for a long time is not tinned, and the soldering iron tip is burnt to death and needs to be repaired.
3. The electric soldering iron is charged
A live soldering iron is very dangerous to welding personnel, and serious electric shock accidents will occur. Therefore, once the electric soldering iron is found to be live, the power supply should be cut off immediately for inspection. There are several reasons why the electric soldering iron is electrified. The power cord of the electric soldering iron is connected to the terminal of the grounding wire; the power cord falls off from the terminal of the soldering iron core and then touches the screw of the grounding wire, causing the electric power lead wire of the soldering iron head to be entangled and cause leakage; The power ground itself leaks electricity.
4. There are pits on the tip of the soldering iron
When the electric soldering iron is used for a period of time, pits or oxidized corrosion layers will appear on the tip of the soldering iron, which changes the shape of the blade surface of the soldering iron tip. In this case, the oxide layer and pits can be filed off with a file, and filed into the original shape, and then tinned, and then it can be reused.
