Common Malfunctions of Soldering Irons
1. The soldering iron does not generate heat after being powered on
If the soldering iron does not heat up after being powered on, it indicates that the soldering iron has an open circuit fault. This fault may occur in several places, such as the soldering iron plug, the soldering iron core is broken, the soldering iron core lead is open, and the soldering iron power cord is open
2. The soldering iron tip does not eat tin
The soldering iron tip does not eat "Xipu saw that the newly purchased soldering iron tip was used directly without repair, resulting in the soldering iron tip not being tinned. The soldering iron tip that was used for a long time was not tinned, and the soldering iron tip was burned and repaired, requiring repair.
3. Electric soldering iron charged
Electrified soldering iron is very dangerous for welding personnel, and serious cases can lead to electric shock accidents. Therefore, once the phenomenon of electrified soldering iron is discovered, the power should be immediately cut off for inspection. There are several reasons why an electric soldering iron can be charged. The power cord of the soldering iron is connected to the terminal of the grounding wire; The power cord detached from the soldering iron core terminal and then touched the screw of the grounding wire, causing the live power lead of the soldering iron tip to entangle and cause leakage; The power ground wire itself is leaking electricity.
4. The soldering iron tip has dents
After using an electric soldering iron for a period of time, the tip of the iron will develop pits or oxidation corrosion layers, causing changes in the shape of the blade surface of the soldering iron tip. When encountering this situation, you can use a file to remove the oxide layer and pits, and file them back to their original shape, then tin them and they can be reused.
