Common electric soldering iron issues
1. The electric soldering iron does not heat up after being energized
If the soldering iron does not heat up after being powered on, 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
Do not eat soldering iron tip "Tin Pu sees that the newly purchased soldering iron tip is used directly without trimming, 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
Electric soldering iron is very dangerous for welding personnel, and serious electric shock accidents will occur. Therefore, once the electric soldering iron is found to be electrified, 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 soldering iron tip, 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.
How long does a soldering iron heat up
The power of a 60w soldering iron is very high, but the soldering iron generally needs to be preheated for 3-5 minutes. Although you may see it getting hot and smoking, it may not have reached the melting point of solder. The warm-up time of the soldering iron is also related to the use environment. The warm-up time will be longer in an environment with high wind and low temperature. It is recommended to take some protective measures for the soldering iron (such as adding a sleeve) to ensure that the soldering iron can last. Gather heat to reach a certain high temperature.
The new electric soldering iron will have a little smoke and peculiar smell when used for the first time. There is a layer of anti-oxidation paint on the soldering iron, which should be wiped off gently before use. For the first use, the solder should be fully fed to the tip of the soldering iron, so that it can fully absorb the tin and then solder.
