Four common faults of electric soldering iron
1. No heat after power on
If the soldering iron does not heat up after being energized, it means that the soldering iron has an open circuit fault, and the fault point is not fixed and may be scattered in multiple places. The power cord is disconnected, etc.
2. The tip of the soldering iron does not eat tin
The soldering iron tip does not eat tin, and the newly purchased soldering iron tip is used directly without trimming, which will cause the soldering iron tip to not be tinned. The tip of the soldering iron that has been used for a long time is not tinned, and the tip of the soldering iron is burnt out, requiring maintenance.
3. The electric soldering iron is charged
Electric soldering iron is very dangerous for soldering personnel, and it will lead to electric shock accidents in severe cases.
When the electric soldering iron is found to be charged, immediately cut off the power supply, and then check it.
There are several reasons why the electric soldering iron is electrified. The power cord is connected to the terminal of the grounding wire. The power cord falls off from the terminal of the soldering iron core and touches the screw of the grounding wire. The line itself leaks electricity, etc.
4. There are pits on the tip of the soldering iron
After the electric soldering iron is used for a period of time, pits or oxidized corrosion layers may appear on the tip of the soldering iron, which changes the shape of the blade surface of the soldering iron tip.
Solution: Use a file to file off the oxide layer and pits, file it into the original shape, and then tin-plate it to resume use.
