Common Failures of Soldering Irons
1, the soldering iron does not heat up after energization
Soldering iron does not heat up after energized that the soldering iron has a broken circuit fault, this failure may occur in several places at the plug of the soldering iron, the soldering iron core is bad, the lead of the soldering iron core is disconnected, the power cord of the soldering iron is disconnected.
2, the soldering iron head does not eat tin
Soldering iron head does not eat "tin Park see the newly purchased iron head without trimming directly use, resulting in the iron head does not on the tin. Prolonged use of the soldering iron head is not on the tin, soldering iron head. Burned to death to make up, need to trim it.
3, electric iron charged
Soldering iron charged on the welding personnel is very dangerous, serious will lead to electric shock accident, so once found the phenomenon of electric soldering iron charged should immediately cut off the power supply to check. There are several reasons for the soldering iron charged soldering iron power cord connected to the grounding wire terminal; power cord from the soldering iron core terminal off and then touch the grounding wire screws, resulting in the soldering iron head charged power lead winding caused by leakage; power supply ground itself leakage.
4、Soldering iron head pit
When the soldering iron used for some time, the soldering iron head will appear pits, or oxidation corrosion layer, so that the shape of the edge of the soldering iron head has changed. When encountering such a situation, can file the oxidized layer and pits filed off, and filed into the original shape, and then plated with tin, can be reused.
