Precautions for the use of soldering iron
Many electric soldering iron life itself is very long, due to some wrong methods, resulting in its life become very short. The following to the author's personal experience, to introduce the use of the soldering iron in the process of attention.
1, finished in time to unplug the soldering iron
Many people in the use of the soldering iron, but also let the iron in the heating state, this time the iron head in the heating high temperature state, it is easy to be oxidised. Once the soldering iron head is oxidised, the next use will be more difficult. Therefore, you need to do in the process of using, unplug the soldering iron in time.
2, soldering iron head tinned
I don't know if you have the habit of tinning, I always keep a tinned habit. Because after the use of the soldering iron, if not for the soldering iron head tinned, the soldering iron head will be oxidised due to high temperature, some directly appear black, affecting the normal use of the soldering iron next time.
3, do not use acidic flux
In order to solder more convenient, some users will use some flux. Most of these fluxes are acidic, high temperature corrosion of the iron head is very serious.
The best flux is rosin, to make full use of rosin this flux. Rosin can be crushed into a powder and mixed with alcohol, they can be used as a flux, the effect is very good. (25% of rosin dissolved in 75% alcohol)
4, the choice of solder
You can't go wrong with a penny for a penny. Buy a good solder wire can not only fast welding, for the soldering iron head is also better. And some not so good solder wire, easy to appear solder joints are not smooth, burrs, solder joints are not solid.
