Methods to reduce the oxidation rate of the tip and core of the soldering iron
1、Test resistance size
Before using the soldering iron, measure the resistance of the power plug to determine whether the soldering iron is available.
The resistance of the soldering iron is a few thousand ohms, indicating that it is available. If the resistance is zero or infinity, it can not be used. Resistance is zero, it indicates that there is a short circuit inside the soldering iron, resistance infinity, that there is a broken circuit inside the soldering iron.
2, tinned protection
When the new soldering iron first use, ensure that the soldering iron head is bright, power heating melting solder while dipping rosin, many times in contact with the solder wire, the soldering iron head evenly coated with a layer of solder. Can be easy to follow the use, but also can prevent the soldering iron head oxidation.
Old soldering iron has been used for a long time, the surface of the iron head will have a layer of oxide, resulting in the iron head is not easy to eat tin.
You can use fine sandpaper or file to remove the oxides on the surface of the soldering iron head, so that its surface becomes bright. Then, in accordance with the new soldering iron treatment, the soldering iron head surface evenly plated with a layer of welding.
3, the soldering iron does not eat tin
When the soldering iron does not eat tin problem, generally do not need to consider whether the oxygen is insufficient to cause, oxygen and soldering iron heating nothing related to the soldering iron through the alternating current and heating melting solder wire.
Soldering iron does not eat tin, because the soldering iron is energized for too long without use, it will accelerate the soldering iron core oxidation and burn off, shorten its service life. At the same time, it will lead to long time heating and oxidization or burnt iron head.
This leads to the problem of the soldering iron does not eat tin occurs, in the process of not eating tin oxidation reaction occurs, the substance and oxygen occurred
A chemical reaction occurs, in which oxygen provides oxygen.
In the case of too long a time of energization, the temperature rises sharply, giving the oxidation reaction provides the reaction conditions, it will accelerate the oxidation speed of the soldering iron iron tip and the soldering iron core.
