How to maintain an electric soldering iron?
Before carrying out welding work
You must first wet the cleaning sponge with water, and then squeeze out any excess water. This can achieve the best cleaning effect for the soldering iron tip. If a non moist cleaning sponge is used, it will damage the soldering iron tip and cause it to not solder.
The following welding sequence can provide solder protection and reduce oxidation rate for the soldering iron head during welding work.
After welding work
First, adjust the temperature to about 250 ° C, then clean the soldering iron tip, and add a layer of new tin for protection. (If using non temperature controlled soldering iron, first cut off the power and let the temperature of the soldering iron head slightly decrease before soldering.)
Try to use low-temperature welding as much as possible
High temperature can accelerate the oxidation of the soldering iron tip and reduce its lifespan. If the temperature of the soldering iron tip exceeds 470 ° C, its oxidation rate is twice that of 380 ° C.
Do not apply excessive pressure
When welding, do not apply too much pressure, otherwise it will damage and deform the soldering iron head. As long as the soldering iron tip can fully contact the solder joint, heat can be transferred. Choosing a suitable soldering iron tip can also help with heat transfer.
Regularly maintain tin on the soldering iron tip
This can reduce the chance of oxidation of the soldering iron tip, making it more durable. After use, new solder should be added only when the temperature of the soldering iron head has slightly decreased, so that the tin coating has a better anti oxidation effect.
Keep the soldering iron tip clean and immediately remove oxides
If there is black oxide on the soldering iron head, the soldering iron head may not be tinned and must be cleaned immediately. When cleaning, first adjust the temperature of the soldering iron head to about 250 ° C, then clean the soldering iron head with a cleaning sponge, and then tin it. Repeat the action continuously until the oxide is cleared.
Choose flux with low activity
Fluxes with high activity or strong corrosion will accelerate the corrosion of the soldering iron head when heated, so low corrosion fluxes should be selected.
Place the electric soldering iron on the soldering iron holder
When an electric soldering iron is not needed, it should be carefully placed on a suitable soldering iron holder to avoid damage to the soldering iron head due to collision.
Choose the appropriate soldering iron tip
Choosing the correct size and shape of the soldering iron head is very important. Choosing the right soldering iron head can make work more efficient and increase the durability of the soldering iron head. Choosing the wrong soldering iron head can affect the maximum efficiency of the soldering iron and reduce the welding quality as a result.
