How to maintain an electric soldering iron?

Release Date:2016-08-16
Electric soldering iron is the main tool used in welding engineering, mainly used to melt tin. To know how to maintain an electric soldering iron, you should know how many parts it is composed of and how to use it.
Electric soldering irons can be roughly divided into four parts:
1. Soldering iron tip and its fixing screw;
2. Heater;
3. Handle;
4. Iron power cord and its fixing screws, plug;
Simply put, the method of using a soldering iron tip is to apply an appropriate amount of solder to the soldering iron tip, touch the solder joint, and wait for the solder on the solder joint to completely melt and submerge the component lead. Then, gently lift the soldering iron tip up along the pins of the component and leave the solder joint.
There are many things to pay attention to when maintaining an electric soldering iron:
Before welding, the following points should be noted:
1. Clean the soldering iron tip thoroughly and remove any remaining solder slag on it;
2. Control the moisture content of the compressed sponge at a suitable humidity level, without dripping or being too low, and avoid welding defects such as damage to the soldering iron tip or failure to solder;
3. Ensure the safe grounding of the soldering iron.
During the operation of an electric soldering iron, the following points should be noted:
1. Do not leave the soldering iron tip in a high-temperature area for a long time to prevent surface electroplating cracking of the soldering iron tip;
2. Do not apply pressure to the soldering iron tip or rub against the welding point, as this can easily damage the soldering iron tip;
After using the soldering iron, please note the following:
1. Clean the soldering iron tip thoroughly;
2. Add a new layer of tin to the soldering iron tip. Plays a protective role.
3. The soldering iron tip should be cleaned regularly and any foreign objects inside the sleeve should be removed.
For the use of electric soldering iron, there are some precautions below:
1. Do not use soldering iron tips for work other than welding;
2. Do not strike the soldering iron tip;
3. Do not modify the welding table without authorization;
4. Do not use an electric soldering iron with water on your hands;
5. Keep the environment ventilated and deal with harmful gases that may occur during the welding process. If possible, smoke purifiers can be used.
