How to protect the soldering tip of your electric soldering iron
1. Before using the soldering iron, tin the soldering iron tip.
2. Use sandpaper or a file to polish the copper soldering iron tip. After connecting the power supply for a few minutes, the color of the soldering iron tip will change, indicating that the soldering iron is hot. When the temperature of the soldering iron tip rises to the melting point of the solder, use it to dip the rosin solder wire. The surface of the soldering iron tip will be dipped in a layer of bright tin, and the soldering iron tip is ready for use.
3. Note: The soldering iron tip that is not dipped in tin will not be tinned during soldering and cannot be soldered.
4. The soldering iron tip should be kept clean
Be sure to keep the soldering iron tip clean. A dirty soldering iron tip will oxidize quickly and cannot be tinned. Over time, it will cause corroded pits on the soldering iron tip, making the welding work more difficult.
If the soldering iron is left in the soldering state for a long time and the temperature is too high, it will cause the soldering iron head to "burn out". When not welding, the power of the soldering iron must be turned off immediately.
The oxides and carbides derived from the residual flux on the soldering iron tip will damage the soldering iron tip and reduce its thermal conductivity.
Therefore, cleaning the soldering iron tip frequently with a temperature-resistant wet sponge can prevent damage to the soldering iron tip. After each use, the soldering iron tip needs to be wiped clean and dipped in a layer of tin to protect the soldering tip.
Safety precautions when using a soldering iron
The soldering iron is a hand-held tool, so you must pay attention to safety when using it.
For a newly used soldering iron, the insulation resistance between the power cord and the metal shell of the soldering iron must be checked before use.
In order to save costs during production, some manufacturers use plastic wires instead of fancy wires for the power cords of their soldering irons, which poses a huge safety risk. It is recommended to replace it with floral thread. The fabric with floral thread is not easy to be burned or damaged.
The electric soldering iron needs to be placed on the soldering iron stand and cannot be placed randomly. Pay attention to the wire not touching the soldering iron tip to avoid burning items and causing a fire.
Keep the soldering iron dry and do not knock the soldering iron during use to avoid damage.
Regularly check whether the power cord of the soldering iron is damaged, whether the terminals in the soldering iron handle are loose, etc., and whether the insulation resistance is qualified.
