Electric soldering iron is insoluble and does not stick to tin
Electric soldering iron is a necessary tool for electronic enthusiasts and practitioners. New electric soldering irons have a protective layer on their heads, which can protect them from oxidation. At this time, it is easy to solder on the electric soldering iron, but improper operation such as continuous heating, use of acidic soldering flux, and failure to add soldering when not in use can lead to premature oxidation of the soldering iron tip, resulting in the inability to solder.
Some ordinary electric soldering irons, due to their lack of constant temperature and temperature adjustment functions, and their low price, do not use copper or alloy soldering iron tips. After being powered on, the electric soldering iron is in a continuous heating state, and the soldering iron tip is prone to oxidation. Some electric soldering irons may even experience the phenomenon of the soldering iron tip burning red.
Solution:
It is necessary to use a file or sandpaper to polish the soldering iron head, remove the oxide layer on the surface of the soldering iron head, then enter the rosin, rotate back and forth a few times, and add solder. If the soldering iron head still cannot be soldered properly after this method, a new soldering iron head needs to be replaced, and a suitable soldering iron head should be selected based on the soldering iron model and power.
Like some constant temperature electric soldering irons, such as the commonly used 936 soldering station. Due to its temperature regulation and constant temperature function, the soldering iron head is made of alloy soldering iron, which is not easily oxidized and can work stably at the set temperature. And this type of electric soldering iron not only heats up very quickly, but some also have the function of not shutting down automatically for a long time, greatly reducing the oxidation of the soldering iron head. Therefore, it is recommended to use this type of soldering iron as it is more convenient.
Precautions for using soldering iron:
When the soldering iron is not in use, it must be promptly powered off or soldered onto the soldering iron head to prevent oxidation. Do not use acidic flux as it can easily cause oxidation of the soldering iron tip. A flux mixed with rosin and alcohol can be used for auxiliary welding during welding. In terms of solder selection, it is necessary to choose some good solder.
