What should I do if the soldering iron tip is overheated? What are the solutions?
After the soldering iron is energized, the temperature is as high as 250 degrees Celsius. When not in use, it should be placed on the soldering iron stand, but when it is not used for a long time, the power should be cut off to prevent the high temperature from "burning" the soldering iron tip (oxidized). It is necessary to prevent the electric soldering iron from scalding other components, especially the power cord. If the insulation layer is burned by the soldering iron without paying attention, it will easily lead to safety accidents. As a result, the tip of the soldering iron was burned black and burned off.
Soldering iron tip overheating solution:
1. Cut off the power supply for cooling
2. Insert the temporarily unused soldering iron into the metal soldering iron stand, and use the heat transfer and large-area heat dissipation to cool the soldering iron. When the soldering iron is taken out from the soldering iron stand, the soldering iron will quickly rise to a solderable temperature without the heat dissipation of the soldering iron stand.
3. Connect a group in series on the power cord of the soldering iron, a parallel circuit consisting of a diode 1N4007 and a switch. When the soldering iron is not used for a long time, you can turn off the switch, so that the soldering iron can only get half-cycle power frequency power supply, and the temperature will not overheat; when the soldering iron is in use, close the switch, so that the soldering iron will receive normal power supply and the temperature will rise .
4. Ordinary electric soldering irons can be made into a simple electric soldering iron stand. A micro switch is installed under the soldering iron stand. After the soldering iron is put on, a rectifier diode is connected in series to reduce the temperature. The soldering iron burned.
5. Natural cooling is better for the soldering iron tip, and forced cooling with cold water will shorten the service life of the soldering iron tip.
If the soldering iron is energized for a long time, the temperature will be too high and the service life will be shortened, and the soldering iron tip is easy to "burn out" and make it difficult to "eat tin". The energy consumption of the constant temperature soldering station is relatively low, because when the adjusted temperature is reached, the heating is not carried out, and the corresponding energy consumption is low, that is to say, the same welding effect, the soldering station consumes less electricity. You can choose a constant temperature soldering station to solve the problem of overheating the soldering iron tip.
