Question on a soldering iron with an "eternal" sting ...

Topics / Questions
Added 9 comments
I bought a soldering iron with an "eternal" sting for 100 watts. This sting, God forbid, clean with sandpaper and a file. He turned on the soldering iron, all the black sting, cleaned with soda, washed, turned on again, black again, the solder does not stick. Somehow I tinned the tip of the sting with acid in a day.

The question is, why invent this? Copper stings are flogged without problems, and if it is crap, it is shirted with a file and you solder further. Erased? Threw it and put a new one, it’s worth a penny! Or am I wrong in something?

In-in ... The plug was at least normal? Not "American"?

Are you sure that it is on 220V? Perhaps our Chinese friends again cheated on something? Try playing with a dimmer. scratch

According to the table, there should be 484 ohms, is it too much, my 600?

It is necessary either to dim the dimmer or diode.


Dmitry, so if you believe grandfather Zhore (He is Sema), then with 600 Ohms he should warm up less than with 484 declared.))))

Will the soldering iron also warm like 60 watts?
No, the powers will be shared in proportion to the resistances.

But what if you insert a 60-watt bulb in sequence? Will the soldering iron also warm like 60 watts?

turned off the light and got scared, the soldering iron tip shines red! Checked the resistance - 600 ohms. There are no ohms on the case.

To the question of eternity, did old Einstein say something there? And what for me something "eternal", if I myself am not immortal? scratch
