Replacing Soldering Iron Tip: Guide for Beginners Using Cheap Models

I know it's not the best, but I'm just starting my adventure with electronics and at the beginning I preferred to buy something cheap.

For the first few days everything was ok, but after some time the tin started to fall off the soldering iron tip - it doesn't stick at all.

I read on this forum that it is necessary to replace the tip with a new one (preferably with a copper cable) - how to go about replacing it?

Regards

Read a bit about soldering:

Try to touch the hot tip with salmiak (such a white stone that helps in soldering) and then pick up a bit of tin. You can also try to lightly grind the top layer of this tip, maybe it will help.

yogi009 - electronics soldering and salmiak!!! don't make fun of your friend. Buy rosin and whiten it elegantly, and at the beginning solder a 1cmX1cm cube. As you solder, you will already know everything about soldering.
Also read what my friend wrote above.
Good luck.

Use tin already with rosin, preferably 'ones'. In addition, buy yourself a rosin separately - it is very useful. I would suggest you drill holes on the printed circuit board and practice soldering some old stuff on it.
Also, clean the tip from time to time. He can't be trusted and scorched. I had the same problem with practically the same soldering iron (mine has 30W and 130W operating ranges). After soldering a few boards and reading a few PDFs, the practice comes by itself. I have no problems with it anymore.

Secondly, it is better to add tin to the place heated with the tip where the solder is to remain, and not to transfer it on the tip.

If you complain about the tip in this soldering iron, actually replace it with a copper one. You unscrew two screws and the old one falls out. And you make a new copper one to its size. The most important thing here is the diameter, so that it fits quite tightly into the hole and receives as much heat as possible from the heater.
The set includes tin, rosin, some paste, and a steel wool or special sponge cleaner. And practice...
Although a classic transformer soldering iron would be better for you, and not some attached heater wonder...

Dreamer93 · Answer

I wouldn't complain because I solder this one 100x better than the transformer one. But that's personal feeling.

I will attach to this topic I have lutola 6A soldering irons.

I finally replaced the tip with a new one and the tin seems to hold it now but why is this happening?
I used it maybe 2 times, did I burn it?
How not to make the same mistake again?

snopa · Answer

In the video you can see that there is a tarnish on the tip, clean it and it should be ok.

kamil195 · Answer

Ok, I'll check, and by the way, does anyone have an interesting idea for such a Sunday lutmaster how to scrape it inexpensively? enough sandpaper? Does it have to be some kind of cellulose sponge?

ciasteczkowypotwor · Answer

kamil195, take a 1.5mm2 copper wire and make a new tip, dip it in rosin during the first heating, and then whiten the end with tin.
