There are many possibilities, but it is better to make a colleague aware than to complain: The primary winding can be checked with an ohmmeter, and crossing the street on lanes can also be deadly

Justyniunia · Answer

The thickness of the wire at the bottom of the photo speaks for the secondary winding 6, 7, 8, 9. Don't be surprised, because the primary one can be wound under the secondary one.

Does it have a symbol?

Hello
For such experiences, I would buy a transformer soldering iron. I would take out the transformer and wind the secondary winding if needed. This transformer has flooded windings and there is no room for additional winding.

Let me put it this way, the pity of our domestic unitra-brand transformer will be lost to such crap.
How will it apply, will you burn the wires like in a (stupid) movie?
Waste of time.
If you care about high current and low voltage, use the transformer soldering transformer.
It will release about 200A at 0V5.

I'm afraid it is a transformer as I write "Justyniunia". I have a second transformer of this construction, but it seems like it would be the opposite, i.e. the primary winding is first and the secondary winding below it (photos). I was wrong to remove the primary winding because you have to remove the secondary one. As the gentlemen from the movies say:

There are no symbols except numbers.

@ nowy.zielony.pczątku Think if it doesn't hurt you! Where do you see the similarity ?! Trafo from the last video pasted is a microwave photo. I will not write you anything about it because there are tensions of a few KV, so it is deadly.

vodiczka · Answer

There are no more kV in this video. What difference does it make if you are rewinding 230V / 230V or 230V / 2400V since in both cases you are removing the secondary winding?

I wrote... As shown in the pictures. I feel sorry for the transformer soldering iron. These transformers were to be dismantled anyway. Okay, I'll try first with a small transformer (see what the results will be).

Rezystor240 · Answer

It is possible that before rewinding (in this case, rather a modification), he will connect the transformer to the network to check if it works. I will not say what may happen next. It is a pity to disassemble such a transformer, after all, it is manufactured in Poland, and this can be experienced less and less. You don't have to disassemble the transformer soldering iron, you just need to unbend the flat bars and connect the wires, you will always restore them to their original condition. This transformer (from the photo) does not even have 30W, so at most you can light a bulb with a piece of rod.

Eventually, I gave up connecting the unitry transformer. I made a welding machine from a transformer from a microwave.
