I was surprised how a specialist makes a reliable electrical connection without using a soldering iron. In his hands it took less than a minute.
Background: From time to time I had to work with specialists in metering devices. Locksmiths - KIPia. For the removal and installation of metering devices for general house meters. At one of the objects, he connected broken wires.
I watched him work and was surprised how he easily tinned the wires with tin.
For those who do not know, this is done so that the compound does not oxidize from high humidity and thus the compound does not give problems in the future.
In order to tin the connection, you need a lighter, tin. And the connection itself.
The first step is to strip the wires.
We make a twist, tighter.
We take a bare twist, hold the solder over it. We bring the lighter.
We start simultaneous heating of the wire and solder. A drop of hot solder should fall on the wire and spread
It doesn't always work out well the first time. The main thing is not to overheat the wire.
The result is such a reliable connection.
On the left I used solder with rosin. From right without.
My electrical connections will now be much more reliable. It used to be too lazy to fiddle with a soldering iron. And now in 30 seconds you can tin the wires.
Do it, you will definitely succeed!
