Hello everyone.In this article I will tell you how to make a simple welding of wire twists based on a TS-180 power transformer and a carbon rod from a 1.5V finger battery.
To have a strong connection of two copper wires, their welding is used.To do this, you need a powerful transformer, in my case it is the TS-180, which can be found in old tube TVs.This transformer has two step-down windings of 6.3 Volts and a current of 4.7 A each.For welding, I use only one 6.3V winding.The greater the current at the output of the transformer, the larger the diameter of the wires can be welded.
But you can’t just connect two wires to the twist and weld, there must be a special contact that will give a spark.This contact-a carbon rod can be taken from a cheap salt battery.The larger the size of the battery, the larger the diameter of the carbon rod.
Before welding, the rod must be heated so that the paraffin evaporates from it, otherwise it will interfere during operation.
Now we take one wire coming from the transformer and connect it to the rod, we wrap the connection contact with pliers.The wires coming from the transformer must be stranded so as not to heat up and pass a large current.We connect the other wire from the transformer to the twist.We touch the edge of the carbon rod to the twist and weld.
The power of the transformer winding to which I connected is enough to weld two wires with a diameter of about 0.5 mm each, I did not check further.
