How to connect an old soldering iron without grounding to a grounded outlet?

Question

Do it yourself

There is an old Soviet soldering iron (working). He has a two-core wire, i.e. without land, I understand. The problem is that its plug cannot be inserted into new sockets and carriers. Therefore, I took a regular computer power plug and decided to screw it in instead of the old soldering iron plug. But bad luck, the cable is three-core, in which case where to put the ground wire? can it be connected to zero for example? Or not connect at all?

Answer 1

can it be connected to zero for example?

And then flip the fork. Here's some laughter...

Answer 2

You don’t have to do this: you will have a twist of wires, which can leak and the phase will fall on the carcass. Buy a normal collapsible fork and put it in place of the old one.

Answer 3

The first option is to saw off what prevents the plug from being inserted.
Second - buy a plug with grounding, and connect the grounding to the body / soldering iron tip - less likely to kill the electronics, just be sure to check if there is grounding in the outlet, otherwise you will get a voltage divider on the capacitors and 120+ volts on the tip, in not the worst case.

Answer 4

Do not connect the yellow-green earth at all, but if such questions arise, it is better to contact a specialist.

Answer 5

Connect it to the body of the soldering iron. Usually the tip itself is heated by the heating elements and has no electrical contact with the "power cables".
