Is it possible to have a dangerous pickup on a twisted pair cable and a TV cable from welding?

Question

Computer networks

The house is reinforced concrete, the Internet provider has optics in the basement and a whirlwind on the floors, so I was never particularly interested in the problem of pickups from thunderstorms, but I heard that a lightning strike can induce voltage in cables and disable equipment, but then I accidentally left the apartment and saw how neighbors put an iron door, their wires hang down the door and the welder welds the door 3-5 centimeters from the bundle of wires, wondered what kind of electromagnetic voltage in this place is probably induced on the wires. It is clear that if they burn something, the port on the switch in the basement or their pieces of iron, but after all, the arc is probably comparable in terms of radiation power to lightning if it is cooked in the very vicinity, and after all, lightning also passes through the switch to subscribers, I heard how to protect yourself from such situations , equipment at home is expensive, and now it has become fashionable to install doors, before the windows were changed (a neighbor appeared and they need it), now all the windows have been put on the doors and they have moved. Or is welding not so dangerous in this case and the danger is only from lightning?

Answer 1

No. Welding and lightning are different things and their power (as well as voltage) is completely different.

Answer 2

Dangerous pickup can only be if the power cable of the welding machine runs for a long distance next to the twisted pair or coaxial cable. If they simply boil next to the cable, then there is a chance to burn it with a drop of molten metal.

Answer 3

And if, for example, when mounting the door, they interrupt the twisted pair and one of the wires touches the door profile and they begin to cook it, what can be theoretical in this case? Or since theoretically argue what will happen if you put an arc into a twisted pair.

Answer 4

No, not dangerous. In general, if you are interested in argon welding, you can read all the information on this site . He specializes in welding.
