New voltage limiter questions - 67 Dart 270

If you have done lots of these, I suspect you are doing them for other people.
If that is the case, I also suspect they are waiting till theirs get's fried.
I'm hoping to get ahead of that in this project car.
Well see when I open it up.
Any suggestion on soldering what I understand is Ni-chrome wire?
Tin it with silver solder?


I just found out about using bronze rod with TIG.

This sounds like a good solution to filling pin hole rust.
I plan to try it on another car I bought.
tig brazing with silicon-bronze filler, very cool

I serviced over 300 instruments during a 8 yr. period. Then I retired.
Solder wont stick to nickel. The wire is welded to the studs. The wire/weld hardens.
Movement of the wire ( it moves as the bi-metal beam moves ) would cause it to break. This is why you'll find a ball of cement like epoxy material on top of the weld. This is/was to relocate the movement.

Hum.
Glue.
We'll there's an option.

Attaching nichrome wire to copper

"Why not just twist the wires and use epoxy putty?? I'd have to check the temp ratings and see what happens over long use of heat on the epoxy putty. (is muffler stuff good?) Also some is more resistive than others."
