Temp control setting for different wires

[combatwombat]

I make claptons with a 430ss 28 awg core and wrap with a 316l ss outer wire. Should I set the tcr in escribe to 430 or 316l? Thanks!

Always set TCR according to the core wire.

aonoukraine, I am curious, why do you say according to the core wire?

I may be extremely tired from coding, but I believe you'd do a custom curve in Steam Engine with the two wires considered to be electrically in parallel.

Not trying to steal the thread from OP but I have to ask. Would this work with a Kanthal core and ni200 wrap, making a custom curve or is the two different materials not something the board would deal with.

Yes, you're tired:-) The wire you use as wrap can not significantly affect TCR or even basic resistance because of it's length is approx 15x greater than core wire. Check on steam engine - the TFR curve stays the same when you switch from single ss wire to ss/kanthal clapton. The main rule for claptons is to use temp sensitive wire as core, wrapping doesn't matter.

Thanks. I forgot about the wire wizard on steam engine.
