Zivipf NiFe30, NiFe48. Going in & out of Temp & Watts mode

[S_wilson]

As posted earlier I am new to escribe. I have been trying to use the 2 above wires for the last few days. I am using the CSV files from SE for Nifethal 52 & Nifethal 70. When I use either of these wires everything starts out ok working under their temp profile. But after a few minutes the resistance rises up mod goes into watts mode. Then maybe later temp starts working again. This switch usually happens when I put mod down for a few minutes. So far I have checked 510 on mod, used 3 different atties with varying set ups of wire from single to dual coils & made sure my profiles had correct wire type & CSV in them. This happens with them all. I am using contact coils that have been dry burned & maybe that is the problem. Since I am new to the dna75 I wasn't sure if there is something else I'm missing. I have read that you don't have to lock resistance on the 75 or 200 so I haven't been. Not even sure if that is possible unless u have it connected to escribe. BTW I have used ni200 & it works as should in the Ni profile of course with these I use spaced coils.

you can lock the resistance from the mod. lock the mod (5x or however many you have it set), then hold fire and +. just be sure to lock in a COLD base resistance. i use this feature sometimes on less then great atty's i use for TC.

Have you tried using slightly spaced coils? Some wires do better that way- I personally haven't used those wires but it's something to consider.

Switched to spaced coils with NiFe30 & NiFe48. Resistance is now stable & TC works as it should.

What TCR value are you set for Nife48 wire? 

[S_wilson]

I used the TFR curve CSV file from steam engine for Nifethal 52(alloy 52) But 0.00405 is the TCR value for zivipf. Since I started this post I have used niFe48 a good bit. For me spacing made a huge difference. The more spaced the better for me.

I use the stealth vape nife30 and swear by it,, it has its own tcr in steam engin, my coils are untidy spaced and gaps between coil hoops probly greater than the thickness of the wire, some coil hoops might touch a little, but i never have any problems, the trick i find is make sure the coil is firm fitted, cant move or buckle under heat, not touching the sides of chimneys and lifted off flat bed build decks (so lead leggs arnt dragging making contact) and also on a new coil start with low watts and heat and slowly build up to your desiered temp, i never pre burn these coils.
