Atty gets hot with ni200

[bob salter]

I seem to be having trouble with ni200 builds. I use a standard 7 wrap of .4 on 2.5mm former. Vapour production is low and the atty gets very hot. An Identical build in kanthal works flawlessly. What am I missing?

I had the same problem with ni200 and tried many builds mainly 7 wraps set to 340 volts on temp control. Since then I have gone back to kanthal wire and never looked back.

What resistance does that read as?

What have you got the temperature on the mod set to?

0.18 ohms and 410F.

Ok, Nickel is far more fiddly to build with than Kanthal, make sure nothing is touching the deck and the coils are spaced and even. See if that helps

You have a dodgy connection in there somewhere, 7 wraps of 0.4mm Ni200 with a 2.5mm internal diameter should be a coil of 0.06 - 0.07 ohms. So thats gonna mean your device is chucking more volts at the atty than it needs and generating heat wherever the poor connection is.
