I have a Snow Wolf and I bought it on impulse, the Ohms jump all over the place, is that the norm for these things, I first tried builds with Ni200, had a few that were O.K but, they were jumping all around so I threw a tank with NI200 coils on it to see if it was my builds and it still jumps. considering getting the Li, but I don't what the same problem. any input?
Nickel changes resistance radically as it heats up. The coil may be .15ohms at room temperature and .5ohms at 450F. That's how temperature control works, it reads the changes in resistance as the coil heats up and adjusts the wattage accordingly. That's also why you're supposed to lock the atomizer resistance in on the mod while both are at room temperature on the SX chips. The mod has to know the resistance at room temperature to read resistance changes properly.
In otherwords, it's not a problem at all, it's supposed to function like that.
