Been using & very happy with the IGO-W dripping atomizer on top of my Provari Mini (Kanthal 32ga wire & 3mm braided silica wick) for the past 3 years. Wanted to try something new and bought an IGO-W7 & IGO-W14 dripping atomizers. This purchase proved how out of touch I've been with the vaping community & technology. The W14 is HUGE; haven't even tried to build it. Are there any mods with adjustable voltage that fit this thing's diameter? The W7 is a better fit on top of the Provari Mini but what ever build I try, I get a E1 code (short circuit). I get that code on the IGO-W7 even with a single coil build that works on the IGO-W. With no coil at all on it, I don't get a code so I figure its not internally short circuited. Do you think I got a bad unit or am I doing something wrong. Any help is well appreciated. Thanks.
