Hello, I realize that this is the new members forum but I thought I'd throw another question out there to see if anyone could help me. My set-up atm that is giving me this issue is : my (original Hex) Copper set up for 6v with two protected CR2 batteries and a 4ohm 306 atomizer. For some reason it's not working, I get no vapor at all. The same is true when I use my dual coil carts, I don't know if it's shorting the batteries out in the copper but both work fine on my 5v pass through. I use other high resistance (or high volt) 510 atomizers with the Copper and they work great. I can't think of what it is besides me being numb and combining two things that aren't meant to be combined. I would've asked Rick from Atmosusa but I feel like I've sent him a few too many emails lately.
