I'm new to vaping and I bought a raptor t6 mod paired with a fuel rda. The mod has copper connections and I'm using it with a Samsung 25r. I have dual coils on a .50g kanthal on my rda. I've noticed that sometimes I can pull huge clouds from it and after a few pulls the clouds seem to get thinner and thinner with every pull. Can someone please explain this to me. What am I doing wrong and what should I do to keep the clouds thick, thanks!
