Thank you for taking the time to respond. I'm still getting the same issue. I don't get any vape (or voltage) till i take into the 500 degrees area. It seems to work well on nickle setting but i don't thing it is actually temp protecting it. I am off work tomorrow & will have time to experiment better. especially if i burn my coil. i will make a new thread tomorrow with my results. My apologies if I nudged thread into a self serving question everyone.
