Yep. Take a car for instance. Just because your speedometer says it will do 193 kmph (120 mph), doesn't mean that you need to go that fast to go to the corner store. From everything you've posted so far, I'm guessing that you already burned the wick in that coil you're using now so it's ruined. I would replace with a new coil, lower the power and, once it sits for a bit so the wick can get saturated, try turning up the power 2 - 4 watts at a time.
