Thank you both for your advices!I'll try and find my sweet spot but if i feed the coil with 100w is there any chance it might burn?
Yes, firing it at 100watts there is a good chance you will "dry hit" and burn the cotton. That could even happen at 70 watts.
Start low and work your way up so that you can determine how high you can go without getting "dry hits". And make sure you are priming a new coil before you start using it.
Priming a Coil
All cotton coils have to be primed well with juice. If they are not primed well the cotton will burn. Once the cotton is burned the burned taste doesn't go away.
To prime the coil, drop 5-8 drops of juice right inside the coil (sometimes less/more depending on the size of the coil head), another drop of juice in all the holes on the side of the coil. I watch the cotton absorb the e-liquid and when it can't hold any more, I put the coil in the base.
- If Bottom Filling - Fill the tank and then screw the base back onto the tank.
- If Top Filling (some tanks are top filled) - Screw the tank on the base and then top fill it.
Once you put the tank on the battery give it several unpowered primer puffs. This will make sure the wick is fully saturated.
