As Kaisen said, set the voltage on the Twist down to the lowest setting (3.2v ?). That may not make much vapor at that setting, but that will be the setting for the coolest vapor. Adjust the voltage higher in increments to gain more vapor without getting the burnt taste.
Generally the higher resistance coils (2.5 ohm) on the Kanger would make the cooler vapor; lower resistance coils (1.8 ohm) would be warmer.
If this is your first e-cig, understand that the vapor may at first seem too warm to your liking. Just like with cigarettes, it may take your body time to adjust from smoke to vapor. The good news is you don't have to inhale vapor into your lungs to get the nicotine in it. Mouth inhales will absorb the nicotine. As you can, gradually try to do little lung inhalations, and exhale through your mouth and nose.
It's also possible that you got a bad clearomizer. If you purchased this from a local vape shop, make a return visit and let the sales staff determine if the problem is with the clearomizer.
