The atomizer cartridge allows you to vaporize E-Cigarette liquids or liquid shisha. It uses the hot air coming from the torch to heat a fine stainless steel mesh to a given temperature. The liquid that is on the mesh is then turned to a vapor without burning. You should always start slowly with a low flame setting and work your way to your desired level. This cartridge allows the user to inhale a very large volume of vapor or steam if desired.
