suggested operating range for their OCC coils. You don't have to run at these ranges. It just give you some idea of how low/high you might go. As with any coil, prime them well (dropping juice directly into the coil head and into the coil holes) before you fill up your tank and assemble. Once you fill up the tank take a few primer puffs without pressing the fire button to make sure the coils are well primed with juice. Adjust your power or voltage low and slowly raise it up until you are satisfied. If you start to get a burnt taste (dry hit), back it down a notch or two.
Horizontal OCC Coils
0.5 Ω coils - 15 watts to 30 watts.
1.2 Ω coils - 12 watts to 25 watts.
