To dry burn a 510 atty, simply rinse with water, blow out both ends to get it somewhat dry, screw the atty into a battery, then energize the atty for at least 8 seconds while blowing into it. Repeat the last step about 4 more times. If all goes well, you will see an orange glow each time, and it will get brighter each time. Then, either direct drip or insert a cart. Works like a charm.
