Could cause a hard short, or nothing. Very unpredictable.

A hard short is absolutely the worst thing that could happen while vaping. This causes the battery to empty all of its power at one time, resulting in either the battery venting hot gas or going into thermal runaway (flames and/or explosion).

Read about "venting" and "thermal runaway" in this article:

Less dangerous in a regulated mod (electronic chip) than a purely mechanical mod. Processor should say "check atomizer", "no atomizer" or "atomizer short" and refuse to fire. In a mech, the battery will fire regardless if there is a short because there is no electronic chip to warn of a possible hard short.

Depends on a few things...

If a coil leg is truly just hanging in the air... that's an "open", there's no completed circuit for the electrical energy to flow. Unlimited (infinite) resistance.

If that leg happens to touch something inside the atomizer, depending on where it touches... that's a "short", an unintended circuit of virtually no resistance between the negative and positive terminals of the battery.

On an adjustable power "regulated" mod, the circuitry protections should notice both "out of range" resistances and refuse to fire or pass current to the atomizer.

On a non-regulated (no circuitry) "mechanical" mod... the "open" should do nothing. There's no circuit being closed... no current flow.

The "short" situation however, is problematic.
As Baditude's pic above shows... it can be very problematic. :eek:
No resistance, and no protections... the battery's output goes from zero to maximum immediately. They don't care for that much... at all.
Hence the reference "pipe bomb".


Always, always double check your connections... especially your coil tie-downs. ;)
(And watch what the coil itself may be accidentally touching. Same "short" result.)

Lol... got to rambling while watching the news. Sorry.

Is that melting down in top of black ring around center pin caused by so!???
Not sure what you're trying to show or ask here. Is the insulator between the center pin and the outer threads damaged? It looks intact. If there is damage, it could have been caused by an arc that happened when contact was almost made and the fire button was depressed.

Damage to that insulator could allow a short circuit. A regulated mod with working protection hardware would prevent anything bad from happening if the atty were used. On a mech, a short in the 510 assembly could end in fireworks.

Is this the same atomizer device asked about in the original post?
