touching coils and non touching coils (ROOKIE vaper) :) NEED ADVICE

[Franciscus]

dear:
vapers


i saw some videos of mechanical atomizer setup such as taifun Gt and kayfun... both technique are different.. one the coils are touching each other and the other one is not touching each other...

my questions are..
1. what's the different from both technique....?
2. many people said, "you're not allowed to make the coils touching each other cause it will create shorts"... but when i see the touching coils technique.. i don't see any shorts?
3. is there any terms and conditions for both technique?

really need advice, before i blow up my atomizer! hahahahaaaa....

thanks

If your referring to rips double barrel shotgun build, it's a dual coil build to say it another way.

The other one I have seen is interlacing the coils and twisting the ends. Can't seem to find the video.

Nope make your wraps touch all you want. Just dont touch 1 coil to a 2nd coil in a dual coil setup. Even if you do nothing major will happen it will just misdirect the current and possibly shorten the resistance. Touching wraps is fine though, this is micro coiling. Reasons for this practice is mainly to squeeze as many wraps as you can into your atty and it seems to disburse the heat more evenly across the coil.

I'm relatively new to this coil building myself and by no means am I an expert, but I'll try to pass on what I have learned.

The spaced out coils you mentioned are called simple or spiral coils. The coils that are touching one another are called micro coils.

Tight (micro) coils allow for more consistent/even coil-on-wick temperature. Micro coils heat more quickly and will have smaller thermal zone temperature range. Coils lightly touching each other don't short out. Kanthal wire develops an oxidation layer, so as long as there is not significant pressure (depends upon amount of wire oxidation) between the touching coils, you are effectively insulated.

The issue with spiral coils is there invariably will be hot spots, or shorts, at some point in the wire when the coil is first wound. These hot spots have to be prodded or moved around to allow the heat to be more evenly consistant the length of the wire. You have to eliminate any shorts within the setup, or trouble can ensue. Popping of the coil being the least of the trouble.

A micro coil nearly eliminates the issue of these hot spots and potential shorts. In this sense micro coils are easier to make than spiral coils. Since a micro coil burns hotter than a spiral coil given the same length & gauge of wire, one can make a micro coil of higher resistance than a spiral coil of a lower resistance and get similar results. This negates the neccesity of making sub-ohm coils to achieve a certain vaping experience. There is a marginal increased risk involved with sub-ohm coils as you are using much higher wattage and pulling more amps from the battery, often in the grey zone of a battery's amp limits.

I hope this helps. If anyone can better explain these concepts, please feel free to correct me.

Baditude pretty much nailed it. Only i think the main difference is evolution of vapeing in the early days you were supposed to jump 3 times touch toes your big toe once and scratch your scalp between each wrap or else the mighty vapeing gods would strike down on you with the dreadful hotspot.
