Atlantis v2 coil rebuild.

[Jerry0527]

Hello all I am new to this site and thought I'd come for help here.

I have my Ohm tester and both 26awg and 24awg kanthal wire. I have a coil building kit and have tried many different variations on how many wraps, vertical,, horizontal ect. Every coil I have tried out always reads between 1.2-.90ohm. I am trying to reach between .60 - .50 ohm. I am at a lost and probably built around 30 last night and for some reason never got it. Once I was able to receive the correct ohms but once wrapped and put away it went back up to 1.2ohm. I have tried different testers thinking my first one was not reading correctly and this is not the issue. Any thoughts?

I've rebuilt these. Its fairly easy depending on the wire and spacing your using.

I had my best luck with Ni200, lots of wraps 32-28AWG, bring both leads down to the bottom on different sides of the coil and capture the outside lead with the insulator and the inside lead with the center pin.

It is fairly easy to 'over wick' and create coils that are two long. The coil needs to be longer than it is round (stability in tube) and any overwrap of cotton very far on the ends of the coil will expand and shut off the air flow. To little cotton around the coil and it will 'float', to much cotton and the coil will be sunk in the cotton and require tons of power to do anything.

There are a number of youtube videos on rebuilding them - I surely can't add to what is already said and done other than I was unable to rebuild an Atlantis atomizer with SS430, Ni200 and Ti1 work fine, could NOT get SS to work.

I believe 26g Kanthal should be around 3.24Ω/ft. So divide 3.24/12 to get your ohms per inch and you get .27Ω/inch. So to hit about .6 you'd need 2"
The Atlantis coils are spot welded to non resistance wire for the posi & neg leads. The wire that actually heats up is only about 3-4 wraps in the middle of the coil. Which I measured out to be 2" of Kanthal. What you could do is wrap a 26g spaced parallel coil, so the resistance lowers by half. Then use a 3.5mm bit size and do about 4" of spaced wraps (not included the +/- leads). Should ohm out where you want it. Hope this helps a bit.
