Having Trouble with Ti builds

[Thejkaz]

My local shop sold me 28ga Ti wire and said I would need it to use the temp function on my EVIC VT. I have only gotten one build to work in my kanger RBA and it was 24 wraps around a 3/32 drill bit. I bought a a TOHB v2.5 and got a coil to work on that, 30 wraps pulled into a serial dual coil build comes in at .26 after a few pulls but it started at .14 but even at 600F temp control I don't get a warm vape or any flavor but I do get decent clouds. Am I doing something wrong?

Holy cow 30 wraps?

 

[ironman]

Check ur connections. I use 24ga with 9 wraps and get .25ohms

I tried the same coil on both decks with the same result.

I am thinking I just got a roll of crap wire

Very likely. 24 wraps is a lot of wire for a single coil. I don't even see how you can fit that in a deck. But post pics

I think I tossed the 24 wrap coil

Are you sure that's Ti and not Ni200? Check steam engine and you'll see what I mean.

 

[ironman]

I could be wrong but your right positive lead is not in the center post.

 

[ironman]

Try a single coil at 10 wraps.

 

[ironman]

Also if you build a dual coil try to even space it from the center post as well. Also looks like it's touching the center post.

I did a serial coil so it comes out of the top left ground around the center post without touching then connected the second coil to the positive center post.

Ah I see. I guess for now build a simple single macro build. 9-10 wraps

 

[Thejkaz]

I threw the box for the wire away and there is no info on the spool but I am sure that it is Ti. what gauge did you wrap the coil around?

 

[ironman]

2.5mm

 

[Thejkaz]

so about 7/64...All I have is drill bits right now.

 

[ironman]

Should work

 

[ironman]

Not mine, but you get the idea

 

[Thejkaz]

I have done that with this wire. The ohms came in around .08 if I remember correctly. One reason I bought the RDA was so I could try this wire out on a bigger deck.

 

[Thejkaz]

I will give it another go tomorrow. Thank you for your help.

Np, good luck let us know how it went

 

[Thejkaz]

Will do

 

[Thejkaz]

Haven't had a chance to build a new coil yet. Will let you know how it comes out tomorrow

Ok, sorry about the wait. I did 10 wraps on a 7/16 drill bit (just a tiny bit more that 2.5mm) and it is registering as .2 ohm. I guess I was trying micro coils and it just was not enough wire. Thank you for your help.

That sounds about right. Make sure they r spaced

I used 28 gauge nickel and three strands twisted with a drill with six three millimeter wraps and it seems to be working good so far

VAPE ON

 

[thorpemark1]

I was having loads of issues with weak vape, with titanium.. (was following a guide which recommended contact coils , and lightly pulsing them to work out hot spots )
This weekend I tried a clapton (Ti core with kanthal exterior ) and it seems to work awesome/ not impact resistance. dont know if the kanthal is stopping shorts , or creating slight spacing in the Ti .. but it seems to work great,.

 

[Thejkaz]

I am new to vaping and I dont really know the difference between kenthal and clapton coils but I did do a Kenthal/Ti/Kenthal twisted coil and I still have problems with the resistance. The last Ti build came out at .2 ohms but my box mod registered at .13and would only fire in TC mode. I guess Ti just isn't for me.
