Can't get 28 gauge to go above .4 ohms

[Jengelh6471]

Hi All,

I have a weird situation. Been vaping for a while now. Usually using 30 gauge a1. I've done a lot of building for my Protank 2 and my Igo-l. I have no problem getting the ohms where I want. Now I wanted to try 28 gauge kanthal and get around 1.0 - 1.2 ohms on my Igo-L. No matter what I do it comes up on the multimeter at .4 ohms. I have followed many videos and tutorials to see if I'm doing something wrong. It doesn't seem to matter what I do it comes up the same. If I switch back to 30 gauge I can wrap 1.5-1.7 ohm coils no problem. Even make then in the 2.0 range with ease.

Here's and example of a couple things I've done.

Wrap 10 times on a 1/16 bit. Get .4 ohms
Wrap 10 times on a 1/8 bit. Get .4 ohms

Tried many variations bit sizes, number of wraps, but still get the same .4 ohms. Now if I switch back to 30 gauge, again no problems.
I've used my multimeter and my svd to check the ohms. I know the svd is still supposed to read low ohms, just not fire it and it comes up with 0.0 ohms.

This is boggling me and driving me crazy because I'm doing no different than anyone else. Could it possibly be the Igo-l?

Any help would be much appreciated.

Thanks

Those diameters are nearly the same either try more wraps or a much bigger diameter another way to go about it is try with a different gauge wire.

Any chance your 28 gauge wire is NR wire by mistake?

Spool out a length of wire. Put one multimeter probe on one end, and slide the other probe along the wire. If you don't see the resistance going up, you've got the wrong stuff.

On the other hand, if the resistance does go up, find the length that matches your target resistance. Then just use that amount of wire to wrap your coil (leaving extra for the legs).

10 wraps of .28 around a piece of .28 is over .4 ohms. Maybe n/r or maybe your dmm is on the fritz.

sounds like you don't have 28 kanthal.... possibly plain wire... check about 1 foot of it with a ohm meter, should be around 2.5-3.2 ohms ( just guessing)

Just FYI the SVD will fire subohm, I run .8 in my IGO on the SVD all the time , As long as you remain under the 5 amp limit it'll fire,if you're using the multimeter properly , you've got some mislabeled wire , probably NR .

That IS bizarre. I mean it would be a no brainer to blame the meter but your svd can't pick it up either....

Regular wire shouldn't give you .4 ohms either. That's the wierdest part, there is SOME resistance. If there is some resistance to the wire your using then more of it should obviously give you more resistance...

Unless it's a cheapie meter that picks up the resistance of it's own leads. What do u read if you touch them together? .4?

Have you tried it on a mech yet? I mean, DONT, but...that's what I would do lol.

 

[Brian Roche]

One day I got to a call and realized I had forgotten my toolbag. Stopped at radio shack and bought the cheapest meter they had.

Happens that I've got that meter on my truck still. I just touched the leads together....It reads three tenths of an ohm. That wire you have is n.r. dude.

Radio shack meter in the trash at mcdonalds now....

JMarca- I have tried all different diameters. 1/16 and 1/8 is quite a difference in size.


TWGbonehead- I just tried that and the resistance does go up. But if I was to try that and cut it at where the target ohms is, I would have to wrap it about 60 times.

The multimeter is innova. I checked other things. Seems to be accurate.

I'm getting .2 with digital caliper.

Just as a note. When I slide the lead along the wire, just to get to 1ohm it was at around 1 1/2 ft. to almost 2 ft. in length. Does that sound normal? Doesn't to me but I'm just asking.

Brian Roche- To late I had already done that. I took it outside and just pulsed it and it fried the coil immediately.

So, I wrapped up a micro with 30g around 1/16 bit 10 times and I got 1.7 ohms. This is all very weird.

What you have isn't nichrome or kanthal. (Or isn't 28ga) 28ga should be about .32mm dia. Should be about 5.2 ohms/foot.

 

[Jengelh6471]

I got it.. The label was scratched off partially. I compared it to the label on the site. It is Nickel 28g awg non resistant wire. They did give me the wrong stuff. Grrr. Wonder if I can get my money back because I used half of it wrapping 30 coils trying to figure this out. The label even though it was scratched up looked a bit different than my 30g spool label.

Thanks everyone for helping. I wouldn't have researched that if you guys didn't give me the ideas.

Same here. Can't even get my multimeter to read anything I build correctly. Especially trying for dual coils. I'm using a Nimbus clone and a Phoenix V6. Both end up firing but I'm not sure they are safe to vape and on what battery because I can't get a decent reading.

 

[Memorandom7]

Just saw your resolution. I'll post somewhere else lol

 

[Jengelh6471]

LOL! Yeah I went back and the guy checked and apparently they were mixed in their shipment because they dont usually carry non resistant wire. Got the right stuff. At least now I know im not going crazy. Ha! Do you think that is whats wrong with yours Memorandom7?

No. I just was trying to get around 1.0 Ohms with 28GA in a dual coil build. I just need thinner wire. Doesn't work out mathematically the way I thought. 30GA got me to where I want to be for now. Glad you sussed that all out!
