TC beyond Ni200: Nickel Purity, Dicodes; Ti, SS, Resistherm NiFe30; Coefficient of Resistance

[jhelliwell]

My zivipf NiFe48 26AWG has arrived. Steam engine suggests a TCR of 0.004036, but I read #GeorgeS post above suggesting a TCR of 47. This doesn't seem to make much sense, unless this is a NP offset. What chipset are you using GeorgeS ? I will be using either my DNA200 or SX350J chipset depending on whichever mod has the most charge remaining when I get round to coiling it

You guys who have had success with NiFe48 can you give me an idea of a single coil for my STM that will work for a while. I tried 6wrap 2.5mm with not much success. Worked good at first but just sort of fizzled out low vapor and flavor now after only one day. Going to try something else before I give it up any ideas. Wheres the Bloke when you need him he thought this was the greatest thing since sliced bread but it's not working for me so far.

Call me TheBloke Jr., if you like. [emoji41]

The closest atty I have to a STM is my Lemo 2.

I had the same coil in it for a week outstanding flavor and a ton of vapor.

Searching a little further, I rewicked yesterday because I put too much heat in the coil when dry-burning.

I suggest a 6-wrap spaced, dry-burned, and then compress just as you would do with Kanthal A1.

@2legsshrt - It sounds more like a wicking issue then coil "low vapor" What version STM do you have?
Does the barrel have the holes? & screw attachment? What Gauge are you building with & or do you have on hand?
I think "properly prepped" NiFe 52 is the best TC wire hands down it's all I'm using even on mech's. Right now I'm building a 3 strand parallel to interchange btwn a series box & dna 200

 

[2legsshrt]

Still at 2.5? I thought this stuff was supposed to be easier then Ti doesn't sound like it to me. With Kanthal I wrapped a contact coil on coilmaster dry burned strummed wicked and vaped.

 

[2legsshrt]

Oh I'm using 26awg

I suggest you try it in Kanthal mode to see how it vapes then proceed from there. I look at the recommended values as just that, a reference point if you will. I generally tweak it a bit then do a dry cotton burn test to see just how much protection it offers. It's vape right first, protection 2nd. Just my opinion though.
There should be no problem getting 30 - 35 watts from that atty/build.

The Apollo Reliant uses a custom SXK chipset. The TCR that it uses is going to be MUCH different than what a YiHi 350J or DNA200 should use.

While published numbers are great starting points, I would not of known what TCR the Reliant actually needed without testing it myself.

I use the standard STM with the standard RBA not with the holes in the side. Has worked really well for me with nickel and Ti.

Yikes not sure about that. I haven't used power like that even with a kanthal build at .5ohms. I dry burned this puppy at 12w. For me the whole idea of TC is to get a good vape and a constant vape. I haven't used a non regulated mod for well since the Provari first came out. Got one of the first ones and have never looked back. I guess what I was looking for with this stuff was a quality consistent vape with excellent flavor like Ti gives with the ease of using Kanthal. Maybe I was hoping for too much. I guess I was hoping to be able to wrap a microcoil on my coilmaster placing it dry burning it strumming till it glowed from the inside out then change back to TC mode with the TCR adjustment recommended and getting a vape like with Ti and being able to clean it with a dry burn.

 

[2legsshrt]

The miracle wire. I don't think at least so far this is it. Maybe I haven't given it a good enough chance but I'm going to the VA for a while, they like to do the Catscans on Saturday. Taking Ti attys with me will work some more on this when I get home. I hope the cat is in a good mood.

Have a zivipf order all teed up but can't figure out how to pay. I registered, have an account, my order all teed up, went to paypal but order didn't transfer in....received an email for my order....didn't pay for it....arrgh

i couldn't bring my self to ditch the twisted nife build in my sapor. so i just created a profile with 1 watt preheat, no preheat pretty much. im guessing with so much coil mass, thats why the temp isnt as smooth as a plane jane single coil nife. also this is after a few pulls and the wicking wasn't as wet, but at least now im not drawing crazy amps during preheat. with my luck, the head gasket would blow or the dna's timing belt would snap throwing up a 'warranty service'.

yup! I have an 'old' sxk shark clone and settled on 40 or so for Ti so Im noit surprised you are up at 47 for NiFe48!

Hmm mine went right through. Now you don't know whether they got it or not.

 

[2legsshrt]

Come to think of it when I placed my order Paypals website was having trouble and I got an email after a couple of hours asking if I wanted to send somebody the money. They used the name Thomas Schmoll

Well the Reliant is a bit of an "odd duck"

• TCR adjustment for < $100
• No fixed wire settings built in - only a recommendation in the manual for Ni wire
• Forget the "actual" TCR of the wire, the Reliant needs to use a different number

while my two 350J devices have SS430 builds I'll leave the Reliant with the NiFe48. I'll admit that after +40yrs of analogs I can't tell the flavor difference between different wire types. Since I usually use %100VG (and way below the boiling point for VG vaping temperatures) I can however tell the difference in vapor production.

Personally the differences I've noticed tend to disappear once I get the TCR set right. When my 3rd TSV4 shows up (its in SanFran right now) I'll toss a NiFe48 on it and see how it compares to the TSV4's with SS430 builds.

While the NiFe48 seems to be easier to work with, I do like the high resistance of the SS430. Just about all but a few of my SS430 builds I can fire on my old 15W VV mods as long as the coil is >=1.0 ohms.

Here's kind of what I'm talking about. I'm pretty much vaping watts with over temp protection. The first drag would have been about the same temp on or off and the second one not much different either. I'm not suggesting that you leave temp mode off, just off long enough to see what the difference might be. Here's my live view:

I'm getting a stellar vape with this.

But with this one the vape is quite poor, all things are the same except the TCR curve.

Absolutely. So the SXK 'nickel purity' chip appeared in april or so (maybe before - seems like a long time ago..) and @TheBloke noticed pretty quickly that NP was, in essence, an approximation to the wire TCR value! My VS clone cost about $45 I think. It still works and I still screw around with the NP setting with new wires!
