I'm wondering what people think might be causing atomizers' resistance to change over time. It seems everyone has noticed usage increases the resistance of the attys. Any ideas what might cause this?
Why do atomizers' resistance change?

Since resistance increases with heat, I would imagine that any build up on the coil itself (or flooding during use) would be enough to increase it and affect the output of the atomizer.

My personal experience is that the net resistance changes for one of two reasons:
1) A degradation of the "weld" between the internal wiring and the ends of the nichrome coil.
2) Actual degradation of the nichrome coil itself.
#2 is more prevalent. As the PG or VG "vaporizes away", there is slight oxidation/erosion of the surface of the nichrome coil. The wire continues to get thinner and thinner... slowly raising the resistance. And then, at some point, it simply blows "open".

Why do some 510 atties have a harder draw than others? the one with easier draw does much better, I wish I knew why!!!
Ohms
. The little upside down horseshoe with feet symbol. One probe to the center hole and one probe to the threads. I think they're 2.2 when new.
First off saying '510' these days doesn't mean much. Which 510 do you own? Lots of semi-clones out there based on the original Joye 510 whose atties come in at about 2.2-2.3 ohms when new. The clones are always higher.
My new Joye atties come in at about 2.2 ohms. On the same meter a new SLB/DSE 510 atty comes in at about 3 ohms. The Joye I'm using now is at 1.7 ohms (about 6 weeks old). But don't expect a cheap meter to give correct readings, though it should be useful for comparisons.

Well, good to know I'm not crazy. I was thinking the extra resistance was just me having my own little issue...
I prefer it. The lower ohm Joyes produce a much better throat hit (if that is important). The SLB/DSE 510 (it has a washer inside) at about 3 ohms pulls less current. It produces decent vapor but doesn't 'hit' like a Joye 510, it's more like a DSE 901. It also appears more cheaply built with a thinner casing that does not hold Joye 510 tips very well. The first one I had did not last long (could have been a fluke), I just picked up another to see how it lasts. But it seems that lately SLB/DSE products have not been very reliable.
Keep in mind the original high praise and recommendations for the '510' were for the Joye 510 (or those renamed/custom branded Joye 510s). Not these cheaper semi-clones that came later.
Seeing as I can get two authentic Joye 510 atties from LiteCigUSA for $15.90 shipped I see no reason to use the less impressive semi-clone atties.
Thanks WillieB, I didn't know that. I will now make sure I buy the Joye's and see if thats better.
Lots of good info floating around in here. To add my 2 cents, the higher resistance atties (510 clones) are probably better at 5-6v. You should get less of a burning taste.
Scott B - Since you seem to be proficient with an ohm meter, a question: I have had a couple of m4xx attys quit working but the resistance across the heater coil (atty center cond. to case/threads) measures pn the order of around 220-230 ohms. Is an atty like this salvagable by, say maybe anH2O2 burn or am I merely seeing some other path to gnd/common and the coil has truly blown open?
I'm not Scott B, but since new atomizers range from 2-5 ohms, not 220-230 ohms, yours are toast. Nothing you can do short of replacing the coil will bring them back.
why is my atty not working? It is not the battery because I have a back up 1. The battery just blinks when I hit on it. It is about 3 wks. old.
It is working again? It stopped Sun. it is now Wed. These things take a lot of maintenance don't they. it is 3/10 & I haven't smoked a cig since 2/5 & don't mind the upkeep process because it is worth it I just don't know if I'm doing it properly. I will say this Eric @ save a smoker here in AL where I got some of my products has been very, very helpful & always answers the phone & emails.
They don't need a lot of maintenance - occasional blow-out, rarely a hot shower, keeps them running for weeks, if not months. Towards the end a hot bath, or even a dry-burn, but that's hardly a lot, either.
Helps a lot to wipe any liquid that went astray from the threads, and quite often, though. But that takes about 2 seconds when you change battery anyway.
