Really Weird Incident with HH357 and P+ 18500

[dcannon1]

So I got an HH357 2.0hm the other day and I've been using it on my Provari, works great. I thought hey, let me give this a shot on my P+ 18500. So I screwed it on and went to take a hit. The switch instantly became stuck and the battery started getting warm. Really quick unscrewing work from me prevented any sort of damage to anything as far as I can tell. I thought, hmm that was weird. I guess I got an atty short and a stuck switch at the same time (the switch has never been anything but perfect before and after though). The atty seems OK I put it back on my Provari and check res, right at 1.9, where it was before, still vapes perfect, no errors on the Provari (and you know how sensitive Provaris can be to any sort of shorted or damaged atty/carto). So I think OK, something is going on here. I let it go for a few days, enjoy my carto tank on my P+, no issues and I enjoy my HH357 on my Provari, no issues. So once again I got to thinking, I must have just had some sort of weird bad luck the first time, maybe my spring got jammed or something like that on the P+. So I just decided to try it again and the same thing happened. I pressed the P+ button and it instantly locked and the batt started getting warm. I was ready this time and had the top cap off in about 1.5 seconds. I've tried about 10 different cartos/attys on the P+ and nothing like has ever happened before.

Has anyone else experienced anything like this?

I think I may have found the answer. It looks like the pin on the 357 is pushed in, just ever so slightly, so it looks like I was getting an atty short. I probably didn't notice this on the Provari since it seems like it always make a good connection, even if pins are pushed in (not sure why).

So that explains what happened regarding the short, but why would the button stick whenever I get a short?

I have had it happen, the 510 connector on the precise can push the center post of the atty up if it is overtightened, and depending on the atty it wont take much for that to happen, it is also possible that the attys center post will bounce back so when you remove it, you would not be able to see where it was shorting. It also sounds like your spring may be partially collapsed so you probably need to get a new spring. I would contact David to find out about getting a new spring or go to the hardware and try to find one that fits. Just for safety sake I would not use that atty on the precise which I am sure is your plan anyway. I suppose if you didnt tighten the atty down hardly at all you may be able to use it but its not worth it imo. Somewhere along the way of that atomizer being screwed in, that centerpost is pushing over enough to touch the negative, you might be able to pry the center post out a bit and screw in loosely to the precise but that is a enter at your own risk type thing. Good luck.

WEll I guess you posted before I finished my post but the button sticking is froma collapsed spring, it acts sort of like a fuse that collapses from the heat of the overdischarging battery. Get a new spring and you should be good to go, also if you have a multimeter check to see what that batt is reading. Glad you figured it out.

You had an atty short out. The button sticks not because of the spring, but because of the short. When it shorts, tremendous electrical current is released and when it tries to find its way back to the negative side of the battery, it jumps the gap between the button and shield and can cause arching and essenstially a micro weld happens. You'll often see a black spot on your button. You can touch the button up with some fine steel wool. The spring is probably fine, if not, replace (we also have heavier rate HD spring). Replace atomizer and vape away.

Thanks for the good explanation. I was sort of figuring something like that was happening, but I didn't have enough electrical knowledge to know if current could actually do that or not. I took everything apart, inspected it, gave it a quick wipe down with a cotton cloth and it's working just fine with another atty. I'll make sure to be more diligent about inspecting my attys/cartos before using them, especially on a mechanical mod from here on out.

thanks for this thread! it helped me with a similar issue!

Huh, thats crazy, I was always told it was the spring collapsing but obviously I was told wrong.

btw sorry for spreading misinformation.

No need to be sorry, you didn't do anything wrong. It may well be that way on other mods, so you were just trying to help which i TRULY appreciate as owners input in helping customers is a huge asset to the community!
