How the hell are we gonna share a cobra? I think Moo and tmcase tried this with a provari phineer or something like that. If I remember, Moo won.

Actually I think you are referring to sashwa and my provari. We were both curious about the provari and before I purchased one I told her we could share. But apparently I don't share well because, well I didn't share.

ONE MORE DAY LEFT :p

Then maybe you would share your Cobra so I could see what all the hoopla is all about. :blink: Nah...I didn't think so. :D

Got my Cobra Xmas eve.....3 wicks and 4 coils out of the way....Vaping great on everything except Provari,keep getting error codes,even with voltage all the way down.
Any suggestions...please.

Yes someone please make suggestions. I have heard they are better with mechanical mods, but I have also read several people talking about how they rock on provari's. I do not have anything but my provari, so I am hoping someone will come by and give you some tricks and tips so I can read them as well.

I have two cobras. One provari. Jojo stole my other provari and please don't ask how many she has. :|

I have one cobra on my provari and the other on a lava tube. If you own both, you know they are temperamental in their own way. But I get the m ROCKIN on each. I can use either cobra on one of my mech mods (GGTS) when I want too. But they will be fully dedicated to other RBAs soon.

Here are some points I've seen.
- torch that wick. Especially pay attention to the section that is above the tank where the coils will be. The top half.
- don't "choke" the wick with your coils. The odds of a hot spot cutting into the mesh increases and then the layers as it it cuts in will cause the shorts. The thinner the wire, and the finer the mesh, the more prone this is to happen. (32g wrapped tight on 400/500 with light oxidation will cut into it). Take the wick out, wrap it and reinsert it. Let it almost naturally spring back which sets up the perfect spacing. Connect. You should be able to gently remove the wick from the coil, certainly with twisting.
- coils that pull away too much? Twist the wick to rotate it in place. You'll notice the wires to even themselves off.
- hot spots....the coil below the glow is usually your problem. Remember to nudge. And another bonus to letting it spring back....nudging is easy. Think about it. If its too tight, you are dragging it along the mesh. Each nudge you make when it's too tit means you touch the mesh with whatever tool you use and potentially create a new possible spot for a short.
- another thing....if the errors continue, check between the ground screw and the wick. Slip a tiny screwdriver between that screw and the wick. It'll out that tiny space back in and prevent any of the bottom 3 coils from touching that screw. (This depends on how many coils you use. I use 30 or 28g and need many coils)
- the thicker the wire the easier to avoid problems BUT the more difficult to wrap. 30 is awesome.
- twisted wires are more forgiving. If you don't mind a lower res, but want the 32g or that's all you have, you can twist them nicely together and coil away
- I don't normally torch/light my wire anymore but if you keep struggling that may help

Provari's are very finicky with error codes, they are the most reliable VV mod because of the insane protection the error detection gives. This can make them a huge PITA with gen atty's. The Cobra looks really pretty on a provari though and when you do get it right it vapes like a champion.

I think the most important thing is finding the style of build that works for you, The bobo AD method of wrapping everything first around a paper clip works for a lot of people, you can easily check your wick and coil out better when it isnt attached to the mod to make sure everything is even.

This works well for me on mechanicals, but I couldnt ever get it to not error out on my provari, until I tried the petar K Method, it seems complicated when you first watch the youtube tutorials on it, but after trying it I hardly even oxydize my mesh anymore and it takes less than 10 minutes from start to finish to have a perfect wick and coil for me now doing this. You don't need to use a drill bit if you dont have one, the real trick that isnt mentioned in any of the videos is that you need to make sure your wick is the same size as whatever tool you use to build the coil on. that way it slides in perfectly after you dry burn your coils to make sure everything lights up evenly.

Petar K

The DrillBit Method - YouTube

and although this spreadsheet is specific to an Ihybrid, A lot of the info is pretty universal for gen atty's. If the solution to a problem with a gen atty isnt in one of the links on this spreadsheet, chances are you wont find it anywhere else either.

My Cobra's working great on my Provari. Those are some top quality tips by Yankeebobo. I have a couple to add:

- If it keeps shorting, drain the tank and dry burn it. Start at a low voltage and work your way up to your operating voltage. Burn for a couple seconds and give it five seconds to cool down between burns. This is how I solve 90% of my issues. Most of the time a couple dry burns will fix a short. If not, then move the coil that is shorting and try again, but usually it is not necessary to move it. The short is at the spot where the coil changes from red to not red.
- Don't torch your wick too much. It should be brown not black. I use a regular old Bic lighter and it works great. Don't quench it, that doesn't do anything.
- After you fill the tank and the wick gets wet, none of the coils should glow red. If they do that means they are too loose and not touching the wick.
- Don't let your wick touch the center post. It's not so much an issue with a single wick but if you use a U-wick there is not a lot of room.
- If the wick is bent, crumpled, or lumpy, that part of the wick will short. The part touching the coil must be a nice smooth cylinder.

Ok. I've got 5 days off in a row. And I've wanted to try fully the Petar K with an ever so slightly torched wick. So off I went.

- cut my mesh and torched it
- rolled it on a medium paper clip, torched it
- set aside wick
- took the yellow cobra tool, wrapped 7/6 30g on the tool (ended at 1.8ohms)
- inserted tool into cobra, leave tool in place
- make the connections, space out any coils if you want to even it out
- gently twist out the tool and leave coils as they are
- trim down the ends. Now I don't twist them off, I trim and leave a tail for any adjustments I need
- drop provari to 2.9v. Pulse fire a few times at a second each. Add a couple/three to the end at longer fires. Check ohms.
- insert your wick into place. And here I mean it will ALMOST drop in so you may want to roll the top portion of your wick a little less.
- test ohms, test fire, check glowing.

I had ZERO hot spots. None, nada, zilch, zippo. I mean NO hot spots. I dropped some juice on the wick and repeated. Got one E1 error. Rotated/twisted wick ever so slightly (1/8 turn) and E error was gone. Filled tank with my peppermint chocolate. Started at 3.3v and worked my way up to 3.7v. Ill probably go up more in a bit. Currently it's 7.6W. So it's still under where I generally like it.

It was easy. TOO easy. I'm waiting for the shoe to drop. Mind you, I thought my other method of wrapping on the coil was easy too. The one thing I could have done differently there was to drop the wick, connect, then remove the wick for some dry burning.

I'm going to try this in my other cobra now.

People always say they hate telling people "I told you so" they are liars, in reality we all really enjoy being right.

I'm a honest kinda guy, so I say with great pleasure:

I told you so :D

Yeah yeah. One thing I don't like, and it's the reason I didn't try before, is it can change the way I coil. Granted, if I'm at work and I need an emergency wrap, I can still wrap the coil on the wick. Now granted its a seasoned wick by then so it won't matter as much. I do hate needing to wrap in more tools and tools. I prefer grabbing my wick and wrapping it. The fewer tools, the less I need my toolkit.

Thats why I use the allen key that I need to loosen/tighten the negative post anyway, no extra tools needed lol.

I agree. That's why I carry allens as well. You have to to a point with gennies. Kinda burns me that I have to carry so much anyway as each is a diff key. But I'm wielding down the gennies I use that perform exceptionally well, to those that just perform good.
