Test your safety knowledge!

[crxess]

Hmm.

Its worth remembering that the vast majority of early explosions were caused by cigalikes. I think its conceivable that a .2 mech on a authentic VTC4 could be considered safer than a cigalike?

Don't know that I can concur for a few reasons.
1)VTC4's(Authentic) are almost non-existent leaving many purchasers with a re-wrapped 20a battery.
2) A .2 ohm coil is only as good and accurate as the builders capabilities.
3) Almost ALL cigalike explosions were Faulty Charging related, not actually through usage.

Not arguing the point, just pointing out the arguments.

Aw heck...I've thinking about going an rba, the youtube folks make it look so easy! Glad I stumbled on to the post...will educate myself first. Thanks.

I've never heard of a cigalike explosion that I can remember.
Unless you're talking about Egos, and about fires?

Actually I want to vape not become an electrician.

 

[wheelie]

I have to use the vape calcs, because I don't know the formula -- and no, it would do no good at all to repeat it at me to infinity, because it WILL NOT STICK. Not even if I use different letters.

It's the same reason I had to get an Omnitester instead of using my husband's nice multimeter -- I don't know what goes where (also why I'll never understand football... I don't know who goes where and why, nor why 10 yds is a "down," nor why a 3rd down is different from a 1st down... it's 10 yds! That's all I know! Spare me the details because I don't care anyway! I'll holler when everyone else does!).

But you do watch football to see all the guys patting each others behind after every play. LOL

They don't even have to pat, most of them have fairly oogleable behinds just from wearing those tight pants. I always enjoy watching the endzone antics, some of those guys are so goofy. But mostly I ignore football, unless a team I like is playing, then I'll give a solid "yeah!" when I wander into the room where my husband is invariably watching it. I particularly enjoy the Bengals' helmets, the font on the Ravens' jerseys, and the whole color scheme the Saints have going on. Plus Drew Brees is just so dang cute, I want to adopt him.

Fixed that for you.

well if you want to vape using a mech mod, then you need to do it smart. you need to at LEAST know how to calculate using ohms law.

17: You wind a .4 ohm coil, mount it in your RDA, wick and prime it then remount the RDA on your ohm checker just for peace of mind before mounting it on your brand new authentic 100%red copper mechanical for the first time. You know your authentic Samsung 25R's are fully charged and you lick your lips in anticipation of your first vape on you brand new DREAM rig. The ohm checker, however tells you your coil is now reading .2 ohms.

What do you do and Why do you do it?

You get out your 1% precision resistor and read its resistance. That will reveal which meters are calibrated properly (if either).

After slightly separating the coils and discovering that your coil is now within range, you will heat the coil to a glowing red state with your torch to oxidize the wire and prevent coil shorts (which could have happened during handling). Then you compress the windings together with your ceramic tipped tweezers. Hopefully, after that your coil will read something around the .4 ohm resistance you intended to create, now that you know which meter is reasonably accurate and that the wire is insulated from oxidation.

here it will do it for you.. Steam Engine | free vaping calculators

I'm sorry I'll just be a ignorant hazard to society. Because I doubt I will ever bother to memorize enough of that crap to ever pass your test.. I've read it I understand it I can't explain it, I don't need to do the math there are calculators for that. I just need to know that there are LIMITS to vaping, and that I need to check that I stay within those limits.... I do not need to know WHY of everything. I only need to know where safe ends and UN safe begins.

Edit: Nevermind, I am repeating myself.

 

[SissySpike]

I guess I do expect a bit too much from people. keep in mind it is part of my job to understand ohms and watts law, so my brain is a bit skewed.

Im a Iron Worker Here I am doing my balancing act about 150' off the ground and here is one one the biggest concrete water reservoirs in Ca I put a alu roof on it it would be silly of me to expect everyone to know how to do what I do and a little condescending to say I expect everyone to have the skills and know how I have.

So its safe to say I would starve if they asked me to do your job, but you might not make it out alive if you tried to do mine. I can not answer most of your questions but I know how to use vaping equipment safely. I was around when we were pushing the envelope with none of the great stuff we have now I did not hurt my self or burn my house down that was not by accident.
BTW I use to date a lady from Medford she was pretty wild;-)

 

[Thrasher]

How do I answer the question if I don't squeeze coils with tweezers.?

I been wrapping for so long I don't even measure them anymore lol I can tell by the number of wraps vs reaction time within a .1 most times. But then agai n I'm not into .2 ohm coils and super amp madness.


(If someone says hangin with the posse again I'm gonna start punchin kittens)


What happens when you stack batteries? Ummm you get a longer one lol

All this wire length calculation junk.... What happened to wrapping a coil and measuring the resistance? If people learned more about tuning the build they wouldn't need to perfectly calculate a.2435664 ohm coil. Once you wrap the same coil freakin 20 times the end result should start to sink in on its own

I would never trust that calculation, even the wire makers say r per foot is nominal and there will be variations in wire thickness.
I do agree we don't need all the theories but I also believe you should not blindly trust someone else's conclusions with regards to resistance measurements and safety buy a meter, do it yourself. Set. Check,done.

As long as people can understand their batteries and use an ohms law calculator they should be OK.


And like you I don't expect others to have my skills or me to have your level either ( I'll stay on the ground thank lol)

 

[DaveP]

Without tweezers you would just rake your fingernail lightly across the coils while it's on the resistance checker until it shows the resistance that you actually wound. That will slightly separate the coils and allow you to dry burn it without drawing too much current. Several short pulsed dry burns to a red glow will create an oxidized layer on the wire that naturally insulates the coils from each other (kind of like soot on a burning log). That will allow the coils to touch lightly without shorting when you apply power.

I can see the OP's reason for posting the problem. There's not much room for shorted turns in a coil when you are working that low in resistance. Going from .4 to .2 ohms doubles the already high current level and might just turn your battery into a roman candle. Being at 1 ohm might keep you at .5 ohms with a coil short in this hypothetical problem. The lower you go, the easier it is to miscalculate.

16: Your out with the Posse hanging and blowing clouds.... You load up the topper, grab a lung full of air, press the fire button on the mech and try to draw in a full lung full of vapor but nothing happens. This happens too you twice in 10 minutes. Your next step is to:

a: try again....It's just an intermittent problem.
b: adjust the switch, visually inspect the batteries and topper for an obvious problem and try again.
c: switch to your backup rig until you can get home and find the root cause of the problem.

D. Have one of Ur "bros" explain to you that Ur an idiot and you have to exhale before you can inhale again.

buy a better multimeter

It was a 2 part question, dear.

Your score is 50%.
