It may seem so commonplace, now that high-performance mods can be seen in use just about everywhere, that the abundance may make light of the risks involved. This is not an attempt to scare you, however it is a public service announcement that will serve to offer some additional info and reiterate how important it is to observe certain measures of safety when using and working with mods.
First pointer: common sense. That’s one of the most important tools you can possess, especially when vaping. It’ll save you a lot trouble in the long run if you keep it in mind!
Secondly, you must know what you’re doing. In order to build coils correctly and safety, and utilize the proper batteries, you need to know your stuff, inside and out, and all the way through. No short cuts on the learning aspect; it’ll potentially save you some destruction in the future. Remember that coils are constructed of resistance wire, and that is precisely what it does; offers resistance against the electrical current pulsating through it as you fire the device. This resistance is what allows the coil to heat, and then vaporize the juice.
Short circuiting can occur here if the wire is not conducting enough heat, causing the negative and positive terminals of the battery to connect. Always pay attention to the voltage level of your battery. When it hits around 3.5 volts, change it. For this situation, it’s always a good idea to have backup batteries. And, this is also why having a multimeter is essential. The dreaded amp draw. All batteries have one, some have it clearly printed on them alerting you to this fact, and others do not, so make sure it’s evident when you purchase.
One rule regarding amp draw to follow is that the higher it is, the better. The combined ohms and voltage need to be lower than your battery’s safe amp draw limit. On a regulated device, this should all be no big deal because there are settings that handle it for you, and back you up in the event of miscalculations. With mech mods, you’re on your own because without circuitry, there is no protection built in. Now, as for safety info, we know there are plenty of other aspects and areas to cover, so let this serve as a basic, quick cheat-sheet.
In the event you are unsure of something, either do not use it, or proceed with common sense!
