Rebuildable Atomizer Safety


15. Rebuildable Atomizer Safety


Rebuildable atomizers are a great way to save money, but they also offer you the freedom to tweak your device to your preferences, improving flavor and vapor production in the process. Much of the safety advice related to them follows directly on from the previous post, but there are some unique concerns too.


Key Points


  • The process of rebuilding may seem safe, but it’s essential to remember that you’re dealing with conductive wire that’s designed to get hot. Never rebuild an atomizer while it’s connected to a mod (at very least, ensure the mod is turned off or locked so the coil doesn’t receive power when you’re fiddling with it), and use common sense when it comes to things like the sharp ends of resistance wire.
  • Multimeters are useful for rebuilders, and essential if you’re using a mechanical mod. Test the resistance of your coils regularly, and remember to subtract the “lead resistance” of the multimeter (found by touching the probes together) from the reading, especially if you’re in low-ohm territory.
  • If the resistance reading drops, this is a sign of a short circuit, which may lead to battery problems as covered in the previous section.
  • VV/VW devices can often be used to check resistance, but it’s important to set the device to the lowest voltage (or power) before testing the atomizer.
  • Some wicking materials – such as cotton and silica – can’t be “dry-fired,” so it’s better to test resistance without a wick inserted if you’re using these materials.
