If you are just venturing in the realm of vaping or a seasoned veteran, you probably have heard or read about coil rebuilds to save you some money. As easy as some make it sound or look, there are numerous factors to consider before you start. One of the most important is your safety, which we will be focusing on today. But first...
What is an RDA?
Rebuildable Dripping Atomizer or (RDA for short) is the unit where you drip e-liquid directly on a coil / wick combination. It doesn't hold a lot of e-liquid like an RBA (Rebuildable Atomizer), that has a reservoir tank, but is much easier to make and change out coils, wicks and customize the Ohm output.
Safety Step #1: Prepare Your Area
In any type of DIY project, you need to have a safe and clean area to work in. More and more people have ventured into this area without being prepared and have suffered the consequences. Designate a clean dry space to be your work area. There should be no outside chemicals, water or debris present that could short out your progress resulting in damage to your equipment or harm you and others around.
Safety Step #2: Use The Right Equipment
Make sure you use the right batteries, coil material, and Ohm reader, which are all crucial to getting a safe start on your rebuild. There are different types of batteries that are used. The most used batteries are the 18XXX series of batteries. You have the option of 18350, 18490, 18500 and the more common 18650. The "18" designates the width (18MM) and the next two numbers (35MM, 49MM, 50MM, 65MM) tell you the length. No two batteries are built the same so knowing the limits of your battery is a big part of a safe re-build. The correct Ohm meter is also crucial. If you use an ohm meter that is designated for reading industrial type equipment, chances are you won't get a solid reading. There are meters that are specifically designed to work with your coil rebuild. The type of coil material is also crucial. Most commonly used is Kanthal A-1 resistance wire. This provides a more consistent reading throughout the process.
Safety Step #3: Check Ohm Frequently
Checking the Ohm before, during and after are important steps that are overlooked time and time again. There are many steps during the process that could result in a short without you knowing. This could lead to a sudden increase in current that could overheat your battery causing a fire or small explosion. There are different gauges that require certain Ohm (resistance) and if you don't check your progress from start to finish you could wind up spending a lot more money from this failure. The smaller the gauge, the more wraps, which means more Ohm check. The typical gauges are 26 or 28. These provide more consistent resistant readings.
By following these safety procedures when doing this type of DIY project, you too can become a season pro in the art of coil rebuilds.
