Fix Your Coil in Seconds with These Handy Tips
Vaping can be easy and convenient, but when you start out you may come across a few hurdles that seem overwhelming. Depending on the type of vape device you use, the problem is often with the coil connection and repair will vary slightly on each mod.
Many of the problems are easy to fix and you’ll be vaping away again in no time. We’ve put together this checklist to help you on your way and you’ll learn the skills needed to master vape repairs yourself. The following information is related to installing coils for RDA’s, RTA’s and RDTA’s, there is also information related to testing pre-built coil connections at the end of the blog.
Get into the Habit of Preventing Problems
Get into the habit of checking your coils before you even put it all together. Put your new coil on an ohm reader or regulated device and if it reads anything else but what you expected, it could have a problem. The connections may be loose, it could be shorting somewhere, or it could just be a dud coil. It’s best to find this out before you start pouring e-liquid anywhere near it.
Before you use your freshly installed coil, the resistance needs to be checked and hot spots removed. This allows your coil to heat evenly and and contributes to a pleasurable vaping experience. the below information is for installing dual coils.
- Install the coils and ensure they have been secured tightly within the clamps/screw holes of the RDA, RTA or RDTA. Once the coil is sitting nice and secure, the legs need to be removed using wire cutters. it is important to have a similar leg length for each coil as the leg carries the electrical current and if the legs are different lengths, the electricity has longer or shorter to travel. this can lead to the coils heating up unevenly.
- the coils should be lined up so they are reasonably level and are the same distance from the posts or clamps. they should also be at the same height relative to the base of the juice well.
- Insert a coil jig or ceramic rod into the coil and bend the coil so it lies horizontally to the base of the juice well.
- once the coil has been installed, and there is some degree of evenness to the orientation, the distance from the posts/clamps and leg length. it is time to dry fire coils. Dry firing coils is an important aspect to building as it allows the user to observe whether the coil is heating evenly and helps them to identify hot spots.
- To dry fire a coil, attached the rda/rta or rdta to a regulated mod and adjust the wattage to a low value (20-30 watts). Fire the device when it has no cotton installed and pay attention to how the coil glows, if the coil is taking a long time to begin to glow, it is possible to increase the wattage to complete this faster.
- look for areas in the coil that are glowing a lot brighter than other areas. these are where the hotspots of the coils are.
- to reduce the hotspots and create an even glowing coil, ceramic tweezers should be used to strum the hot spot areas until an even glow is achieved.
- once the hot spots are removed, it is important for the user to check that the coils are heating from the centre out and at similar rates.
- once the coils are heating evenly and they are cool enough to touch the cotton and be installed.
Use This Checklist
If you think you may have a connection problem, follow this checklist to pinpoint the problem.
- Is the connection secure? In an RDA/RTA or RDTA, make sure the screws are tightened securely to create a solid connection. in a clamp build deck, you want the wires to be sitting side by side. for a single hole post you want the coil legs to sit on top of each other. Get into the habit of checking the screws after the the coil has been dry fired to ensure the coil is seated securely.
- Are Your Coils Symmetrical? If your coils vary in size, orientation or distance from the posts, uneven burning can occur. Ensure that number of wraps you do for each coil is even and they are sitting at the same height from the juice well and similar distance from the posts.
- Is a Coil Shorting? Your coil could be too close to a post, too close to the cap or arcing out which will cause a short. The only areas where your coils should be in contact with are the posts/clamps going into the deck. If you see your coil is too close to something, pull it away and get into the habit of checking this regularly.
- Check for Debris on the Deck. Occasionally stray pieces of wire may get stuck to the deck and cause a short. You can use your fingers or tweezers to remove any stray pieces.
- Inspect Your Post Hole for Old Pieces of Coil. Old pieces of coil can get left behind and you should check for this when changing coils. Again, a great option is to use a magnet to detect any old bits of wire.
- Have the Coil legs Been Accidentally Cut? This can happen while you’re stripping off the excess so don’t rule it out. If this has happened, you’ll have to start again wrapping a new coil.
Pre Built Disposable Coil Issues
Usually problems related to Pre-built coils are a lot more simple and easier to fix. Check that the coil is seated correctly in the tank and the threads have been tightened so the coil is secure. if the coil has been cross threaded, there is a high likelihood of leaking and an inability to fire the coil. When changing the coil it is worth checking the quality of the O-rings as a decaying O-ring can lead to leaking. It’s good practice to use an ohm reader or regulated device to check if the coil is close to the resistance stated on the packaging. This may help you determine an issue before you fill the tank with e-liquid.
