First heat up your coil to 800F-900F. By heating up the coil you expand it allowing more room for the banger/nail to fit. Place the banger/nail in your other hand, once the coil has been heated slowly place the banger into the coil. The coil will only cover the bottom part of the dish on the banger, do not force it. *IMPORTANT* always remember to remove the coil from the banger/domeless nail before turning off your unit. Never turn off the enail and leave the coil to cool on the banger. Once the coil begins to cool it will contract, squeezing the banger making it very difficult to remove the coil and will most likely result in cracking/breaking. Even waiting a few minutes will allow enough time for the coil to tighten around the banger/nail so we advise to remove the coil immediately after every session.
