I recently started building new coils in used OCC coil body's and something strange happend. It didn't quite explode but I don't know how else to describe it. I went to take a hit and as soon as I hit the button it blasted air into my mouth so hard my cheeks are sore. There was no burnt taste and It didn't pop the coil. It still fires up but I'm afraid to use it. Does anyone know the cause or how to avoid this happening again? Just FYI the coil is 26ga .76 ohms running at 39W
