Why the vape does not produce smoke？

1. If the LED shows normal but there is no smoke under the working condition of the vape, it may be caused by the welding of the output end of the battery pack, such as false welding or leakage welding.

2. If the battery rod does not detect an open or short circuit function, the atomizer itself is assembled abnormally, there is no resistance, and other bad (open or short circuit), will also lead to the atomizer does not working.
