What is the tungsten wire inside the hair dryer?
If only a small fan to turn, and the electric wire is not hot, then blow out just the wind and not hot.
The hair dryer is a combination of a pair of electric heating wire and a small fan. Power, the electric wire will produce heat, the fan blowing the wind through the electric wire, it becomes hot
Red is a normal phenomenon, the problem should be from the working principle of the blower
And you said "burning red tungsten wire" is actually a hot wire red is a power generated after the normal reaction of heat, so this is a normal phenomenon, please do not make a fuss.
