A triac (triode for alternating current) in a heat gun functions as a semiconductor switch that controls the flow of electrical current to the heating element. When the triac is triggered by a control circuit, it allows current to flow in both directions, effectively regulating the power supplied to the heating element and adjusting the temperature. By rapidly switching the triac on and off, the heat gun can maintain a desired temperature or heat output. This electronic control allows for precise adjustments and efficient operation of the heat gun.
