Question

post-test
all of these may be used to apply heat to an aluminum panel except:
a. infrared lamps.
b. plasma cutter.
c. heat guns.
d. induction heaters.

Explanation:

Infrared lamps, heat guns, and induction heaters are used to apply heat. A plasma cutter is used for cutting (like metal cutting), not for applying heat to an aluminum panel. So the option that is not used to apply heat is the plasma cutter.

Answer:

B. Plasma cutter.
