A laminating arrangement includes a laminating roller, a heat source for heating the laminating roller, the heat source being powered by an AC power supply, and a heat source intensity control system for controlling the intensity of the heat source. The intensity control system includes a processor and a triode for alternating current communicating with the processor. The triode for alternating current is turned on and off by the processor to control the AC power supply to the heat source to vary the intensity of the heat source.
