Cheap "variac"?

Today at a local flea market, I picked up a PRO (Made in Taiwan) Soldering Iron Controller. It has a three-prong power outlet and a heavy duty potentiometer for controlling the voltage level of the outlet. The labeling indicates "MAX. 800 WATTS-120 V.A.C." My math tells me that this unit can handle a maximum of 6 amps. Would this be safe to use as a variac on, say, a sparsely loaded IMSAI? It was only a buck.
