A temperature-control circuit of a heating line and a temperature-control method thereof are disclosed. The method comprises steps of: outputting a forward square-wave signal by a first forward square-wave signal generation circuit; outputting a reverse square-wave signal by a reverse square-wave signal generation circuit; and outputting a varied forward square-wave signal by a second forward square-wave signal generation circuit. Above square-wave signal generation circuits are respectively connected with an AND gate. When the input square-wave signals are simultaneously logic high, a switch is triggered by a trigger circuit to heat the heating wire. When the heating wire's temperature increases, the forward square-wave signal output by the second forward square-wave signal generation circuit is changed so as to render these input square-wave signals non-simultaneously logic high and not to trigger the switch in order to stop the heating wire's heating and keep the heating wire at a certain temperature range.
