PROBLEM TO BE SOLVED: To provide a method of operating a resistance heating apparatus in reflow treatment equipment in which an induction heating apparatus is installed more in the existing equipment having a resistance heating apparatus and is used with the resistance heating apparatus in combination. SOLUTION: The induction heating apparatus 17 for heating an electrolytic tin plated steel sheet 11 with the resistance heating apparatus 14 used in combination therewith is installed more between paired energizing rolls 12, 13 of the resistance heating apparatus 14 and just upstream from a quenching tank 15 in the existing equipment for carrying out reflow treatment by directly resistance-heating the electrolytic tin plated steel sheet 11 by the resistance heating apparatus 14 to melt tin and quenching the electrolytic tin plated steel sheet 11. The voltage V' applied to the resistance heating apparatus 14 after the installation of the induction heating apparatus 17 in the reflow treatment equipment 10 is set to a value in a control voltage range calculated by multiplying applied voltage V in the operation of the resistance heating apparatus in the existing equipment by≥0.9 and≤1.1 coefficientαand coefficient K including the induction heating condition.
