ーラ。 A heating means for heating and welding the resin sheet, a starting pulse generating means for generating a starting pulse when heating and welding the resin sheet, and a clock pulse that is reset by the starting pulse and inputted with a clock pulse to generate at least two types of divided outputs. Control is performed such that power is supplied to the heating means by the frequency dividing means for outputting the output and the starting pulse, and power supply to the heating means is stopped by the frequency dividing output having a shorter period among the two types of frequency dividing outputs. a flip-flop that is set when at least one of the two types of frequency-divided outputs has a longer cycle and is reset by the activation pulse; A manual impulse sealer is provided with a cooling detection means for notifying an operator of the end of the cooling time after heating the sheet.
