1. An ultrasonic electromechanical system for an ultrasonic surgical instrument, the ultrasonic electromechanical system comprising:
an ultrasonic blade;
a clamp arm disposed opposite the ultrasonic blade;
an ultrasonic transducer acoustically coupled to the ultrasonic blade, the ultrasonic transducer configured to ultrasonically oscillate the ultrasonic blade in response to a drive signal; and
a control circuit coupled to the ultrasonic transducer, the control circuit configured to:
determine a temperature of the ultrasonic blade;
increase an amount of power of the drive signal when the temperature of the ultrasonic blade is less than a first predetermined value, wherein the first predetermined value is a value less than a temperature configured to cut a tissue; and
decrease the amount of power of the drive signal when the temperature of the ultrasonic blade is greater than a second predetermined value,
wherein the second predetermined value is greater than the first predetermined value.
