What is the principle of electrocautery

During electrocautery, the back-and-forth actions of the high-frequency alternating current make the cellular ions waver to generate frictional heat. Thus, electrical energy is transformed into mechanical then to updraft energy intracellularly. Such produced heat produces the updraft tissue effects. Blinking electrical currents with incidences higher than 100,000 Hz are not related to the Faradic effect of neuromuscular stimulus when applied to patients. In addition, the use of such high-frequency irregular currents would lead to more foreseeable and controllable electrosurgical tissue effects.
Electrocautery units (generators) made by Electrocautery Machine Manufacturers swap the low-frequency of household electricity (50–60 Hz) to higher incidences of 500,000–3,000,000 Hz. In addition, they control the wattage, power, and duty series of the current. Usually, these machines supplied by Electrocautery Machine Suppliers produce three fundamental current waveforms; cut, mixture, and clotting (coag). Modern smart producers bought from Electrocautery Machine Dealers have additional purposes such as monitoring tissue impedance to regulate their power output for unchanging tissue effects.
