Formula for electric power density:
Electric power density (W/cm2) = Electrical power (W) ÷ [Heater O.D. (cm) x π(3.14) x heating section length (cm)]
Heating section length (cm) = [Heater length (mm) - 7 (mm)] / 10

IDEA NOTE Cost reduction by limiting components
Since the heater is supplemental to the cutting process, precision temperature control sensors are omitted to reduce cost.
