    Hello,
    I looking for some ways to fast way to warp up a heating element.
    type of my heating element is resistance and work by 220 volt power supply. ( 50/60 Hz ).
    if i increase power-supply frequency, time of warming will be decrease? ( like 220 volt 400Hz )
    i can not increase power supply voltage. what is your idea?

    thanks.

    Frequency increase won't do it.
    You could keep it semi warm with a triac and switch over to full on?

    What takes 4 minutes to get to 250 degrees C? Surely not the element. What wattage ? If it's the medium you are referring to then add another element ( 2 minutes then maybe)
