"Which Voltage do i need to cut Styrofoam with a resistive wire"
- CRConrad 3y agoThe voltage in your wall sockets is a given, so the question should be "Which resistive wire do I need to best cut Styrofoam with electricity?"
- gruez 3y agoThe low iq solution would be to steadily ramp up the voltage until it cuts.
- doubled112 3y agoHah, apparently I am low IQ but still getting it done.
- doubled112 3y agoDo I need to give you a number? Can I just build something that allows me to control voltage and turn it up until it cuts, then measure?
- Avicebron 3y ago240V, that's an unfair example. As a low IQ person, I sidestepped trying to actually calculate the heat generated by different resistive wires (has to be above the melting point of styrofoam) and thought linearly about what I wanted to do, which was cut styrofoam, so google styrofoam cutter hot wire, got me to amazon.
- blueflow 3y agoCorrect answer would have been "I don't know, whats the resistance of the wire". 1.2 Ohms per meter, 45cm (which was what i had) would burst in a flash of liquid metal when connected to 240V.
- Avicebron 3y agothe correct answer is to cut the styrofoam. https://www.amazon.com/Foam-Electric-Cutting-Machine-Controller/dp/B0BL7ML3K1/ref=sr_1_5?keywords=hot%2Bwire%2Bfoam%2Bcutter&qid=1706622844&sr=8-5&th=1 https://www.amazon.com/Foam-Electric-Cutting-Machine-Control...
