This fits the power supply above & is the same socket that we use for our 150mm hot wire cutter. You would connect it as you would any other resistor. Finally we need to figure out the best way to create the required total resistance in Ohms (Rt) using our nichrome wire. 77. Actually SS wire (Fishing leader) has less resistance for a given length than Nichrome wire. Now in table # 2 we see a 15 AWG nichrome wire will be about 300 C at 9 amperes.. You need to measure about 1.3 ohms of this wire use wire screws solder does not work use a threaded bolt and nut.. Don't cut until you try it and don't burn yourself ! Then you can use PWM to control power to the wire, and then shut it off for a fraction of a second to measure resistance and therefore temperature. I look forward to your council. I want to draw 0.8A from my 12V power supply so I need my nichrome wire to have a resistance of 15 Ohms (12 / 0.8 = 15 Ohms). I have an old ATX power supply that could provide 12V, but it obviously can't be regulated to a higher or lower voltage without modification. DC SWITCH POWER SUPPLY... CA$210.00 Quick view ...
