Nichrome Hot Wire Cutter Calculator

Nichrome hot wire calculator use this online nichrome hot wire calculator to calculate the total resistance resistance per feet the power required the current required and volts of a nichrome wire with ease.

Nichrome hot wire cutter calculator.

Set three calculate the fourth. The tension factor. 75 x 12v x 2a 18 watts 18 watts 1 5 watts per inch 12 inches. Nichrome is wound in coils to a certain electrical resistance and current is passed through it to produce heat.

There are two readily available types of wire nichrome a nichrome c. So lets say we want our hot wire length to be 100mm long which is 0 1 of a metre and we know the total resistance needs to be 3 43 ω. Each affects the others. All metals expand with heat so the nichrome wire at cutting temperature also expands and gets longer.

So if we multiply our 3 43 ω by 10 then we should get the resistance we need per metre. Voltage gage length and temperature. A 12 piece of 14 gauge nichrome wire requires only 1 9 volts but almost 12 amps. Power source and hot wire.

On our nichrome wire page we have added the resistance ohms per metre next to each wire. Easy hot wire cutter guide ac adapter guitar string or nichrome. My power supply is a 12 volt supply rated at 2 amps will it be adequate for a hot wire cutter calculation. Use this online nichrome wire calculator to calculate resistance power current and voltage of the nichrome coil by just providing the length thickness and temperature of the nicr.

This calculator provides you the above mentioned details for both the nichrome a and nichrome c wire. My design is simple no tables no springs no dials just the raw guts. This instructable is different than previous ones because it uses hot wire cutter design charts to ensure the perfect finish. Nichrome c contains 60 nickel 16 chromium 24 iron.

The nichrome cutting wire reaches the temperature of a few hundred celcius degrees in few seconds. Use this calculator to find the right nichrome wire size length and power supply for your application. There are four variables involved in determining what you need. I chose nichrome wire as the example to show how nichrome wire temperature can be calculated using a sp.

Nichrome a contains 80 nickel and 20 chromium. Nichrome wire is the optimal wire choice for foam cutters for a variety of reasons but particularly because it is resistant against corrosion and oxidation at very high temperature. Nichrome wire has high tensile strength and a high melting point. This is the first video in my new wire design series.
