Nichrome Hot Wire Cutter

Nichrome c contains 60 nickel 16 chromium 24 iron.

Nichrome hot wire cutter.

The device works by passing low voltage electricity through a nichrome wire causing the wire to heat up to about 200 c. 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. In this video i will show you how to make a bow polystyrene cutter out of pvc pipe and a household ac power adapter this is a handy little foam slicer if you. The answer is a hot foam cutter which uses a heated wire to slice through the foam.

Larger diameter wires are also used for very long cutters such as 8 or 10 feet. Nichrome wire nicr is the optimal cutting wire choice for foam cutting equipment for a variety of reasons but particularly because it is resistant against corrosion and oxidation at very high temperature. Nichrome a contains 80 nickel and 20 chromium. Bend the nichrome wire three inches from each end.

The nichrome cutting wire reaches the temperature of a few hundred celcius degrees in few seconds. Nichrome is an alloy of nickel and chromium. The hot wire foam cutter is a tool used to cut styrofoam polystyrene plexiglass etc. The device consists of a thin metal wire often made of stainless steel or nichrome or a thicker wire preformed into a desired shape which is heated via electrical resistance.

Nichrome hot wire cutter for acrylic. Acrylic sheet is always a go to for me when building something. For the past few years i ve been using a dremel rotary tool to cut the plexiglass which gets messy. A 12 piece of 14 gauge nichrome wire requires only 1 9 volts but almost 12 amps.

All metals expand with heat so the nichrome wire at cutting temperature also expands and gets longer. You can read about all kinds of things people do to power their hot wire foam cutter including things like running 110v through a light bulb in series with the foam cutter battery chargers dimmer switches variacs wall warts batteries and so on. Nichrome wire has high tensile strength and a high melting point. It has high corrosion resistant and melting point hence it is used in electric appliances and tools.

These cutters are expensive to buy but you can build your own inexpensive hot foam cutter that uses an automotive battery charger as a power supply. Make a hot wire foam cutter the hot wire foam cutter is a tool used to cut polystyrene foam and similar types of materials. The tension factor. Hot wire foam cutter power supply design.

Insert the ends through a hole at one end of each metal. Nichrome is wound in coils to a certain electrical resistance and current is passed through it to produce heat.
