wire foam cutter is used to “cut” patterns out of foam.
In reality no cutting takes place. A wire is
stretched between two points and then connected to a power source.
When power is applied the wire resists the flow of energy and
gets hot. The foam is then fed into the wire
causing it to melt resulting in the ”cutting”
are many versions of this machine. Some simply
stretch a wire between two pieces of wood and connect it directly to
110v. NOT a good idea as this WILL kill you if you
are not careful. Some connect their cutter to a
battery and some to the battery charger. The
commercial machines use a dedicated variable power supply.
chose to use my battery charger for the power source since it spends
most of its life doing nothing and was paid for. Now
we can connect the cutter directly but this will cause the wire to get
very hot and can distort the foam. Not to mention
reduce the life of the wire. The simple easy
solution is to use a standard light dimmer and receptacle to plug the
design of the cutter also leave room for
interpretation. I am currently experimenting with a
design and will post pictures when I have something I like
