How do you cut the plastic and use what tool to cut the shape you want?
If the temperature is not enough, continue to add batteries.This man's method is feasible, but not very reliable. It is better to use fine wire than steel wire, because wire resistance is big, easy to heat, and higher than steel wire resistance, and hardness and tensile strength are also relatively large;In addition, the battery power supply, the cost is very high and not good control, with an adjustable transformer power supply, the effect is better.We use the unit cutting foam resistance wire, and an adjustable transformer, with a kind of tools like bow tension, voltage regulating transformer of resistance heating wire, can be cut to any shape of plastic.
Electric cutting method, with a thinner than the hair of a thin copper wire, looking for a cork bar, made into bow, copper wire when the string. Look for two dry cells connected in series at both ends of the copper wire. The copper wire will burn.
The electric heating cut uses the root to be thicker, the spot is fine, the copper wire looks for a root, the soft wooden rod makes the arch copper wire string, looks for two dry batteries to connect the copper wire, two copper wires to scald, the temperature continues enough to add the battery
