Hi, newbie basics this ...
I'm making a hot wire cutter for a building application that is to have a 600mm+ wire.
Most modellers' cutters are nearer the 150mm mark.
There are obviously various different ways to combine power output, wire length and wire thickness, to achieve different temperatures in the cutting wire.
One example found recently is 9 Volts, 2 Amps, wire diameter 0.25mm and wire length 130mm.
Assuming this set up can deliver the right temperature will I be able to achieve the same heat output in a 650mm long wire (5 x the 130mm) by either using a 1.5mm diameter wire, or forming a thicker wire with five of these 0.25mm wires twisted together ... to change the resistance ... ?
Probably a no-brainer to anyone reading this so please excuse the simplicity of the question!
