I converted the controller of an old plotter that was burned out. By trial and error method we managed to get it working.
 I use 0.3mm kanthal wire.The length of the wire is 1.5 meters.
 It does not break very often but it is almost always the least appropriate moment when cutting large files.  And my works can be cut even 1,5 h. I use styrofoam for initial molds for plaster decorations.  (Maybe a little from exaggerated economy I use it too long).
I don't know the tension force of the wire and it will be difficult for me to measure it.
I don't know the temperature of the wire either, but I know that with the hardest materials in the dark it doesn't glow. At least that's the setting I use.
The wire is powered by 90V.
I have the PWM set to 100Hz.
Whether the control is needed I don't know now I work without it, but in the old machine it was and sometimes I saved a large piece of material.
I am also attaching two photos from the manufacturer's website of my own now I don't have until the weekend I will be in the workshop.
