I am starting to think that is how it is done. just heat the wire
and watch the cut.

I don't suppose it is anything difficult as I am trying to make it.

I was envisioning using a feedback so the cutting would slow when the
wire cooled, and/or adjust the current automatically.

I used to cut out lots of foam wings for RC airplanes way back yonder,
and I did it exactly like Phil describes. Worked just fine.
