Not a very helpful contribution, sadly, but that chart relates to wire
in free air (presumably). As soon as you put it in contact with the foam
it will cool down and not cut. You really need something that is
thermostatically maintained and more like a knife with some thermal
inertia.

Or, you can do like every other hot wire cutter.
It's too hot in free air, but cools down to just right once it makes
contact with the foam.
