Uchida of America Foam Cutter, Plug in

Will this cut EVA foam ?

Received this in good time. However instructions say not to cut styrofoam. Could this be true? I bought it to cut styrofoam shipping boxes.

What is the distance between the wire and the metal upright that is parallel to it?

What wire would you recommend to purchase? truthfully your wire sucks but, without the wire, the unit is useless. help.
