Here's my version of a hot wire foam cutter. I use the transformer from my old electric train set and an E guitar string (.050) as the cutting element. The transformer puts out 25 watts. Does a nice job. I am making a longer cutter so I can hot wire longer sections. It will be horizontal. I am still in the planning stages, but hope to have it melting foam later tonight.
