Generally you use a hot wire cutter to make flat profile cuts through foam. With Proxxon’s new ThermoCut 12/E, you’re not just stuck with a boring straight profile — you can bend the wire to cut almost any profile you can imagine.
A U-shaped fixed frame has a pivoting and adjustable length arm on top, and an extendable lower arm holds the hot wire. The arms extend far enough to cut as deep as 7.9″ into the foam and you can cut foam as high as 5.9″. The wire heats up in only a second, and you can vary the wire temperature to fine-tune the cut.
You can pick up the Proxxon’s hot wire cutter with 5 shapeable cutting wires starting at $50. Using the hot cutter requires the additional purchase of one of Proxxon’s power transformers such as the NG2/s, which’ll cost you at least an additional $21. As long as you’re at it you should probably pick up some additional cutting wire for about $20 or so.
