Cutting with the Hot Wire Bow Cutter 24"

Last updated: Sep 11, 2024

The BC24 Hot Wire Bow Cutter can be your go-to tool for cutting large foam shapes. It is ideal for a variety of uses, from shaping & theming creative sculptures to slab cutting EIFS on construction sites. The BC24 is lightweight and allows you plenty of free form movement, especially when working on any larger sized foam blocks. This tool can be used to make articulated cuts through foam material. The BowCutter can be mounted on either robot, but the work envelope has significantly fewer obstacles around HAL than around TARS. Therefore, we recommend using HAL for most operations.

Always use personal protective equipment when running the robots, particularly with the Bow Cutter

Safety Tips

  1. Power Controller

     Use nothing longer than a 50 foot 12/3 grounded extension cord with this hot wire. Set the temperature dial on the controller to zero (0). Turn on the hot wire power controller and adjust the dial until the wire glows orange. Immediately back off the controller until the heated wire just begins to turn from orange to gray. This is the optimum foam cutting temperature of the wire.  Anything hotter will cause premature hot wire failure or anything cooler will require too much feed pressure on the wire causing premature failure. If the heated wire is too hot, the cut may not be as accurate as you would like. A wire that is too hot will melt the foam too quickly at the beginning of the cut and less quickly as the wire cools off resulting in an inaccurate cut.


    • Use only the recommended wire. (NW100)
    • Do not use this equipment in wet or damp conditions.
    • Use only grounded receptacle
    • Magnum Controller Serial: 12405

    • Perfect for foam sculptures and slab cut
    • Freeform hot wire foam cutting
    • Adjustable hot wire heat control
    • Industrial-quality aluminum construction
    • Uses standard NW100 cutting hot wire
    • Comfortable, positive hand grips

    Note: Heated Wire expands when hot. If the spring is too tight the hot  wire may break restricting operation of mechanism. If too loose, the foam cut will be sloppy. Readjustment of tension may be necessary from time to time.
