  1. Choose any thickness of wire— from .005 to 0.25. Thin wires are safer and cut cleaner, but they sag and break if stressed. Large wires are more durable.
  2. Use the transformer and control unit shown.
  3. Design a fixture to hold the wire— use a spring to hold a constant tension in the wire.
  4. We offer components only— not instructions for building. This schematic is shown only to indicate how a system could be configured. Consult an electrcian or electrical engineer for proper wiring and setup.
Model 18TP Control Unit:

Model 18TP unit includes a standard grounded plug on a six foot power cord and a three-prong receptacle for quick and easy line and load connection. A lighted rocker switch turns power to the unit on and off; a case-mounted, easy-to-operate 270°-turn potentiometer provides variable control of the RMS output voltage. Unit chassis are designed for portable use or 2-hole fixed mounting.
