- Choose any thickness wire from .005" to .020" diameter. Thin wires are safer and they cut cleaner— but they sag and break if stressed. Larger wires are tougher.
- Use the transformer and control unit shown.
- Design a fixture to hold the wire— use a spring to hold a constant tension in the wire.
- This schematic is shown only to indicate how a system could be configured. Consult an electrician or electrical engineer for proper wiring and setup
