Own Foam Cutter
| 1. 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. 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. This schematic is shown only to indicate how a system could be configured. Consult an electrician or electrical engineer for proper wiring and setup. |

120 Volts AC 50/60 Hz, 10 Amps, 1200 Watts Power Circuit: power semiconductor with parallel r-c circuit. Control Circuit: all solid state circuit for stable, full-range control. Mains Frequency: 50/60 Hz. Output Voltage: 0-95% of input. Overall Efficiency: 99%. Power Loss: 1.5 wafts/amp. Control Input: variable resistance, 270°-turn potentiometer. Control Power: 1 watt. Fuse Protection: special “2 millisecond” fuses are factory-tested and coordinated to protect the power semiconductors from short circuit faults. Input Connection: grounded three-prong plug. (NEMA 5-15P @ 120 VAC, or 6-15P @ 240 VAC) Output Connection: three-prong receptacle. (NEMA 5-15 @ 120 VAC, or 6-15 @ 240 VAC)
|
| Model 18TP unit includes a standard grounded plug on a six foot power cord and a three-prong recep- tacle 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. |
