2 – Power Supply Setup
Determine the plasma system’s cutting power in watts by multiplying its maximum output amperage by its maximum rated
output voltage:
30 A × 83 VDC = 2,490 W (or 2.5 kW).
Table1 – 120V/20A
Table2 – 120V/30A
Table3 – 200V – 240V/16A
Table4 – 200V – 240V/20A
CAUTION!
A circuit capable of 120V/20A or 240V/20A is required for proper operation. Protect the circuit
with appropriately sized slow-blow (time-delay) fuses or circuit breakers.
