Requirements for grounding
To aid personal safety, proper operation, and to reduce electromagnetic interference
(EMI), the power supply must be properly grounded.
 The power supply must be grounded through the power cord according to
national and local electrical codes.
 Three-phase service must be of the 4-wire type with a green or green/yellow wire for
protective earth ground and must comply with national and local requirements.
 Refer to the Safety and Compliance Manual (80669C) included with your system for more
information on grounding.
The system’s rated output (cutting power)
A plasma system’s cutting power is determined more by its wattage output than by its amperage
output. The rated output for this system is:
 10 A – 45 A maximum output current
 145 VDC maximum rated output voltage
 6.5 kW cutting power
To determine the cutting power in watts (W), multiply the maximum output amperage (A) by the
maximum rated output voltage (VDC):
45 A × 145 VDC = 6,525 W (6.5 kW)
Voltage configurations
The system automatically adjusts for proper operation at the current input voltage without requiring
any switching or rewiring. However, you must:
 Install a set of consumables in the torch. See Step 1 – Install consumables and activate
torch on page 46.
 Set the output current using the adjustment knob on the front panel. See Step 6 – Set
mode and adjust output current (amperage) on page 51.
To operate the power supply at full output and 50% duty cycle as rated, you must size your electrical
service accordingly. The following tables show the maximum rated output for typical input voltages.
The output setting to use depends on the thickness of the metal and is limited by the input power to
the system.

The recommended fuse/breaker sizes account for spikes in input current
that occur when you stretch the plasma arc. Stretching the plasma arc is
common in some applications, such as gouging.
