2 – Power Supply Setup
Position the plasma cutting system
 Position the plasma system near an appropriate power receptacle. The system has a 3.0 m (10 foot) power cord.
 Allow at least 0.25 m (10 inches) of space around the power supply for proper ventilation.
 When positioning the plasma system, be aware that excess moisture from the internal compressor exits through a
hole in the base, underneath the power supply. You may see a small puddle form under the power supply as you
operate the system.
 Place the power supply on a stable, level surface before using. The power supply can tip over if set at an angle
greater than 10 degrees.
 Do not place the power supply on its side. Doing so can prevent proper air circulation needed to cool internal
components. It can also divert air away from the torch and prevent it from working properly.
 Be aware that when you operate this system at altitudes higher than 2,200 m (7,500 feet) above sea level, you may
experience some reduction in cutting performance due to the adverse effect that altitude has on air compressors.
 Do not use the system in rain or snow.
Prepare the electrical power
The system’s maximum output voltage varies based on the input voltage and the circuit’s amperage.
Additional factors must be considered when you are operating the system at an input power of 120 V, as tripped circuit
breakers can result under some conditions. For more information, see
System operation guidelines on page 49 and
Troubleshooting guide on page 63.
Voltage configurations
The system automatically adjusts for proper operation at the current input voltage without requiring you to perform any
switching or rewiring. However, you must make sure that an appropriate set of consumables is properly installed in the
torch and the amperage adjustment knob is set to an appropriate output current. For more information, see
Step 1 – Install the consumables on page 43 and Step 3 – Adjust the output current on page 45.
The following tables show the maximum rated output for typical combinations of input voltage and amperage. The output
setting you need to use depends on the thickness of the metal and is limited by the input power to your system.
 Hypertherm does not recommend operating this system on a 120 V / 15 A circuit.
The Hypertherm rated output is:
 15 A – 30 A maximum output current
 83 VDC maximum rated output voltage
 2.5 kW cutting power
WARNING!
CHANCE OF ELECTRIC SHOCK
Never cut under water or submerge the torch in water. Electric shock can cause serious injury.
