3-2
The power supply must be cleaned as often as necessary to prevent the accumulation
of metallic dust inside the unit. See Section 2 for unit dimensions.
Manual Gas Console (MGC)
The MGC should be mounted near the CNC controller so that it is easy accessible by
the operator. See Section 2 for mounting dimensions.
Impulse Start Console (ISC)
The ISC should be mounted in a convenient location that is away from other electronic
control devices. The ISC offers significantly reduced emissions compared to traditional
high frequency, however, the high voltage pulse generated inside the unit may interfere
with the operation of sensitive control electronics. The ISC is usually mounted on the
gantry of the cutting machine or on the cutting table. See Section 2 for mounting
dimensions.
5-Gang Manifold
The 5-gang manifold assembly must be mounted within 6 feet (1.8 m) of the torch. See
Section 2 for mounting dimensions.
2-Gang Manifold
The 2-gang manifold assembly must be mounted to the torch. See Section 2 for
mounting dimensions.
Torch
The torch must be installed on the positioner of an arc voltage control (height control)
capable of maintaining the cutting arc voltage within 1 arc volt. The arc voltage must be
adjustable in 1 arc volt increments. The positioner must be rigid to ensure cut quality
and a torch collision sensor is highly recommended. See Section 2 for mounting
dimensions.
Cooling System
The cooling system must be located within 8 feet (2.4 meters) of the plasma power
supply. The surface on which the cooling system is located should have a grade of no
greater than 10º to eliminate the risk of toppling over. See Section 2 for unit
dimensions.
System Interconnection
The Spirit II system interconnection diagrams on the following pages will assist in the
planning and installation of the system as well as identifying cables and hoses upon
receipt.
The optional Inova torch height control is also shown to assist with its connections,
whether as an external console or internal to the plasma power supply.
