System Description
The Spirit II 400 is a 400 amp microprocessor controlled, 100% duty cycle high current
density plasma cutting and marking system. It utilizes a precision, dual gas torch that is
capable of cutting mild steel up to 3" thick and stainless steel up to 1-1/2” thick.
The system contains a manually controlled gas console, which also provides the
primary interface to the entire Spirit system.
The Spirit II system is available with an Arc Starting Console (ASC) that utilizes
CleanStrike
™
technology, which results in reduced EMI and thereby minimizes
interference with sensitive electronic equipment.
For cutting mild steel, the system uses oxygen for the plasma gas and either oxygen or
air for the shielding gas. When cutting stainless steel or other non-ferrous materials, air
or H17 (17.5% hydrogen, 32.5% argon, 50% nitrogen) is used for the plasma gas and
either air or nitrogen is used for the shielding gas. Oxygen and nitrogen are used for
the preflow and postflow gases.
The torch is water-cooled and consumables are machined to exacting dimensions and
checked with the latest computerized measuring systems. Nine nozzle sizes (30, 50,
70, 100, 150, 200, 260, 275, and 400 amps) are available to produce excellent cut
quality throughout the cutting range.
The same consumable are used for cutting and marking, which is determined by
selecting the desired process in the Manual Gas Console. Prior to marking, the plasma
gas and shield gas supply connections the back of the Manual Gas Console need to be
connected to nitrogen.
Each enclosure in the system is rated for IP21S sealing, which is intended for
indoor use only. The system is not suitable for use in rain or snow.
Systems containing an ASC with CleanStrike
™
Technology are only
recommended for use with downdraft cutting tables.
