2 – Power Supply Setup
Prepare the gas supply
The gas supply can be shop-compressed or cylinder-compressed. You must use a high-pressure regulator on either type
of supply, and the regulator must deliver gas to the filter on the power supply at 99.1 l/min at 4.7 bar (3.5 scfm at 68 psi).
To ensure adequate pressure to the power supply, set the regulator between 5.5 and 6.9 bar (80 and 100 psi).
The system contains an internal filter element, but additional filtration may be required depending on the quality of the gas
supply. If gas supply quality is poor, cut speeds decrease, cut quality deteriorates, cutting thickness capability decreases,
and the life of the consumables shortens. For optimal performance, the gas should have a maximum:
 Particle size of 0.1 micron at a maximum concentration of 0.1 mg/m 3
 Dew point of -40° C (-40° F)
 Oil concentration of 0.1 mg/m 3 (per ISO 8573-1 Class 1.2.2)
Connect the gas supply
Connect the gas supply to the power supply using an inert gas hose with a 6.3 mm (1/4 inch) or greater internal diameter
and an industrial interchange quick-disconnect coupler (for CSA models) or a G-1/4 BSPP threaded coupling (for CE
and CCC models).
CAUTION!
Some air compressors use synthetic lubricants containing esters that damage the polycarbonates
used in the air filter bowl.
The recommended inlet pressure while gas is flowing is
5.5 – 6.9 bar (80 – 100 psi).
