Prepare the gas supply
The gas supply can be shop-compressed or cylinder-compressed. A high-pressure regulator must
be used on either type of supply and must be capable of delivering gas to the air inlet on the power
supply.
If the 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 be compliant with ISO8573-1:2010, Class 1.2.2 (that is, it should have a maximum number
of solid particulate per m
3
of <20,000 for particle sizes in the range of 0.1-0.5 microns, <400 for
particle sizes in the range of 0.5-1 microns, and <10 for particle sizes in the range of 1-5 microns).
The maximum water vapor dew point should be <-40
°
C (-40
°
F). The maximum oil (aerosol liquid
and vapor) content should be less than 0.1 mg/m3.
Additional gas filtration
When site conditions introduce moisture, oil, or other contaminants into the gas line, use a 3-stage
coalescing filtration system, such as the Eliminizer filter kit (part number 128647) available from
Hypertherm distributors. A 3-stage filtering system works as shown below to clean contaminants
from the gas supply.

The filtering system should be installed between the gas supply and the power supply. Additional
gas filtration may increase the required minimum inlet pressure.
