Gas supply source
 Use shop-compressed gas or cylinder-compressed gas.
 Use a high-pressure regulator on either type of gas supply. The regulator must be able
to supply gas to the air inlet on the plasma power supply at the specified flow rate and
specified pressure.
 Use only clean, moisture-free gas.
 Oil, water, vapor, and other contaminants in the gas supply can cause damage to
internal components over time.
 Poor gas supply quality causes:
 Decreased cut quality and cut speeds
 Decreased cut thickness capability
 Decreased consumable life
To correct these problems, use an optional air filtration system. Refer to Add more gas
filtration on page 41.
Hypertherm recommends that air compressors supply air that meets these requirements of
ISO Standard 8573-1:2010 Class 1.4.2*:
Maximum particle count in 1.0 m
3
: • 20,000 at 0.1 microns – 0.5 microns
• 400 at 0.5 microns – 1.0 microns
• 10 at 1.0 microns – 5.0 microns
Maximum water vapor pressure dewpoint: 3°C (37°F)**
Maximum oil concentration: 0.1 mg/m
3
(for aerosol, liquid, and vapor)
* Important: Any air compressors that supply air to the cutting system must have filtration to remove oil.
** Speak to your air compressor manufacturer if you operate the cutting system in temperatures colder than 3°C (37°F)
or if you are unsure that the air compressor can comply with the ISO standard for air quality.
NOTICE
DIRTY, OILY AIR CAN CAUSE DAMAGE TO THE AIR FILTER BOWL
Synthetic lubricants that are used in some air compressors can contain esters that cause damage to
the polycarbonates in the air filter bowl. Use additional gas filtration if necessary.
