Examine the gas supply
Examine the whole gas supply line. Are there any signs of contamination, such as from oil,
water, or dirt? It is extremely important to keep a clean, dry gas line. Refer to
page 126 .
Is your air filtration system sufficient to prevent moisture, oil, and other contaminants from getting into
the plasma power supply’s gas line? Refer to
page 126 . Add additional filtration if necessary. Refer to
page 60 .
Is the gas supply hose connected correctly to the fitting on the rear panel of the plasma power
supply?
Is the gas supply hose connected correctly to the air compressor, gas cylinder, or other gas source?
Does the gas supply hose have a minimum internal diameter that is sufficient? Use an internal
diameter of 10 mm (3/8 inch) for hoses that are less than 15 m (50 feet). Use an internal diameter of
13 mm (1/2 inch) for hoses that are 15 m – 30 m (50 feet – 100 feet).
Is sufficient gas pressure getting to the plasma power supply? Refer to page 125 .
Are you able to keep gas pressure constant while you are cutting? Do a gas test to see if the plasma
power supply’s actual output gas pressure is lower than the set pressure by more than an acceptable
quantity. The set pressure is the gas pressure that the system sets to align with the type of cartridge
and torch installed. Refer to
page 147 .
Is there anything that can be causing the pressure to decrease too much while cutting? For example,
is the gas supply hose too long? Are there other devices that use gas from the same source?
Examine the gas supply hose. Is it twisted or kinked? Are there any other signs of damage to the
hose?
Examine each fitting and connection point in the gas supply line. Are there any signs of leaks?
Examine the filter element in the plasma power supply’s built-in air filter. Is it contaminated? To
replace it, refer to
page 171 .
