Examine the gas supply
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?
Examine each fitting and connection point in the gas supply line. Are there any signs of leaks?
Is the gas supply hose twisted or kinked? Are there any other signs of damage to the hose?
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?
Is sufficient gas pressure getting to the plasma power supply? Refer to page 23.
Are you able to keep gas pressure constant while you are cutting? Refer to page 23.
Examine the gas quality
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 24.
Is your air filtration system sufficient to prevent moisture, oil, and other contaminants from getting into
the plasma power supply’s gas line? Add additional filtration if necessary. Refer to the
Powermax65/85/105 SYNC Operator Manual (810470) for more information.
Examine the filter element in the plasma power supply’s built-in air filter. Is it contaminated? To
replace it, refer to the Powermax65/85/105 SYNC Operator Manual (810470).
