7.2.1 Compressed air for plasma and cooling gas.
EN - 18
NOTE
• The lower the pilot current, the higher the service life of the electrode and
cutting nozzle.
• Makes sure that the connections are properly assigned and tightened.
• Since the plasma nozzle cannot be protected against direct contact for
technical reasons, it is necessary for the plasma cutting power source to
satisfy the requirements of EN 60974-7, Item 7.4.2.
• The plasma-cutting torch in connection with the plasma power source
must conform to EN 60974-10.
• The plasma power source must also be conform to EN 60974-1.
• The type of ignition (contact or HF) and the output power (rated current
and corresponding duty cycle) of the plasma power source and of the
cutting torch must be identical.

NOTE
• Precise adjustment of the compressed air pressure and flow/volume are
important for: igniting the pilot arc, quality of cut, service life of torch and
wear parts.
• An inlet pressure (p) smaller than specified results in thermal overload.
The correct torch inlet pressure must be ensured by proper adjustment of
the pressure monitor on the system side.
