7 Operation
NOTICE
• The lower the pilot current, the longer the service life of the electrode and the cutting
nozzle.
• Make sure that the connections are properly assigned and tightened.
• Since the plasma nozzle cannot be protected against direct contact for technical reasons,
the plasma cutting power source must fulfil the requirements of EN 60974-7, point 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 conform to EN 60974-1.
• The plasma power source and cutting torch must have the same type of ignition (contact
or HF) and the same output power (rated current and corresponding duty cycle).

7.2.1 Compressed air as plasma and cooling gas
NOTICE
• Precisely setting the compressed air pressure and flow/volume is important for the pilot
arc ignition, cut quality and service life of the torch and wear parts.
• An inlet pressure (p) smaller than specified results in thermal overload. The correct torch
pressure must be ensured by properly setting the pressure monitor on the power source.

7.2.2 Filtered compressed air free from oil and water
NOTICE
• Use only compressed air which is free from dirt, oil and water.
• We recommend:
• Initial filter with a 5 µm pore size
• Sub-micro filter with a 0.01 µm pore size
• 99.99% oil separation rate
• Air throughput at a flow pressure of 5.0 bar:
