ABIPLAS CUT HF
7.2 Connecting the plasma cutting torch
Requirements for connecting the torch
1 Only use compressed air which is free from dirt, oil and water.
2 Ensure that the connections are properly assigned and tightened.
3 Ensure that the correct air pressure (flow pressure) and correct air volume are set. Insufficient
air volumes can lead to the torch overheating.
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.
• When used with the plasma power source, the plasma cutting torch 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 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.
