  CNC-PLASMA
  FINE FOCUS 450

Plasma cutting unit preferred for CNC
     controlled cutting of all electrically
     conductive materials with guiding
     machine or robot. Cutting range up
     to 45 mm material thickness
     (material depending), quality cut
     up to 25 mm thickness, piercing by
     arc voltage controlled height sensing
     system up to 25 mm and stationary up
      to 12 mm.

 Excellent cutting quality and longevity
     of cutting nozzles by swirl-gas
      technology.

Metallic clean cutting surfaces, cuts
     free or nearly free of dross and
     cutting results aftertreatment-free
     by pre-selection of the suitable
     plasma gas mixture: Air, O2,
     Ar/H2/N2, Ar/H2, Ar/N2).

 Small kerfs, minimal material
     loss and therefore low pollution
      by FineFocus principle.

 XL-Life-Time-system for metallurgical
     perfect cutting of mild steel, no
     aftertreatment necessary if welding
     follows.

 High reliability of plasma torches
     by direct     and higheffective cooling
     of plasma torch.

. Stepless adjustable cutting current between 40 and 130 A
  (100 A at 100 % duty cycle).

. Excellent cutting properties by smooth current due to
  12-pulse bridge circuit.

. Contactless high-voltage ignition of pilot arc.

. Pre-set control of cutting current and digital display
  of cutting current and cutting voltage.

. Select-control of cutting current by potentiometer,
  remote control or CNC control (guidance system,
  robot or direct control).

. Direct pre-selection of plasma gases or plasma
  gas mixtures (Air, Air, O2, Ar/H2/N2, Ar/H2, Ar/N2).

. User-friendly and extensive diagnostics and service
  system for control of the most important operating
  states by LED-displays

. Excellent suitability for industrial use for CNC-controlled
  cutting tasks.

. Fulfils safety requirements of EN 60974-1,
  EN 50078 and EN 50192.
