Air Plasma Cutting

  • 3 to 5 times faster than conventional gas cutting
  • Can deal with any conducting material, including those not suited to normal gas cutting.
  • Stainless steels
  • Chromium-nickel alloys
  • Aluminum
  • Copper
  • Works best on ranges from .03″ to 1″
  • More efficient than other types of gas plasma
  • Can cut up to .15 m/sec continuously.

Summary of Air-Plasma characteristics

  • mechanics of material removal – melting
  • medium – plasma
  • tool – plasma jet
  • maximum temperature = 16,000C
  • maximum velocity of plasma jet = 500 m/sec
  • maximum mrr = 150 cm3/min
  • specific energy = 1000 W/cm3/min
  • power range = 2 to 200 KW
  • maximum plate thickness = 200 mm (depends on material)
  • cutting speed = 0.1 to 7.5 m/min
  • voltage 30 to 250 V
  • current <= 600 A
  • critical parameters – voltage, current, electrode gap, gas flow rate, nozzle dimensions, melting temperature
  • materials applications – all conducting materials
  • shape application – cutting plates
  • limitation – low accuracy
