Air Plasma Cutting

Air Plasma Cutting Advantages

• 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
