Plasma Arc Cutting (PAC)
Plasma Arc Cutting (PAC)
- Plasma is a state of matter; most common in solid, liquid, and gas.
- Plasma is an ionized super-heated gas that is used to cut metal through a constricting nozzle
- A constricting nozzle is the part of the PAC gun that accelerates and concentrates the arc and plasma in order to make a cutting jet
- Plasma Gas is always used in PAC
- A second gas may be use as shielding gas (shielding gas can be nitrogen, carbon dioxide, argon, argon and hydrogen, oxygen, or air
- When shielding gas is used the process is called Dual Flow Plasma Arc Cutting
- Temperature of PAC can range between 18,000 degrees Fahrenheit and 25,000 degrees Fahrenheit
Advantages of PAC
- PAC has the ability to cut all metals
- Cutting speeds are faster than oxyfuel cutting
- No preheating is required
- Distortion and heat defects on the metal are minimized
- No hazardous or explosive gases are used
Disadvantages of PAC
- PAC equipment can cost more than other processes
- Source of electricity is required
- Presence of an arc can cause safety hazards
