What is the requirement for compressed air used in the PAC process?

• A. Partially dry
• B. Completely dry
• C. Filtered
• D. Oxygen-enriched

Answer: (B)

In the Plasma Arc Cutting (PAC) process, the requirement for compressed air is that it needs to be completely dry. Moisture in the compressed air can adversely affect the plasma arc stability and quality of the cut. If water vapor is present, it can lead to inconsistent cutting, increased oxidation of materials during the process, and potential equipment damage due to moisture interfering with electrical components. The plasma cutting process relies on a finely controlled arc, and the presence of moisture would disrupt the ionization needed for a stable arc. Therefore, using completely dry air ensures optimal performance and longevity of the equipment while achieving high-quality cuts on various materials. This requirement emphasizes the importance of keeping the compressed air free from water, as even small amounts can result in significant inefficiencies during cutting operations.
