What is the purpose of using a filter/dryer in a PAC system?

The use of a filter/dryer in a Plasma Arc Cutting (PAC) system is crucial for ensuring the quality and reliability of the plasma cutting operation. Its primary purpose is to remove moisture and contaminants from the air supply.

When compressed air is used in PAC systems, any moisture present can negatively affect the quality of the plasma arc, leading to inconsistent cuts and potential damage to the equipment. Moisture can cause oxidation and rusting within the system, which compromises the integrity of the components and may lead to increased maintenance costs or system failures.

Additionally, contaminants such as dirt, dust, and oil particles can also hinder the performance of the plasma cutting torch. These impurities can interfere with the plasma arc itself, reducing cutting efficiency and precision. By ensuring that the air used in the PAC system is clean and dry, the filter/dryer maintains proper operation and output quality, ultimately increasing productivity and extending the lifespan of the equipment.

The other options do not accurately represent the primary function of a filter/dryer in this context. Cooling the air, increasing pressure, and regulating electric current do not pertain to the main objectives of moisture and contaminant removal, which is why those choices do not capture the essence of the filter/dryer's role within a PAC
