What is a significant concern when using PAC equipment?

When using Plasma Arc Cutting (PAC) equipment, a significant concern is the moisture entering the unit through the air line. PAC systems rely on a stable supply of dry air, typically compressed, to create the plasma arc necessary for cutting. If moisture infiltrates the air line, it can lead to various problems such as inconsistent arc stability, increased likelihood of oxidation on the cut edges, and potential damage to the equipment itself.

Moisture can cause the plasma to cool erratically, leading to poor cutting performance and potentially compromising the quality of the cut. Furthermore, moisture can also contribute to corrosion inside the PAC equipment, ultimately affecting its longevity and reliability. Ensuring that the air supply is free from moisture is therefore vital for maintaining optimal PAC performance and achieving high-quality cuts.
