What is the result of inadequate air pressure in Plasma Arc Cutting (PAC)?

Increased Efficiency
Decreased Cutting Speed
Carbon Deposits
Improved Accuracy

The correct answer is: Carbon Deposits

When there is inadequate air pressure in PAC, it will result in the formation of carbon deposits on the surface being cut. This is due to the incomplete combustion of the plasma gas, which leads to the deposition of carbon particles on the workpiece. This can negatively affect the quality of the cut and may even damage the equipment. As for the other options, increased efficiency and improved accuracy are not results of inadequate air pressure, but rather, they are benefits of having proper air pressure. Decreased cutting speed may occur if there is too much air pressure, but it is not a result of inadequate pressure.
