Question

what type of current is used for pac? ac or dc?

ac
dc

Explanation:

Identify the process requirements

Plasma Arc Cutting (PAC) requires a stable, continuous, and highly concentrated electric arc between the electrode (cathode) and the workpiece (anode) to ionize the gas into plasma.

Determine the appropriate current type

Direct Current (DC), specifically Direct Current Electrode Negative (DCEN), provides the stable arc and concentrated heat at the workpiece necessary for efficient cutting, whereas Alternating Current (AC) would constantly extinguish and reignite the arc.

Answer:

• AC
• DC (Correct answer)
