Question

which one of the following plasma arc cutting (pac) parameters controls how intense the cutting arc is, which determines the thickness of the material that can be cut?
a amperage
b gas flow
c arc voltage
d cutting speed

Explanation:

Amperage controls the arc intensity in plasma arc cutting. Higher amperage increases arc energy, allowing cutting of thicker materials. Gas flow affects arc stability, arc voltage relates to arc length, and cutting speed impacts cut quality, not primary arc intensity for material thickness.

Answer:

A. amperage
