Pulses per second (PPS) in GTAW-P describes how many times the welding current peaks per second.

Explanation:
In GTAW in pulsed mode, the current rises to a peak and then drops to a lower level repeatedly. Pulses per second is a frequency measure that counts how many times per second the current reaches that peak. So PPS directly describes the rate of peaks occurring each second. It’s about how often the peaks happen, not how high the peak is or how long each pulse lasts—that’s set by the peak current and the pulse duration/duty cycle. Therefore, the statement is true.
