Default Snap!

Cavalry, I believe the Miller Diversion 180 has HF arc start. I think that the snap you're hearing is the pulse of high frequency establishing the TIG arc.

Being an old guy, I can't really hear a very sharp snap in that video but it may just be the way the audio system in my Dell desktop rolls off high frequencies.
