The real hero though is AC current, allowing the voltage to help break the arc as well.

Arc length is determined in part by voltage. DC would be constant so you'd be breaking the arc at full voltage. With AC the voltage cycles through 0 60 times a second, allowing the arc to dissipate naturally and it cannot reform because the voltage required to maintain an arc is lower than what is required to start it.

Sure but would it kill an elephant?
