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.
