The weapon used a charge function to prepare a torrent of electricity at the target which, when fully charged, could affect up to four other targets. This type of weapon was similar to the plasma disruptors originally used by dismounted clone pilots as a personal weapon. The weapon shooting an electric shock would severely damage the wiring and systems of droid opponents. These weapons were named for their ability to "arc" from one target to another.
