Yes, AFAIK all Atari games (at least from that era) have swithable power supply's with the different pigtail.
I have converted an upright and a cockpit from 110V to 230V by changing the pig-tail wiring.
Note that in that case you have to clearly mark it because maybe someone in the future will read the manual, see the wire colors and assume the wrong voltage is set-up.
Not sure which way you want to go, but if you are in a 230V country I would set it up for 240V (not 220V). My experience is that mains voltage is usually a bit higher than 230V and almost never lower. 220V will work, but 240V lessons the "tension" on the PSU.
