Does Saturn have a weak spot?

I understand that Saturn, being an armoured enemy, is vulnerable to corrosive attacks. However, he has a stunning amount of health and the damage he is able to kill me in one hit. I plan to level up once again before I attack him but I would like to know his weak spot so as to make him easier to kill.

I have attempted to hit the weak spot of the other bots. such as its the wires in between his armour but no avail.

Why is this so? Is it because I am hitting the wrong spot? If so, where is his weak spot?

Saturn has no crit spot. You can see this for yourself with zero's b0re skill, which highlights crit spots while you're in deception. I've personally shot him all over too. There's no crit spot on his back.
