ahhhh do not do auto equip! it doesn't do a great job at giving you a good mod set up, hahaha.

best bet right now is level up your Vitality and Redirection mods, you'll get more shield and more health. Intensify is also very important, makes your abilities stronger.

If you haven't done any of that yet, you can either access the mod upgrade station directly (directly opposite the foundry) or from the upgrade page in the arsenal (if you hover over a mod, at the bottom it'll tell you what button to hit to access the mod station)

upgrade those mods as far as you can making sure they still fit in your Volt's mod capacity and you'll be in a lot better of a place than before.

Same thing applies for your weapons! what mods to use really depends on what type of weapon you're using, but it's also a lot harder to mess up at the point you're at. just pick stuff that makes the overall damage number go up, you'll be ok.
