IF I want to just limit current from a power supply, but not change the voltage, how would I go about to achieve this? The manual that suggest that current should not exceed a certain amount of amps, suggest using "current resistors" I though resistors also lowered voltage.

Yes, if any current is flowing, then the voltage drops.
This is Ohms law, a basic physics fact. You need to go
to something with active circuitry if it is to limit current,
but NOT drop the voltage until the limit current is
reached.
