Voltage is typically 4-15v, with 7-10v being the most common. Increasing DC voltage increases the electrochemical activity. At too high a voltage (the spark over point) electrical arcing will occur and the process becomes EDM. This is never recommended. Voltage selection is sometimes material dependent, e.g. copper may require a longer voltage because it is highly conductive, but mostly voltage is adjusted to optimize other cutting parameters.
