We report on soft X-ray observations of the Seyfert 1 galaxy MCG-6-30-15 with the Low and Medium Energy Concentrator Spectrometers on board BeppoSAX. The time averaged 0.1-4keV spectrum shows evidence for a complex warm absorber. K-edges of highly ionized oxygen (O VII and O VIII) can only partly describe the soft X-ray spectrum below 2keV. A spectral variability study reveales large and rapid changes in absorption at the energy of the O VIII K-edge and in the continuum shape and count rate. These fluctuations are not simply correlated.
