  Quasars are notable for the luminous power they emit across decades in
frequency from the far-infrared through hard X-rays; emission at different
frequencies emerges from physical scales ranging from AUs to parsecs. Each
wavelength regime thus offers a different line of sight into the central engine
and a separate probe of outflowing material. Therefore, obtaining a complete
accounting of the physical characteristics and kinetic power of quasar winds
requires a panchromatic approach. X-ray and infrared studies are particularly
powerful for covering the range of interesting physical scales and ionization
states of the outflow. We present a stratified wind picture based on a
synthesis of multiwavelength research programs designed to constrain the nature
of mass ejection from radio-quiet quasars. This wind comprises three zones: the
highly ionized shielding gas, the UV broad absorption line wind, and the cold
dusty outflow. The primary launching mechanism for the wind likely varies in
each zone. While radiative acceleration on resonance lines dominates for the UV
absorbing wind, the shielding gas may instead be driven by magnetic forces.
Ultraviolet continuum radiative pressure, perhaps coupled with magnetic
launching, accelerates a dusty outflow that obscures the inner broad line
region in unification schemes.
