In this paper, we study a spacelike (timelike) ruled W-surface in Minkowski 3-space which satisfies nontrivial relation between elements of the set ${K, K_{I I}, H, H_{I I}}$ , where $(K, H)$ and $(K_{I I}, H_{I I})$ are the Gaussian and mean curvatures of the first and second fundamental forms, respectively. Finally, some examples are constructed and plotted.
