ABSTRACT:
The present invention is directed to a device for marking and/or cutting a pipe. The device includes a fixture for clamping one of the pipe fittings in a desired position relative to an axis passing through the pivot center of a projecting boom to which an effecting element is afixed in such a way to follow the outside of the wall of the pipe fitting at a present distance from the axis, preferably matching the radius of the other pipe fitting, as the projecting boom pivots about its pivot center.
