ABSTRACT:
This invention provides an improved method for employing a plasma-arc cutting torch to cut a metal plate. The improvement consists in operating the torch with its lower portion submerged in a layer of water provided over the workpiece. In order to allow automatic adjustment of the torch to the appropriate working height above the workpiece, a mechanism is provided for mounting the torch with respect to the support carriage which guides its horizontal path. This mounting mechanism is such as to allow relative up and down movement between the torch and the support carriage and includes a detecting mechanism including a frame and vertical slides on which the cutting torch is secured so that when the mounting mechanism is lowered to the point where the torch touches the metal plate, the detecting mechanism communicates a signal for the upward movement of the mounting mechanism thereby raising the torch to a predetermined cutting distance from the metal plate.
