ABSTRACT:
A method and apparatus for flame-cutting segments from angle irons. The apparatus supports a torch for movement across the surface of an angle iron, the corner of which is directed upwardly. The torch moves horizontally and upwardly as it cuts the first leg and horizontally and downwardly as it cuts the second leg. The torch tip is directed at a constant 45.degree. angle to the surface of the angle iron and maintained at a constant distance therefrom and moves at a constant pre-set speed throughout any one cutting operation.
