ABSTRACT:
In making sheet metal parts by means of oxygen cutting, the cutting torch is positioned so as to direct the oxygen jet at an angle of 4.degree.-5.degree. from the vertical in the direction of the cut and at an equal angle toward the part being cut out. An arrangement for orientating the gas cutting torch comprises two coaxial cylinders. The outer cylinder is mounted rotatably in relation to the inner cylinder. The inner cylinder is fixedly mounted on the carriage of the gas cutting machine and is connected through a flexible means to the cutting torch which is fitted in a bearing whose outer race is linked to the outer cylinder and is adapted to have an angular motion in a vertical plane. Gas supply hoses pass through the inner cylinder to the cutting torch.
