GAS-OXYGEN CUTTING TIP

摘要

The present invention relates to a gas-oxygen cutting tip to cut a vertical member. According to the present invention, a tip (100) for a cutter to cut a steel material comprises: a cutting oxygen injection device (200) to discharge oxygen gas to a lower part of a center of the tip (100); a pre-heating fuel intake (300) formed by a plurality of grooves, at equal intervals radially outwards the cutting oxygen injection device (200); and a body (400) in a form of an arc covering the pre-heating fuel intake (300), whose lower part in contact with a cutting base material has a circular arc greater than an upper circular arc. The present invention has an effect of minimizing the generation of residues and damage to a workpiece by mounting and fixating a tip (100) on a vertical structure of the workpiece to be cut by forming the tip (100) in the form of an arc.
