PURPOSE:To efficiently manufacture a jig in a laser beam machining area of a laser beam machine without preparing a special arc welding machine by providing a manually operated laser beam machine which can operate a laser beam branched from a laser beam splitter. CONSTITUTION:When a work is cut with a laser beam machining head 21, the laser beam LB branched from the laser beam splitter 81 is introduced from a mounting fitting of the manually operated laser beam machine 83. Further, the laser beam arrives at a nozzle holder through a gas introducing metal fitting a water introducing metal fitting a flexible connecting tube 91, a water spraying metal fitting, a manual metal fitting, a tip metal fitting. Since a condenser lens is prepared at a nozzle holder, the laser beam LB is condensed here, a target is irradiated with the laser beam through a nozzle and, therefore, a work requiring an additional work and spot welding or cutting work to a jig for machining can be performed on or near a worktable. |
