Abstract
PURPOSE: To reduce the production of fumes by using the intermittent arcs obtainable from a pulse power source of the specific pulse number or a high-frequency power source and performing working while moving the arc pole point at a high speed at the time of generating arcs between carbon electrode and base metal and arc air working.
CONSTITUTION: At the time of performing arc air working by generating arcs between carbon electrode and base metal and flying molten metal by compressed air, a pulse power source of the pulse number exceeding twice the commercial frequency or a high-frequency power source exceeding the commercial frequency is used and the intermittent arcs obtainable from these are used. At this time, arrangement is so made that the arc pole point B stays for 1/300W1/200 second or under at one point in the molten pool of the base metal. In the state where the arc voltage is high, the arc column (arc pass) C elongates long and the arc pole point B is formed in the portion of the front slag D, thus the production amount of fumes (E) is reduced.
