Abstract

PURPOSE: To perform even welding by using the power source which combines the approximately constant current characteristics of small fluctuations in the output current voltage of the power source in a transient state and the approximately constant voltage characteristics and further change to approximately constant voltage characteristics of a short time until a steady state is reached in the neighborhood of the operating point in a steady state.
CONSTITUTION: A consumable electrode is fed at approximately a constant speed and a power source having the non-linear characteristics wherein the output voltage and current characteristics of the welding power source near the operating point change from approximately constant current characteristics to approximately constant current characteristics is used, so that the operating point in a steady state during welding is held let to exist on the approximately constant voltage characteristics and the operating point having moved depending upon the fluctuations in the arc length or arc voltage during welding is moved along the specified characteristic curves and is converged at the balance point. For example, when the operating point moves to P51 upon changing of the arc length owing to disturbance, the operating point moves in the direction of PS-5 on the curve running the point P51 and moves downward on the curve PS-5 from the point P511 and converges at the operation point P50 of a steady state.
