THE METHOD OF ARC WELDING WORK WHICH COMPRISES MAINTAINING THE ARC CURRENT AND THE ARC VOLTAGE AT PREDETERMINED MAGNITUDES TO PRODUCE THE WELD, AS THE END OF THE WELD APPROACHES CAUSING THE ARC CURRENT TO BE REDUCED AT A PREDETERMINED RATE TO A PREDETERMINED MAGNITUDE, WHILE SAID CURRENT IS BEING REDUCED TO SAID MAGNITUDE REDUCING SAID ARE VOLTAGE, THEREAFTER REDUCING SAID ARC CURRENT WHILE SAID ARC VOLTAGE REMAINS REDUCED, AND THEN SIMULTANEOUSLY REDUCING BOTH SAID ARC CURRENT AND SAID ARC VOLTAGE TO ZERO.
