摘要: An improvement in a short circuiting arc welding apparatus of the type including power supply for causing current different levels to pass through wire extending at variable extension distances from holder and between workpiece molten metal pool on workpiece. This includes control means maintaining generally constant wattage during plasma boost portion arcing condition as distance changes. Further, involves controlling or after by curve gradually decreasing toward background level system.
