Abstract

PURPOSE: To lead the main arc to right under electrode with a pilot arc of high stiffness by making the current value of the pilot arc between series arc generating threshold current value and operating current value.
CONSTITUTION: The current value of a pilot arc is set between series arc generating threshold current value and operating current value. Taking this range obviates the occurrence of series arc, makes current density maximum and enables the extremely stiff pilot arc to be obtained. Thereby, the main arc may be led to right under electrode and even immediate after arc starting, sound weld beads may be obtained.
