Abstract

PURPOSE:To improve the transient response characteristics of a controlling system against the abrupt change of welding conditions and to stabilize the arc by detecting the presence or absence of the short circuiting between a consumable electrode and the molten part of base metals or the frequencies of said short circuiting and increasing or decreasing the welding arc output. CONSTITUTION:High frequency components of >=10Hz are waveform shaped with a filter and the change rate of average welding current with time is determined, from which the presence or absence of the short circuiting between a welding electrode and a weld zone is detected at every constant period. If the change rate of the welding current with time is small in the case of the presence of the short circuiting, the welding output voltage is increased by a constant rate, and if it is large, the voltage is increased in accordance with short circuiting times. If the change rate is small in the case of the absence of the short circuiting, the welding output voltage is increased by a constant rate and when it is large, the voltage is decreased in accordance with the change rate with time.
