WELDING CONTROLLER REDUCING TIME FOR RETURNING REGULARITY TO A STEADY STATE AND A CONTROLLING METHOD THEREOF

摘要

PURPOSE: A welding controller and a controlling method thereof are provided to prevent welding quality degradation even though quality of the welding is irregular.;CONSTITUTION: A welding controller comprises a volume secession detection unit and a waveform generator. The volume secession detection unit detects the secession of a volume from a metal welding wire leading end(205). The waveform generator generates a first pulse(201) and a secondary pulse(202) by turns and outputs to a power source for the electric welding. The first pulses dislodge a capacity(207). The secondary pulse standardizes the capacity. The waveform generator immediately converts a current value of the first pulses into a smaller value than the current value, if the secession of the capacity is detected.;COPYRIGHT KIPO 2010
