Abstract

PURPOSE:To obtain optimum pulse waveforms through regulation of average welding current, to transfer globules smoothly and to stabilize the arc by making peak current, peak current time and base current constant and changing base current time. CONSTITUTION:The current change range IP-IB between peak current IP and base current IB is set at >=300A, and since the peak current IP is required to be about >=350A, 4ms is required for peak current time TP of this time in consideration for wire diameters and wire materials. Since the max. value of the peak current is about 800A, the peak current time TP of this time is 0.2ms, and the time T since the start of rise of th peak current IP until the start of its fall is 0.2ms<=T<=4ms. In a spray region, the value of the base current IB is changed over to the larger value, average current value Im is increased and the base current time TB is made long, whereby arc sounds are reduced.
