Abstract

PURPOSE: To provide a titled device which maintains a good spray migration state of globules at all times at a desired wire feed speed by providing means of setting the pulse width and peak value of pulselike current at the optimum values having beforehand determined the conditions of materials of a wire, and the like.
CONSTITUTION: This pluse arc welding device is constituted of a DC power source 1, a switching circuit 2 which produces a pulselike current waveform by turning the current supplied from the power source 1 on and off an arc load 3, an arc maintaining power source 4 and a control device 5. This device 5 controls the circuit 2 thereby controlling the pulselike current to the values having preset its pulse frequency and pulse width. When this welding device is used, the quantity of heat input to a wire per pulse is made always an optimum value so as to maintain the state of spray migration at all times even when the material of the wire, its diameter, the feed speed of the wire, and the kind of shielding gas are combined as desired.
