ABSTRACT:
An arc welding apparatus for pulsed arc welding includes a silicon controlled rectifier and an uncontrolled rectifier the D.C. outputs of which are connected in parallel to a non-consumable electrode and a workpiece, respectively. The silicon controlled rectifier delivers a background welding current to the arc between the electrode and the workpiece. The D.C. outputs of the uncontrolled rectifier are connected in series with transistors controlled by signals to regulate the flow of current supplied from this rectifier to the arc to provide periodically recurring welding current pulses of predetermined length and amplitude to the arc in addition to the background welding current delivered by the silicon controlled rectifier.
