ABSTRACT:
A method of AC welding that includes the step of supplying AC current with a given waveform from a power source to an advancing electrode and workpiece. The AC current is used to melt the electrode and to thereby deposit metal from the electrode onto the workpiece. The electrode includes a particulate arc stabilizing compound. The particulate arc stabilizing compound includes sodium and titanium dioxide. The particulate arc stabilizing compound constitutes over 20% by weight of the core of the electrode.
