Abstract
A welding or additive manufacturing system includes a power supply having a controller which controls operation of the power supply. The power supply provides a current waveform to a contact tip assembly having a first bore terminating at a first exit orifice and a second bore terminating at a second exit orifice. The first exit orifice is configured to deliver a first wire electrode and said second exit orifice is configured to deliver a second wire electrode. The exit orifices are separated from each other by a distance configured to facilitate formation of a bridge droplet between the wire electrodes while preventing solid portions of the first wire electrode delivered through the first bore from contacting solid portions of the second wire electrode delivered through the second bore, during a deposition operation in which the current waveform is conducted to both of the wire electrodes simultaneously through the contact tip assembly.
