Claims9
An arc welding system, comprising:
- a welding gun including a contact tip having a channel and an exit orifice;
- an arc welding power supply which provides an arc welding waveform to at least two arc welding consumable electrodes having a circular cross-section via said contact tip;
- and
- a wire feeding mechanism which provides said at least two arc welding consumable electrodes from respective electrode sources to said channel in said contact tip, where said arc welding electrodes pass through said channel in a longitudinal orientation without intertwining or twisting with each other and exit said contact tip through said exit orifice.
