Abstract
Embodiments of systems and methods in pulsed arc welding. A robotic welding system, having a welding torch with a contact tip, is configured to perform the following method: (a) generate and output a series of a determined number of welding output pulses as a welding wire electrode is fed toward a workpiece; (b) stop generating welding output pulses while allowing the welding wire electrode to continue to be fed toward the workpiece in an attempt to electrically short to the workpiece; (c) attempt to confirm that the welding wire electrode has electrically shorted to the workpiece within a determined error time period; and (d) repeat steps (a) through (c) if electrical shorting of the welding wire electrode has been confirmed within the determined error time period, else, shut down the robotic welding system to avoid damaging the welding torch.
