Abstract: A method of preventing arc flaring events for a welding system is provided. The method includes determining, by a controller, a real-time welding output characteristic of the welding system. The method additionally includes comparing, by the controller, the real-time welding output characteristic to a threshold welding output characteristic. The method further includes controlling an operating characteristic of the welding system in response to a determination that the real-time welding output characteristic exceeds the threshold welding output characteristic.

Abstract: The invention described herein generally pertains to a system and method related to reducing magnetic arc blow during a welding operation performed by a welding system. In accordance with one embodiment of the invention, a welding system including a waveform generator generates a waveform that is switched from a positive current to a negative current, while passing through zero, in a step-wise fashion to resist the magnetic field within the material (e.g., the workpiece). In accordance of another embodiment of the invention, the welding system includes a nickel flux cord welding wire.

Abstract: Systems and methods for facilitating the starting and stopping of arc welding processes, as well as for responding to events in mid-weld. Specially designed signals may be briefly applied between a welding electrode and a welding workpiece at the start and end of a welding process to gracefully and properly start and stop a weld. Furthermore, specially designed signals may be briefly applied in the middle of a welding process, if determined events occur, to counter the undesirable effects of the events.

Abstract: Systems and methods to affect heat input to a weld and, therefore, an appearance of a deposited weld bead by modulating a mixing ratio of shielding gases and/or one or more welding parameters. For example, a mixing ratio of two different shielding gases from two sources of shielding gases may be modulated to affect the appearance of a deposited weld bead. The modulation frequency may be based on a selected travel speed of a welding tool. Furthermore, a wire feed speed of a welding electrode may be synergistically modulated with the shielding gases to affect a deposited weld bead appearance. Other welding parameters may be synergistically modulated with the shielding gases to affect a deposited weld bead appearance.
