Abstract: Provided is a system for providing pulsed arc starting phase, where the system comprises power conversion circuitry configured to convert input power to welding-type power and output the welding-type power, and control circuitry configured to control the power conversion circuitry to output the welding-type power. The control circuitry is configured to control the power conversion circuitry to output a plurality of welding current pulses during at least a portion of one or both of a run-in period or a ramp period for wire feeding of a welding wire ends, where each of the plurality of welding current pulses is associated with a respective pulse period and a respective pulse duty cycle.

Abstract: A method and apparatus for short circuit welding is disclosed. They reduce the current prior to the short clearing by adjusting waveform parameters in response to past cycles. One or more parameter of the output is monitored and compared to one or more targets, and future waveform parameters are adjusted so that the monitored parameters are more likely to reach the one or more targets.

Abstract: A pulsed welding regime includes a peak phase in which energy is added to an electrode and a weld puddle, and a molten ball begins to detach from the electrode, followed by a dabbing phase in which current is significantly reduced to place the ball in the weld puddle with addition of little or no energy. The resulting short circuit clears and the system proceeds to a background phase. The current in the dabbing phase is lower than the current during the background phase. The process may be specifically adapted for particular welding wires, and may be particularly well suited for use with cored wires. The dabbing phase allows for lower energy to be transferred to the sheath of such wires, and resets the arc length after each pulse cycle.

Abstract: A controller for a welding system adapted to determine a value of a weld secondary parameter across a weld secondary component based on a sensed parameter is provided. The controller may also be adapted to compare the determined value to a reference value range and to alert a user to a presence and location of a weld secondary error when the determined value is outside the referenced value range.
