摘要
The invention described herein generally relates to a system and method for generating a negative polarity welding output current waveform to control a welding process. The electric arc welding system produces an electric welding waveform with negative polarity portions. The cycle of the electric welding waveform includes a background current phase, a short clearing ramp phase after the background current phase, a peak current phase, and a tail-out current phase of the electric welding waveform, the peak current phase giving a negative peak current level, The tailout current phase provides a monotonically increasing tailout current level towards the positive background current level, and the short clearing ramp phase provides a decreasing current level of both polarity currents for the electric welding waveform.
