摘要
Embodiments of welding systems (100) and of a welding method are disclosed. A welding system (100) includes a waveform generator (107) to generate a welding waveform with an adjustable DC offset and duty cycle. A sensor (139) of the welding system (100) senses a welding parameter at a welding electrode during a welding operation. A controller (110) of the welding system (100) is coupled to the sensor (139) and the waveform generator (107) and compares the welding parameter to a pre-defined parameter. The controller (110) adjusts at least one of the DC offset and the duty cycle of the welding waveform in response to comparing the welding parameter to the pre-defined parameter to control a stick-out distance of the electrode.
