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.

Abstract: Welding power is generated by first generating two different current waveforms, and comparing the waveform values for control intervals to select which waveform provides the greater current. The waveforms are for different transfer modes, such as one for a pulsed arc portion, and another for a short-circuit transfer mode or for short-circuit clearing. The waveforms may be programmed by settings in a state machine. A balance or relative prioritization in the comparison may be influenced by user inputs. The resulting hybrid process has aspects of both spray transfer and short-circuit transfer modes.

Abstract translation: 通过首先产生两个不同的电流波形并比较控制间隔的波形值来选择哪个波形提供更大的电流来产生焊接功率。 这些波形用于不同的传输模式，例如用于脉冲弧部分的传输模式，另一种用于短路传输模式或用于短路清除。 波形可以通过状态机中的设置进行编程。 比较中的平衡或相对优先级可能受用户输入的影响。 所产生的混合过程具有喷射转移和短路转移模式的方面。
