In short-circuit transfer, the electrode touches the work and short circuits, causing the metal to transfer as a result of the short. This happens at a rate of 20 to more than 200 times per second. The advantage of the short-circuit transfer is its low energy. This method is normally used on thin material ¼ inch or … See more Globular transfer means the weld metal transfers across the arc in large droplets, usually larger than the diameter of the electrode being used. This mode of transfer generally is … See more In the pulse-spray transfer mode, the power supply cycles between a high spray transfer current and a low background current.
