WELD-301C Practice Test

In wire welding, how the molten filler metal travels across the arc defines the transfer mode. The recognized main modes are short circuit transfer, globular transfer, and spray transfer. There’s also a pulsed variant of spray transfer, which uses a timed current to control droplet formation. The term pulsed by itself isn’t considered a separate main transfer mode; it describes a method used to achieve spray transfer rather than a distinct category. So, the option described as pulsed is not a main transfer mode, even though it can be used to produce spray transfer.
