Which of the following is NOT a main transfer mode for wire welding?

• A. Short circuit
• B. Globular
• C. Spray
• D. Pulsed

Answer: (D)

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.
