Increasing inductance promotes which mode of metal transfer?

Increasing inductance promotes which mode of metal transfer?

• A. Short circuit transfer
• B. Globular transfer
• C. Spray
• D. Pulse

Answer: (C)

In GMAW, inductance controls how quickly the welding current can change, which shapes how metal is transferred across the arc. Increasing inductance dampens current spikes and helps maintain a stable arc at higher currents. That stability and higher current level promote the formation of many small droplets that are sprayed across the arc, known as spray transfer. Lower inductance tends to allow sharp current surges and fluctuations that favor larger droplets or short-circuit transfer, so spray is less likely.
