During spray transfer, increasing inductance does what?

During spray transfer, increasing inductance does what?

• A. Speeds up transfer
• B. Slows down
• C. Has no effect
• D. Changes to globular

Answer: (C)

Inductance in the welding circuit mainly changes how quickly the arc current can rise and fall. That matters a lot in transfer modes with rapid current changes, like short-circuit or globular transfer, where dampening those spikes helps stabilize the arc and reduce spatter. Spray transfer, however, is a continuous, high-current process where droplets transfer in a steady, smooth manner. Its behavior is largely set by the welding voltage, wire feed speed, and shielding gas, not by how quickly the current can change. So increasing inductance doesn’t alter the spray transfer; it has no practical effect on this mode.
