BDecrease voltage while increasing wire feed speed
CIncrease voltage while decreasing wire feed speed
DDecrease both voltage and wire feed speed
✓ Correct answer: A. Increase both voltage and wire feed speedSpray transfer in GMAW requires both higher voltage and an increased wire feed speed. Increasing voltage expands the arc and supports a rapid droplet transfer, while an increased wire feed speed maintains a consistent droplet supply, collectively stabilizing the spray mode and improving weld quality.
