BMaintain low voltage with a high helium content gas
CIncrease voltage and amperage with an argon-rich shielding gas mixture
DDecrease voltage and use 100 percent $$CO_{2}$$
✓ Correct answer: C. Increase voltage and amperage with an argon-rich shielding gas mixtureSpray transfer mode requires higher voltage and amperage settings combined with an argon-rich shielding gas to ensure stable arc characteristics and optimal weld quality.
