Which wire diameter is outside the range 0.023 to 1/16 inch?

• A. 0.012 inch
• B. 0.023 inch
• C. 0.030 inch
• D. 0.040 inch

Answer: (A)

Wire diameter must fit within the specified size range for reliable feeding and welding performance. Here, the acceptable range is from 0.023 inch up to 1/16 inch (0.0625 inch). A diameter smaller than the minimum is outside the range, so 0.012 inch doesn’t fit. The other options are at or between the limits: 0.023 inch is the lower boundary, and 0.030 and 0.040 inches fall between 0.023 and 0.0625. Therefore, 0.012 inch is outside.
