What weld defect is usually caused by an excessively long arc length in Shielded Metal Arc Welding (SMAW)?

Correct Incorrect A long arc length leads to an unstable arc and increased spatter from metal transfer. It may also reduce penetration, but spatter is the most noticeable defect. Keeping arc length controlled stabilizes the arc cone.
