Lack of fusion/penetration cause by : Too large an electrode for weld preparation. Incorrect angle of electrode for weld preparation. Current too low. Travel speed too high etc

Too short an arc length will cause irregular piling of the weld metal. The ripples will be irregular in height and width.

Manual metal arc (MMA) welding, also known as shielded metal arc welding (SMAW), stick, and electric arc welding is a constant current drooping arc process.
