What can cause excessive spatter and undercut of weld bean?

  1. Low current

  2. Correct current

  3. High current

  4. No current

The correct answer is: High current

Excessive spatter and undercut of weld bead can be caused by high current. This is because high current results in an excessive amount of heat being applied to the metal, leading to increased spatter and undercutting of the weld bead. Options A, B, and D are incorrect because low current, correct current, and no current would not generate enough heat to cause excessive spatter and undercut.
