Which statement correctly links DCEP to welding performance?

• A. DCEP provides better penetration
• B. DCEP provides shallower penetration
• C. DCEP reduces arc stability
• D. DCEP minimizes spatter

Answer: (A)

Direct current electrode positive polarity directs more of the arc heat into the workpiece, which promotes deeper fusion into the base metal. That increased heat at the joint leads to better penetration than when the electrode is negative, where more heat tends to stay at the electrode and penetration is shallower. So the statement linking DCEP to welding performance that best fits is that DCEP provides better penetration. The other ideas aren’t as general or reliable: arc stability and spatter depend on many factors beyond polarity, so they’re not universally guaranteed outcomes of DCEP.
