Which of the following best describes the polarity requirement of E6010 welding?

Explanation:
Polarity affects how heat is distributed between the workpiece and the electrode, which directly changes arc stability and penetration. E6010 uses a cellulose-based flux that produces a very penetrating, stable arc, and it is best achieved when the current has the electrode as positive (DC reverse polarity). With DC reverse polarity, more heat goes into the workpiece, giving deeper penetration and a better root pass for this electrode. Using DC straight polarity would push more heat into the electrode and reduce penetration, while AC can be used in some setups but is not the specified polarity for this electrode in standard practice. Therefore, DC reverse polarity only best describes the polarity requirement for E6010.
