An E6011 electrode may be used with which current polarity?

• A. DC- only
• B. AC or DC+
• C. DC+ only
• D. AC only

Answer: (B)

Polarity compatibility and arc stability for E6011. E6011 uses a cellulose-based flux that supports a stable arc across different current modes, so it can be used with alternating current or with direct current in the positive polarity. With AC, the current reversals help keep the arc stable and easy to control, while with DC+ the electrode is positive and the arc remains reliable, giving good fusion and bead quality in various positions and on marginally prepared surfaces. That versatility is what makes this electrode suitable for AC or DC+. It isn’t limited to a single polarity, which is why other polarities aren’t the best fit for the way this coating behaves.
