Question: When welding with an E6010 electrode, a welder observes a very 'digging' arc, excessive spatter, and undercutting along the weld toes. What is the most likely cause of these issues?
Answer options:
- Insufficient amperage
- Excessive arc length
- Reverse polarity (DCEP) instead of straight polarity (DCEN) ✅ Amperage setting is too high
Correct answer: Amperage setting is too high
Explanation: A 'digging' arc, excessive spatter, and undercutting are classic symptoms of an amperage setting that is too high for the electrode and material. Straight polarity (DCEN) would result in less penetration and a cooler arc, not the issues described.
