Which electrode designation corresponds to roughly a 75–125 amp range in overhead 45 position?

Which electrode designation corresponds to roughly a 75–125 amp range in overhead 45 position?

• A. E6010 (E4310)
• B. E7018
• C. E309L-16
• D. E316L-16

Answer: (A)

In this context, the electrode designation tells you about how the arc behaves and what current range you’ll typically use for common rod sizes in a given position. An E6010 electrode uses a cellulose coating that creates a deep, penetrating arc and a fast-freezing puddle, which helps you control the weld pool in the overhead 45-degree position. That arc characteristics and the way it welds makes it well-suited to operating around roughly 75–125 amps for common rod sizes, so it matches the given range nicely. The other options use different coatings and alloy chemistries that generally require different current levels or are chosen for different service (for example, some are stainless or low-hydrogen types) and don’t align with this specific amperage window in overhead work.
