What is the amperage range for an E6010 (E4310) for the overhead 45 position?

• A. 75 - 125 amps
• B. 50 - 100 amps
• C. 25 - 75 amps
• D. 125 - 175 amps

Answer: (A)

Overhead work requires enough heat to maintain a stable arc and control the molten pool as gravity pulls it away from the joint. E6010 is a deep-penetrating, easy-arc electrode that performs well in difficult positions, but the amperage must be set high enough to sustain that arc without drifting or poor fusion. For typical small to medium diameters used in overhead 45-degree work, the common range is around 75 to 125 amps. This provides sufficient heat for proper fusion and a controllable bead in that position. Setting amperage below 75 amps tends to produce a weak arc and inadequate fusion in overhead, while going above about 125 amps can cause excessive penetration, arc blow, or rough bead control.
