Which statement best describes the storage requirement for low-hydrogen electrodes?

• A. Stored at 120 C
• B. Stored at room temperature
• C. Stored at -20 C
• D. Stored at 200 C

Answer: (A)

Low-hydrogen electrodes are moisture sensitive, so keeping them dry is crucial to maintain their low hydrogen content and prevent hydrogen cracking in welds. Storing them in a dry, heated environment around 120°C (about 250°F) helps minimize moisture uptake from the air. If they sit at room temperature, they can absorb moisture and lose their low-hydrogen properties. Storing at much lower or much higher temperatures isn’t standard practice and can be impractical or potentially harmful to the coating. Therefore, storing at about 120°C is the best approach to preserve their performance.
