What is the minimum storage temperature for all low hydrogen electrodes in the oven?

• A. At least 110 C
• B. At least 150 C
• C. At least 120 C
• D. At least 100 C

Answer: (C)

Low-hydrogen electrodes must stay dry to prevent hydrogen from entering the weld metal, which can cause hydrogen-induced cracking. Keeping them in a heated oven prevents moisture from being absorbed by the coating during storage. The minimum storage temperature is 120 C (about 250 F), which is enough to drive off surface moisture and keep the coating dry between uses. Storing at 100 C or 110 C would be below the required level and risk moisture uptake, while 150 C is higher than necessary for storage but not harmful.
