You're right it probably only needs to be in the 90 to 100 degree range just to keep the moisture out. For some reason I was thinking it needed to be at the boiling point of H2O.
Quote:Welding electrodes are manufactured to have a specific range of moisture content. For example, low-hydrogen rods have a moisture content of approximately 0.1 – 0.4 percent. Cellulosic rods on the other hand have a moisture content of 4 to 6 percent. If these two types of electrodes are stored in the same oven, the lower moisture content low-hydrogen rods will absorb moisture from the higher moisture content cellulosic rods. It is important to note that cellulosic rods are not to be stored long term in a rod oven, and are only heated at low temperatures (100-120°F) if they have been exposed to humid air for an extended period of time.
I use my rod oven for 7018 rods (low-hydrogen) only.
Cellulose rods that have been sitting out for a long time just get chucked into a small toaster oven for awhile if needed.
