Most of my welding is not stick, so my rods sit for a long time. I can't see affording to run a rod oven for years just to store them. So I played with the idea of vacuum sealing them, either in bags or heavy duty rod holders. The bag system ( like a food storage) probably doesn't create enough vacuum to remove existing moisture, but might keep good rods dry. Using a vacuum (air conditioner recharge pump) on a heavy tube container would definitely keep rods dry, although it may not be enough to suck out existing moisture. Another high vacuum source is manifold vacuum on an engine. On deceleration you can pull 29" of vac and lock the storage tube.
So I guess the question is, how dry is dry enough? Has anyone else tried vacuum storing rods between usesage? How would I know if they are dry enough? Is it overkill, should they be fine just in the sealed container, maybe a bag a of decateciant or rice thrown in? So... How dry is dry enough, especially for low hydrogen rods?
