Awl--

In a previous thread it was mentioned that some cellulose rods should not be kept in an oven, because they need moisture, while others should. How does one know which rods should be kept in an oven? In particular, which rods should? And, for those rods, how much does the oven help in welding ease/quality?

Any recs? Variable thermostat a good idea? I got 600 W laboratory "hot plates" with a heat control. Does it make sense to make my own oven?

My understanding is that only low hydrogen rods need to be kept in an oven and any rod with cellulose in the flux will be better with some humidity. And most home built ovens are no where near hot enough. My memory says low hydrogen rods as 7018 need an oven at 250 degrees F or about 120 degrees C. And keeping them in an oven does not help welding ease. It keeps them dry so no hydrogen disolves into the metal. If you are welding things that don't need low hydrogen then the oven does not matter.

A slightly heated oven might be useful to keep rods from rusting.

Hi, i cant comment on what types of rods need to be kept in an oven and which dont; at most places ive worked all rods were kept in an oven, though most work was low hydrogen. how much you benefit depends on your climate. if its humid, you will notice a considerable benefit from cooking your rods before use. many bigger campanies have a hot room for storing rods rather than an oven... just a big walk in steel locker with a heating globe in it to keep the room nice and dry.
