Hello all. A few months ago I picked up a welding rod oven with a bunch of different rods at an auction and I'm wondering what y'all think would be the least expensive way to keep the rods dry. Seeing as how I live in the PNW, and more specifically on the Wet side of the mountains, there's a significant amount of ambient moisture in the atmosphere. I weld only on occasion, so I'm having a hard time justifying keeping the oven on all the time, and am thinking about putting it on a timer, having the oven come on only long enough to keep the moisture out of the normally closed oven.
My current stock consists of 6010, 6011, 6013, 7018, 316/316L and about 4# of UTP65 believe it or not.
I was thinking that having the oven come on once or twice a week for 30 minutes to an hour at 120-150 degrees ought to keep the humidity in the oven to a minimum.
Any thoughts/suggestions?
as always
peace and love

Billyo, Go online and Google "storing welding electrodes" and you will find information provided by Lincoln, Hobart, and other electrode manufactures on the proper storage of electrodes. You will find on the wet side of the mountains in the PNW that intermittent operation of a rod oven is not recommended. Room temperature and dry, is acceptable storage for some electrodes but low-hy and others require special treatment for optimum performance. No disrespect to anyone but when "farmer welding" of mild steel you can violate a lot of rules and stick the job together but working with steels with a tensile strength of 50K and higher you should read the book and be familiar with the recommend procedures and you will maintain your reputation as fine welder.

7018 and other low hydrogen rods need to be kept dry as the flux is metallic base. If you do not get in and out of the oven repeatedly you can get away with a 25 watt light bulb set up that you would have to install. But for ordinary purposes, as log as the flux does not soak up moisture an oven is not necessary. Here in the PNW we often had to weld with 7018 in the rain. If your rod does get wet it should be heated up 400 degrees for an hour with the door cracked to allow the moisture to escape. I used an old RV refrigerator and light bulb for years. Of course, if you are doing coded welding, high pressure pipe, etc the rod needs to be protected.

Lyn - I visited my local welding supply store today and that's what they said too. They warned me against any welding that will be inspected with x-ray, but for my purposes, just use 'em and don't worry about it. As far as my reputation as a welder....we've never met, have we??? Not sure if "fine" is an appropriate adjective....actually, I'm pretty sure it's totally inappropriate.
Gene - Thanks for the reply and I didn't think of the light bulb, but that should do the trick...
