Awhile ago Ernie's school was surplusing some welding rod so I picked up a few fifty-pound cans of 8018. Today I finished up my last 7018 so I opened my first can of 8018. Burns real sweet!
I know in the shipyards when they opened 50# cans the rod went straight into the huge welding rod ovens where they were kept at something like 250°. I don't own a welding rod oven nor would I want to keep this much rod hot for as long as it will take for me to use it up (a long time). Should I attempt to put a semi-airtight top on the open can? Should I put desiccant in the can before I seal it? Should this (low hydrogen) rod really be heated before use?
