Drain the oil out of the frame.
Good point. Will do!
Anyone else have suggestions?

No need for oil draining since there is no oil anywhere near that.
Are you responding to me or jess?

IMO...
I'd leave the oil in it to act as a heat sink. Also take some wet towels to wrap around the frame a little bit away from the tab to minimize the heat transfer through the frame. As most know, the frames are heat treated and welding will definitely diminish the treating. I'd say you should go ahead and cut out a piece of gusset from some 1/4" aluminum to weld on the tab and frame, too. I fixed one and did a fair amount of build up a few years ago. It eventually broke through again- I couldn't believe it. V groove the tab and frame so you're getting penetration all the way to the middle of the tab (a good welder would probably do that for you). Then, change the oil.
