Weld with 3 batteries for better results. I welded with just two and it didn't have much penetration at all. I had to weld a piece of metal the my broken axle that was stuck in the birfield. I had to pull on the piece of metal so i could get the broken axle out of the birf. I used 3 pares of sunglass's and it worked fine. I don't know what kind of rod i have in my glovebox but it worked for what i had to do.
