No you absolutely can not seal it first.

You will seal it afterwards.

Cheers.

Ive never tried it with seam sealer,but I used to spotweld through silicon years ago manufacturing household skylights.

It used to burn a bit and stink a lot,and would blow holes if the silicon had started to go off.

Try it on some scrap steel and see what happens.

Just a tip when spot welding,make sure the surfaces are touching before you try to spotweld,or you will blow holes in the steel.

If you try to use the spotwelder as a clamp,you will blow holes.

Personally,I would seal it after welding.

Run a bead along the top, if you have access to the bottom run a bead along there to, or just fill it with tectyl.

Just make sure when you do weld you've got a air blower or water handy to put any fires out started from welding near the seam sealer that may still be between the panels. Cause that shit burns good!
