What to disconnect when arc welding on the floorpan? 200 1992

Hello all. I have a 1992 240 with 3-4 small (2-3 sq. in.) rust holes in the floorpan. This weekend I plan to patch them using a wirefeed arc welder. I will be using shielded core wire. I will be able to ground the metal pretty close to the holes, but I still don't want stray current frying my electronics.

I now plan to disconnect the battery, the ECU, and the SRS control module. Are there any other items that need to be connected or removed? Any other things I need to consider or be aware of? The carpet and seats are out and my work areas are clear of any wires or cables.

Thanks, and wish me luck! This is my first big Volvo welding job.
