your in the .030 wire range, and maybe 75-80 amps on that oil pan
 
I agree with Grumpy! Are you going to weld it to the pan or are you going to set it through, which might seal better if is welded on both sides?

I'm planning to cut the hole, such that the hole perimeter meets the jam nut face about the outer
edge. That way I weld both sides giving me a better chance of sealing it without any leaks.

The bung for the temperature sensor is already designed to weld both sides.

Weld the inside first, take a dremel with a sharp tip and create a little groove between the bung and oil pan metal. Try to weld it as warm a setting as possible to get good penetration. If you get a good weld inside the outside won’t be as critical!

I tig welded my bung in the pan..But.. I would not be afraid to mig it. Make sure to start and direct most of the heat into the bung and dift onto the pan quickly then back to the bung. I would stitch as to keep the pan cooler.

Try to practice with a piece of metal sized to the bung and a piece of thin metal first.

Exactly what he said.
For bungs, I buy stainless steel flange nuts and drill & pipe tap them to the size I need.

Exactly. Plus if the plug was really tight, you have the hex to put a wrench on to pull against.
