From your previous video your welder is up too high and possibly your wire feed is too slow. Also the sif should be spot or plug welded under the rubber seal. The repair will be really weak how it is.
Thanks mate - I have the welder on the lowest settings but will try a faster speed. I’m no professional and the car was going to be scraped, just seeing what I can learn and I do appreciate the advice.
@leoncosterbmx9101 no worries. I'm not a professional but do quite a bit of car related repairs. If you can get a gas MIG welder you will make you life a lot easier too. The flux core is of for heavy duty steel but thin body panels aren't ideal.
