As you near the end of your pass you have more heat in the metal that you are welding compared to the start. So at the end of the weld to properly fill the crater we need to reduce heat. That is most easily accomplished by increasing the arc length. So what I usually do is: Longer arc, small circle or weave at the end of the bead to fill the crater and then rapid break.

Most of do not weld every day, so there is nothing wrong with some warm-up practice on scrap metal.
