Another way when you have more access is to keep the arc on the plate and let the weld puddle kinda 'drip' down onto the sheet metal. gotta move quick enough that you don't blow through the sheet, but I had good luck with that welding the plates to the floor.
I have used the same method as above and it works but does take a bit of practice to get the right balance.
