I understand your concern but isn't this getting carried away? I believe
the guy is welding ONE nut to ONE washer and doing it outside.
Even if he screws it up and has to weld TWO..I don't think he will get
enough zinc to matter.
Unless the nut is the prop nut for a tanker or battleship :-)

FWIW..Ive welded a few small galvanized objects with no ill effects noted.

If your welding on Zinc coating or Galvanizing coated and even in the
outdoor. Your going to pick up on the vapors and will give you Industrial
Neumona . The cure to prevent you from screwing up your lungs. Drink 2 to
4 oz. of milk before starting,. then every 1 to 2 hour of welding drink 2
to 4 oz. of milk to counter react the poisin effect of the fumes. This is
not a cure but will slow down any effects of the vapors on your body. The
milk has calcium which will attach it'self to the zinc or Galv. vapors
material while in your blood stream and it will be taken out by you
kindeys. You can use anyother stuff with calcium in it.
