The best thing to do is use a good stiff wire brush or sanding disk to
remove the galvanized coating from the areas to be welded. This reduces the
fumes and improves the look of the weld.
By the way, I've never felt ill after welding galvanized, but I usually weld
in a well ventilated area (open garage).
