Contrary to popular belief you can weld galvanized safely. Do two things:
1. - If you are going to weld galvanized extensively - get an appropriate
respirator there are units made specifically for welding galvanized..
2. - Put a small fan behind you when you weld to push most of the fumes away
from you - not so strong that it blows away the sheilding gas, but strong
enough so you don't suck the fumes into your lungs.
P.S. - exhaust systems made from galvanized fence pipe last a very long time...
