Never heard of any warnings against welding zinc passivated steel -
only
know of cadmium plating being very dangerous.

You will only weld or braze galvanized steel in a poorly ventilated
space ONCE unless you are REALLY stupid.

I have never become aware of the dire consequences of welding zinc
plated that are being spouted here.

"galvanised" can be plated with *ANY* metal that has a higher galvanic
affinity than the host metal. Including cadmium and various other toxic
heavy metals.

Cadmium poisoning is cumulative and has various routes into the body -
its a long slow painful journey to a Darwin award.

For a few years I worked assembling electronic equipment on cadmium
plated chassis - I've seen with my own eyes the extent to which the
plating rubs off on your hands.

But if you're too stupid to take it from someone who's been there -
Darwin awaits you with outstretched arms.

Can you not see your post's internal inconsistency?

You have multiple people who have given citations as well as related
experiences about welding zinc galvanized steel, but you discount them
saying "I have never become aware [of that problem]."

Yet you insult those who YOU think are "too stupid to take it from
someone who's been there..."

Sheesh.
Must be the painted cow's twin brother - - -

Nah, just another old guy with 20 or 30 years in the trade telling you
that you are full of it.

A bit more than that, and more than one trade - one thing you're not full of
is practical experience.
Well, I've had LOTS of practical experience and more than one trade.
I won't go through it again for your benefit, because it won't change
your mind anyway. A lot of the guys on the list know my history and
experience.
