Re: Un-Galvinizing Sheet metal

Jim:
A welding prof. here at the college tells me that you were suffering from
"Metal Fume Fever" when you welded the Galvanized metal. It is caused by
Zinc Oxide fumes which are poisonous and are dangerous to your respiratory
system. He says grind galvinizing off and weld in very well ventilated
conditions. He says use caution when you weld the acid treated metal
because the heat and acid residue can be equally if not more dangerous.
Godspeed
