Can't help with the MSDS but start at google with a search on
manganese madness.

I am seeking to obtain copies of MSDS sheets for welding rods and
welding wire, used in manufacturing. In particular, I am looking for
older warnings given on the welding rods and wires. Anyone having
older MSDS sheets, please contact me.

This is very important, as it relates to wedlers who have contracted a
Parkinson-like disease from the use of these welding rods and wires,
and who we believe were given inadequate warnings given on the MSDS
sheets. We need to obtain these sheets in order to help these welders
in their claims against the manufacturers of these rods and wires.
