Group,


Calcium carbide is the substance for making acetylene.  Water plus calcium carbide yields acetylene.  Acetylene is unstable in high pressure oxygen and, therefore, containers of calcium carbide may be transported without fear of explosion.

 I very much doubt that calcium carbide output would be used for welding: just too slow, difficult to regulate

    When I was in Korea around 69/70 they had small containers? that used it for just that, welding.  Saw lots of them.
