I used to work for a company called Union Carbide. They used to sell O2/N2 plants to companies like Praxair.

I believe Praxair used to be Union Carbide's air products division. I think it was called Linde.

I think it was called Linde.

I think you are correct. I believe the gas side of Linde became Praxair. The welding, cutting & automation portions of Linde was spun-off as L-Tec. I worked in automated cutting.
