The Airco Welding Supply Company no longer exists and there has never been an Airco website. Airco Welding Supply divided its product lines among other manufacturers, and the Controls Corporation of America (Concoa) now holds the bulk of the welding equipment business, as of August 2015.
Concoa.com features many Airco-branded products and replacement parts. Airco Welding Supply began operations in 1916 as the Air Reduction Company, a supplier of industrial gases. The company developed the first MIG welding system and produced welding equipment into the 1970s. Airco Welding Supply (not to be confused with Airco Welding Services, an unrelated firm) sold its welding equipment operations to ESAB in 1983 and retained its profitable industrial gas business. The British Oxygen Company eventually purchased the industrial gas business and was acquired by Linde AG in 2006.
