History of MWSCO

Dedicated to Customer Success Since 1939

Since 1939, a network of dedicated Driver-Salesmen served customers in the Minnesota, Wisconsin, and Iowa, under the company name AIRCO. When Don Peterson bought the company in the summer of 1973, the company name was changed to Mississippi Welders Supply Company, a name that defined our territory along the Mississippi River, which runs along the Tri-State region we serve.
