DeLille Oxygen Company was originally founded in 1924 by W.C. DeLille to supply ice and coal to the surrounding areas within Ohio. Soon after being founded DeLille moved into the welding supply industry and was a supplier of gases and hardgoods for that particular industry. 

DeLille continued on the path of welding supplies and added multiple locations throughout Ohio. DeLille has continued to expand to serve different industries throughout different areas with welding supplies and gases. DeLille has Ohio locations currently in Columbus, Marion, Springfield, Lima, Wilmington, Lancaster, New Boston and Zanesville. Although the Columbus location is the main manufacturing facility and headquarters, each branch of DeLille has their own gas manufacturing to some extent in order to fulfill their customer’s needs as well as to build a reliable network of back-up for each other.
