A-OX Welding Supply: 73 Years of Innovation and Growth

Follow the timeline of A-OX Welding Supply, from its founding in 1944 to its current status as a leader in the industrial gas and welding supply industry, marked by innovation, growth, and family ownership.

Dakota Welding Supply Company was founded in Watertown, SD

A year later, Sioux Welding Supply Company was founded in Sioux Falls, SD as an associated business handling the same lines of product as Dakota Welding Supply.

Dakota Welding Supply Company and Sioux Welding Supply Company are merged under the Dakota Welding Supply Company name

Dakota Welding Supply Company continued to serve eastern South Dakota and western Minnesota. By 1956, Dakota Welding Supply had three warehouses in Sioux Falls, Watertown, and Huron, SD, as well as a fleet of 11 trucks and numerous dealers throughout the region.

Harold Elliott founded A & B Welding Supply in Rapid City, SD

Harold decided to leverage his experience working in a welding garage to begin selling welding supplies and gases from his truck. His two oldest sons, Donald and Robert, joined him in the business, and it grew rapidly.

When Harold and his sons had the opportunity to purchase Dakota Welding Supply–then based in Sioux Falls–they took it.

Harold passed away in the Black Hills Flood trying to save his business

After his passing, Harold’s sons Donald and Robert owned and operated the businesses; Robert at Dakota Welding Supply in Sioux Falls, and Donald at A & B Welding Supply in Rapid City.

Eastern business changed from Dakota Welding Supply Company to A-OX Welding Supply Company

The business of Dakota Welding Supply had grown greatly and expanded far beyond South Dakota’s borders.

Donald’s sons, Thomas and Michael, purchased both businesses from Donald and Robert.

Today, Michael runs A & B Welding Supply in Rapid City, and Thomas runs A-OX Welding Supply in Sioux Falls. They are proud to be the third generation to continue the family business.

Since Thomas took the reins of A-OX Welding Supply, he has continued the vision of innovation, fully embracing state of the art technology to assure A-OX Welding Supply’s future in the 21st Century. Thomas’ wife, Linda, has worked hard by his side for the last 35 years and also works at A-OX.

A-OX Welding Supply moved to its current location on Harlem Avenue in Sioux Falls.

We now occupy a beautiful 46,000 square foot facility. The new location features a state of the art ISO/IEC 17025:2017accredited specialty gas laboratory, an automated fill plant, and facilities for advanced gas cylinder testing and reconditioning.
