Allied Gases & Welding Supplies, Inc was founded in Phoenix, Arizona in 1995 by Mark and Anthony Boccaccio, along with C. Thomas Shaw. From our modest beginnings in Phoenix, we have expanded to multiple locations in Arizona. In 2008 we relocated our production facility and headquarters to Tempe, Arizona.

We at Allied Gases are continually focused on expanding our technical knowledge and product base to better meet our costumer's needs.

In 2003, Allied Gases joined the elite group of Independent Welding Supply Distributors Cooperative, The IWDC. This membership has allowed us to expand our welding supply and industrial gas lines while offering the most competitive prices available.

In 2007, Allied Gases was proud to offer our customers Micro-Bulk, a new and improved gas delivery system and in 2009, we introduced our Medical Gas services. We continued to expand our gas product offering in 2011 by committing additional energy and resources into our Specialty Gas production lab.

Throughout our history, Allied Gases has always had a reputation as a market leader by offering the most current technology and continually exceeding our customer expectations.
