We’re proven problem solvers with decades of experience and innovation in the gas industry.


Our history of innovation has always been driven by the needs of our customers. We began our journey by serving gas distributors over 50 years ago, with the development of our patented palletization system, including filling, storage and transportation. Today it is the most widely used system in North America.

When there was a demand for better gas filling consistency and quality we developed automation solutions. Our patented automation brought additional benefits in the form of greater productivity, reporting and remote monitoring. We are proud to be considered the global leader in gas filling automation.

As new applications for gases in manufacturing began to emerge we met the challenge with specialty gas solutions to deliver on the growing demand in emerging markets. Constant innovation has become our hallmark, one which our customers have grown to depend upon, and so can you.


We are a US manufacturer that designs, engineers, manufactures, assembles and installs our equipment.

The equipment we built decades ago is still operating today, doing what it was intended to do and more. Clients that made initial investments have continued to engage us in the development of additional solutions to grow their businesses.

Regardless of the scale of the solution we provide, you can expect:

  • Quality manufacturing
  • Performance testing
  • The use of advanced technologies
  • Training and Support
Reinvestment in our own equipment and systems ensures the best for you.

We wouldn’t expect you to invest in us if we weren’t reinvesting in ourselves.  Whether it’s training our people, adding new equipment or upgrading our ERP system, we are constantly improving ourselves in order to provide the best for you.

Over fifty years ago, Founder Richard Bennett created Weldcoa to support his Gas & Welding Distributorship, Benster Welding. We have been supporting the Cylinder Gas Industry ever since.


Weldcoa creates first American Palletized System in response to overseas distributors entering the US market.


Weldcoa introduces the LowPro Gas Pack. The LowPro was so named due to its noticeably lower center of gravity than competitor products. In time, it becomes the most used gas pack in North America.


Weldcoa designs and manufactures the first Inverted Medical Cylinder Fill Rack in response to their client’s complaints on moisture/ corrosion of the medical cylinders internal walls. Prior to this innovation, all medical cylinders were filled vertically.


Weldcoa begins to manufacture linear and palletized cylinder plants for clients.

Hector Villarreal, Weldcoa’s current President and Co-Owner, joins the Weldcoa Team. Maynard “Bud” Klotz, Weldcoa’s current Vice President and Co-Owner, joins the Weldcoa Team in 1996.


Weldcoa develops and introduces first ever Modular Palletized Fill Facility. Prior to this innovation, all fill plants were built on site. Modular design lowered the cost of the build and the install. It also increased the speed in which a plant could be installed and go-live.


Weldcoa develops, designs, builds and installs its first Automated Filling System for the filling of straight gases. The client, Interstate Welding, likes the system so much that they immediately ask Weldcoa to develop an Automated Mix Gas System. The Mix Gas System is installed several months later at Interstate in Marinette, WI. That system is still fully operational and filling cylinders today.

And that is just the first 30 years!

Our timeline is being updated and more will be posted shortly.
