We're in Everything You Do.
Born from the 2025 merger of Central McGowan and Minneapolis Oxygen — two family-owned Midwest businesses with nearly 80 combined years of expertise in industrial gas, welding supply, automation, and CO₂ solutions.
Two Legacies. One Mission.
CM2 Supply was formed in 2025 through the merger of Central McGowan and Minneapolis Oxygen, two family-owned businesses with deep roots in the industrial gas and welding supply industry. Together, these legacy companies bring decades of technical experience and a shared commitment to safety, service, and teamwork.
Our history traces back to 1946 with Minneapolis Oxygen and to 1947 with Central Welding. In 1965, Central Welding merged with McGowan Welding to form Central McGowan, setting the foundation for long-term growth built on customer relationships and investment in people.
Today, CM2 Supply serves many industries across the Midwest, including manufacturing, construction, energy, healthcare, universities, government, food and beverage, and more. We provide industrial, specialty, and medical gases, bulk tank solutions, welding and automation systems, PPE, consumables, dry ice, and specialty services including CM2 BevCarb and CM2 Automation.
Two Companies. One Shared Path.
