Overview: The United States Welding Works Company began as a partnership in 1924 by Charles Lofgren and Adam Schmick. The original, small store was located in downtown Denver. The two men specialized in welding, which at that time included anything from difficult welding jobs to receiving parts and machinery in need of repair from all over the Rocky Mountain Region. From time to time customers asked if they would stock oxygen and acetylene to aid them in their welding jobs. Recognizing this opportunity, United States Welding Works Company was formed in 1928 as a supply house for atmospheric gases and welding supplies.The company continued to grow prior to and during World War II. In 1947, the founders decided to retire and sold the company to the sons of Charles Lofgren - Robert Lofgren Sr. and Walter Lofgren.

Carbon Dioxide
Carbon Dioxide, CO2, is a tasteless, colorless, odorless, nonflammable, liquefied gas. Carbon dioxide is an integral part of the basic life cycle in nature. It is exhaled by humans and animals, then used by plants to help them grow. Plants, in turn, release oxygen, which people depend on for survival

Gases for Gas Plasma Arc Welding (FCAW)
The physical configuration of PAW requires the use of two gases, a "plasma" or orifice gas and a shielding gas. The primary role of the plasma gas, which exits the torch through the center orifice, is to control arc characteristics and shield the electrode. The shielding gas, introduced around the periphery of the arc, shields or protects the weld. In many applications, the shielding gas is also partially ionized to enhance the plasma gas performance.

Hydrogen, or H2, is the lightest of all gases. Commonly found in nature in compounds with other elements, it is the most abundant element in the universe. Hydrogen is a component of water, minerals and acids, as well as an essential part of all hydrocarbons and essentially all other organic substances. In fact, 98 percent of the known universe - most notably the sun and stars - consists of hydrogen.

Oxygen, or O2, which comprises 21 percent of the earths atmosphere, supports life and makes combustion possible. The most abundant of all elements on earth, oxygen comprises 85 percent of its oceans and, as a component of most rocks and minerals, 46 percent of its solid crust. In addition, it constitutes 60 percent of the human body.
