The wind tower, measuring 443 feet tall, was constructed in June 2011 at the Lincoln Electric world headquarters and manufacturing campus in Cleveland, Ohio. This installation is the largest known urban wind tower in North America, and is capable of producing 2.5-megawatts of electrical energy, or approximately 10 percent of the requirements for Lincoln Electric’s main Cleveland manufacturing facility.

The tower project is truly a global endeavor:

    • The 'can' sections were fabricated by Katana Summit, LLC in Columbus, Nebraska using Lincoln Electric Power Wave® AC/DC 1000® SD unitsPower Feed® wire feedersLincolnweld® flux and wire

    • The blades, formed from glass fiber reinforced polymer (GFRP), were produced in Poland by the world’s leading supplier of wind tower blades, LM Wind Power.

    • The turbine was designed and manufactured by KENERSYS of Germany. It features KENERSYS' innovative SYNDERDRIVE TECHNOLOGY – a proven, load-optimized mechanical drive train system.

The project represents important cost savings, as well as the Company’s commitment to integrating renewable energy sources into its manufacturing processes.

Even more importantly, it stands as a symbol of Lincoln Electric’s commitment to the wind tower fabrication industry – showcasing the unique benefits that Lincoln Electric products and welding solutions offer to a prominent, fast-growing business segment.
