OTC History

OTC DAIHEN, initially known as OTC America (Osaka Transformer Company), set up its first office in Charlotte, NC in 1979. Originally a supplier of only welding equipment for other transplant companies, OTCA soon became a leader in the Japanese automotive market as a provider of gas metal arc welding supplies.

Dynamic Robotics Division

In the late 1970's, OTC Japan developed its first generation of dedicated arc welding robots. The first of these robots, THOR, launched in 1981. OTC America entered the robotic business in North America in 1983, and continued to refine automation welding with its ALMEGA line of robots. In 1985, OTC DAIHEN became the official OEM supplier of robots to Miller Electric Co.

In 1995, Miller announced its departure from the robotics business. In order to maintain the high volume of robots installed, as well as to continue selling to new users, OTC DAIHEN Inc. launched its Dynamic Robotic Division and moved the U.S. headquarters to Ohio.

The first series of robots sold in the United States with the OTC DAIHEN name utilized the Dynamic Robotics (DR) Controller. This was followed by release of the EX series in 2001, the AX series in 2003, the AII series in 2008 and the current model FD series in 2012.

OTC DAIHEN Continued Growth & Expansion

In an effort to unify the direction of the company and improve communication, the Welding Power Supplies Division and the Dynamic Robotic Division of OTC DAIHEN Inc. combined in 2001. The company established its headquarters in the Dayton, Ohio area.

OTC DAIHEN has expanded by adding branch offices in Charlotte, NC, Atlanta, GA, Novi, MI, and Monterrey, Mexico.

OTC DAIHEN continues to grow and live up to the company mission: Meeting the Challenge.
