Chengdu bear Valley and electric appliance co., Ltd. was created by welding experts, by a group of graduate students specializing in IGBT inverter and engine-driven welding equipment research and development, production and sales of high-tech joint-stock enterprises.

to development needs, company in Chengdu high-tech zone (Sector West) new investment in the domestic first-class modern manufacturing base for arc-welding equipment, company headquarters officially moved to its new base in August 2010. the company covers an area of 24,000 square meters, owns 16,000 square meters of modern production testing workshop, a number of production lines and sophisticated testing equipment. the company's existing staff of the staff college education in 50%, has a master of science in engineering and MBA degrees in several technical and management personnel.

over the years, bear Valley companies adhere to the "market in depth, and be pioneers" technical innovation of philosophy and the "green energy saving, efficient and reliable" product design concept, forming a strong technology research and development team, every year there are more than one new product launches. in 2001 the company successfully developed the D7 series of multi-function IGBT inverter welding machine, has filled the domestic blank, replace the imported products, broke the welding machine market is dominated by foreign products, widely used in the construction of oil and gas pipelines. at the same time the product also received the national innovation fund project funding, China petroleum engineering construction system awarded recommended products.2004 year the company has introduced a D7 upgrading of welder MPS-500 welding machine, was welcomed by the oil and gas pipeline construction units, known as "China's long distance pipeline welding experts." in May 2008, the company received the national development and Reform Commission, Office of the file (the change-higher "2008" 1135th), I declare the MPS based on IGBT applications of semi-automatic welding of piping equipment industrialization project of project funding, is the national recognition of bear Valley company is committed to product innovation and encouraging.
