DALEX Welding Technology's company history

In 1911, the founder Carl Niepenberg, was a handwork master in metalworking industry around Solingen. The “Niepenberg & Co. GmbH” became part of the commercial register in 1922, as a steel goods factory that produced roll and razor blades. In 1936, the first welding transformers were produced in small pieces, and up until the 1950s their focus lay in international renowned razors. A new mile stone was reached in 1945, with the production of the first spot welding machine. At the beginning of the 1950s, DALEX entire production was transformed towards compact welding transformers. In 1952, the company was renamed and the brand DALEX was introduced. Strategic investments and acquisitions meant that DALEX lay the foundation for an extensive distribution network in the 1960s, and it advanced to become a market leader of standard welding machines. Innovative special welding machines strengthened their market position continuously in the following years, which meant that they were able to overcome the crisis between 2008 and 2010. Research and development are also of great importance, which meant that modern and high tech machines were produced and serviced.
