THREE BUSINESS UNITS, ONE GOAL: TO SET THE STANDARD THROUGH TECHNOLOGICAL ADVANCEMENT.
What began in 1945 as a one-man operation now sets technological standards in the fields of welding technology, photovoltaics and battery charging. Today, the
company has around 5,660 employees worldwide and 1,321 patents for product development show the innovative spirit within the company. Sustainable
development means for us to implement environmentally relevant and social aspects equally with economic factors. Our goal has remained constant throughout:
to be the innovation leader.
