HWH Welding Controllers

Harms & Wende stands for innovative welding technology for more than 70 years.

The Harms & Wende QST has assumed the regional representation of the Harms & Wende Group in East Germany, Czech Republic and Slovakia. The central location allows customers to be served, quickly and reliably. In our competence center, in addition to service tasks, we also undertake the development of new products or special adaptations to the tasks or environments of our customers. You can obtain additional information on the subject from the homepage of Harms & Wende.
