TIG control


The proven VIETZ units of the GDV generation – that are 100% secure for vertical-down welding – have become indispensable around the world.

These units have been delivering reliable welding performance for many years, especially for use on pipeline construction sites. In addition to the electrode hand welding process, other welding processes have become more and more prevalent.

Professional TIG welding in pipeline and plant construction applications is becoming more and more popular. This has led us to further develop the existing TIG control system from Vietz. The result is a fully-fledged, high-performance 300A TIG system, which gives you the opportunity to easily weld using the TIG or electrode hand welding methods.

Due to the compatibility of all components, we can easily retrofit the TIG control module to almost all units of the GDV product line.
