The PRC welding head is a further development of our PRB The PRD 100 welding head is designed for precision, quality
welding head. The PRC features a zig-zag weaving movement and technology of the highest class. It is a TIG welding head for
and arc voltage control, which produces higher productivity and tubes with an outer diameter of 100 mm and upwards. The PRD
