EHD 7×7
Vertical reach 1 500–8 500 mm and boom reach 1 250–8 250 mm, with motorized column rotation.
PEMA EHD is an extra heavy-duty column and boom series for very demanding welding automation. Each unit is built to the customer's production requirements, for heavy SAW, multi wire SAW, strip cladding and narrow gap welding.

PEMA EHD is an extra heavy-duty column and boom series for very demanding welding automation purposes. The machines are always built to fulfil the customer's specific production requirements and are suited to heavy SAW welding in tailored automation cells.
The series is ideal for multi wire SAW processes and also covers strip cladding and narrow gap applications, on longitudinal and circumferential seams. It is easy to integrate with PEMA positioners and rollerbeds, and optional accessories include flux handling, a camera and control systems.
Six sizes are available, from EHD 5×5 to EHD 10×10. The EHD 5×5 offers a vertical reach of 1 500–6 500 mm and a boom reach of 1 250–6 250 mm, while the EHD 10×10 reaches 2 100–12 100 mm vertically and 2 000–12 000 mm with the boom. Column rotation is motorized.

Vertical reach 1 500–8 500 mm and boom reach 1 250–8 250 mm, with motorized column rotation.
The EHD series is used for heavy submerged arc welding and cladding in custom automation cells.
