We have engineered a hydraulic clamping device that ensures precise and secure
clamping of both the tube (cylinder) and the bottom. The clamping is done from the inside of
the tube which ensures that it is round and also includes protection gas flow. That allows for
automatic welding without the need for prior tack binding welds. The inner device is equipped
with a built-in argon underflow via a special backing bar to protect the root of the weld.

The machine can be opened at its end for the insertion of tubes. The tube is supported on
two sides. At the back there are bearing supports that can each be manually extended to fit
the required diameter. The bearings can also be moved longitudinally (motorized) depending
on the tube length. The front support is the aforementioned hydraulic clamping device with
copper rail, which can be replaced as needed based on the diameter of the tube.
