A21 PRH


ESABs PRH tube-welding tool is designed for welding thin-walled, stainless steel tubes in order to provide maximum gas shielding around the tube. The tool has been designed according to the chamber principle to produce this shield. This means that the rotating part and the Tungsten electrodes are enclosed in a gas chamber formed by the outer casing, which also constitutes the clamping arrangement for the tube to be welded.
The tube-welding tool is water-cooled and forms a complete unit which also incorporates the return conductor. It is available in three sizes, PRH 3-12, PRH 3-38 and PRH 6-76, making it possible to weld tubes of between 3 mm and 76.2 mm.
All three heads are equipped with encoder motors for precise positioning of each sector when welding with different sets of parameters.
Contenu de la livraison
8 m of connection cable (current, gas, water and return).
