Orbital welding head
0.05 - 6.15 rpm, ø 1 - 2.4 mm | A21 series
ESAB
The PRB welding head is compact and easy to use as a result of its unique pincer action which reduces setting-up times to a minimum. The welding head is positioned and secured around the tube with great accuracy in seconds. The PRB welding heads are available in three sizes for tubes with outer diameters of 17 to 170 mm.
A21 PRC
The PRC welding head is a further development of our PRB welding head. The PRC features a zig-zag weaving movement and arc voltage control, which produces higher productivity and better welding quality, particularly when welding thick-walled tubes.
A21 PRD 100
The PRD 100 welding head is designed for precision, quality and technology of the highest class. It is a TIG welding head for tubes with an outer diameter of 100 mm and upwards. The PRD 100 is very compact in design and, as a result of its low profile, requires only 73 mm of clearance around the tube.
A21 PRH
ESAB’s 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.
