| 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 five sizes for tubes
with outer diameters of 17 to 170 mm.
Use these welding heads together with the Mechtig, Prowelder
and Protig power sources.
Delivery includes
The PRB comes with 7 m of connection cable (current, gas,
water).
