Putting Out Of Operation - Rothenberger ROWELD P 800 B Bedienungsanleitung

3.2.3
 While moving workpiece ends to welding position, read the workpiece drag pressure from
 Insert the heating plate into the basic unit between the two workpiece ends and make sure
 Engage the machine, set and maintain the required conformation pressure plus drag
 As soon as sufficient bead has formed around the entire circumference of the workpiece
 Now close the relief valve. Ensure that the workpiece ends still have contact with the heating
 After the warm-up phase, disengage workpieces, remove the heating plate and re-engage
 Regularly check the pressure and pump it back up when necessary. If the pressure loss is
 Put the heating element back into the storage case.
 After the joint has fully cooled, slowly release the pressure by pulling the relief valve, unclamp
 Disengage the basic unit, write protocol. The machine is now ready for the next welding
All welding parameters can be found in the enclosed welding tables.
3.2.4
 Switch off heating plate.

The workpiece drag pressure is the minimum amount of pressure required to set the
workpiece – depending on weight and length – in axial motion. This value must be precisely
determined; it will be necessary to engage and disengage the machine and workpieces
several times and to set the pressure adjustment valve until the machine almost comes to a
standstill. Add the drag pressure to the conformation, heat-penetration and joint pressure.
