Welding; Welding Of Segmended Bends; Putting Out Of Operation - Rothenberger ROWELD P 110 Instrucciones De Uso

Risk of injury! Do not grasp into the running knife while the trimmer is put into
operation.
 After the front sides are trimmed flat, which can be recognized by an uniform and unbroken
chip, slowly move the pipe ends apart. Unlock the trimmer by the swivel and remove it.
 Move workpieces together and check whether the welded surfaces are flat. If this is not the
case, trimming must be repeated.
The axial offset between the workpieces must not be more than 10% of the wall thicknes
and the gap between the flat pipe surfaces must be more than 0,5 mm (according DVS).
Otherwise adjust with help of the clamping screws and repeat trimming.
The trimmed surfaces prepared for welding must not be touched with the hands and
must be kept free of dirt.
3.2.3

Welding

Risk of crushing! Always maintain a safe distance from the machine when moving
clamping tools and pipes together! Never reach into the working area!
 Put heating element between the workpieces.
 Move pipe ends together and apply required adjusting force.
As soon as the required bead height is reached evenly over the entire circumference at the
pipe ends, reduce the force to the corresponding preheating force (near 0). It must be
ensured that the workpiece ends abut evenly to the heating plate.
 After finishing the preheating time, move pipe ends apart, remove heating plate and move
pipe ends together again within the max. change over time. Increase force as lineary as
possible to the corresponding joining force within the build up pressure time. The joining
force must be maintained with a tolerance of  6,66% during the entire cooling period
 At the end of the cooling period release the spring via handwheel. Unclamp and take out the
welded tube sections. The entire parameters can be found in the welding tables.
A complete list of welding parameters for various materials is provided in the
"Welding Parameter Handbook".
3.2.4

Welding of Segmended Bends

 Loose the screws in the base of the main clamps. Turn main clamps until the wished angel on
the scale is shown. Tighten screws again.
 Cut pipe ends in the required angel and clamp them in the main clamps.
 During trimming take care that the pipe ends are in the center of the trimmer disc.
This can be adjusted by loosen the screws at the bottom of the trimmer support pushing or
pulling the trimmer in the center of the pipe ends and tighten the screws again.
 Use the depending Welding table!
The angel shown on the welding table means the total angel of the welding.
Example: 30° = 2 x pipe end with 15° each.
Follow the instruction of „3.2.3 Welding".
3.2.5

Putting out of operation

 Switch off the heating element.
 Unplug the heating element.
 Store basic machine and tools into transport case.
Let the heating element cool and stow it in such a way that no adjacent
materials can be ignited!!
