Measures For Preparing Welding - Rothenberger ROWELD P160-630B Plus Professional Instrucciones De Uso

For lifting the milling equipment and the heating element, use lifting device 53410 or 53323, or a
suitable tool.

Measures for preparing welding

 Pipes smaller than the maximum welding range (diameter) of the machine, mount the
adapter clamping inserts suited for the pipe diameter with the Allen screws found in the ac-
cessories kit.
ROWELD P200B: Ø63-140mm: consisting of six wide-surface shells and two small-surface
shells. Ø160-180mm: consisting of 8 wide-surface shells.
ROWELD P160-355B: consisting of six wide-surface shells and two small-surface shells.
ROWELD P500-630B Plus: consisting of six wide-surface shells and two small-surface shells
(for diameters up to 450 mm) or 8 wide-surface shells (for diameters >500 mm).
In so doing, please observe that the small-surface shells are mounted to the two lower external
main clamps. These are used in the left basic clamping element below and above only for pipe
to pipe bend connections.
 Insert the plastic pipe or fitting in the clamping device (use dolly with longer pipe < 2,5m sec-
tions) and tighten brass nut on the upper clamps. Adjust brass nuts (tighten or loosen) to
compensate for any ovalness.
For P200B:
The machine is operated with 4 basic clamping jaws in the case

of pipes/ pipe connections (welding position A).
The 4th basic clamping jaw can be removed in the case of

narrow pipes/ fitting connections (welding position B). To do
this, initially remove the screws (3) and then slightly loosen the
screws (5). The 4th jaw can now be pulled out together with the
sub-construction. Finally, unscrew the spacers (4) and replace
them by the screws (3).
For pipe-to-pipe connections, the two spacers must be engaged in

both left clamping elements (standard configuration at delivery).
Attention: Under no circumstances should the spacers be installed diagonally offset!
The pipes are each held by two clamping elements.
P160B: For pipe-to-fitting connections, the two spacers must be en-

gaged in both middle clamping elements.
P250-355B: For pipe-to-fitting connections, the two spacers must be

engaged in both middle clamping elements, and the heating element
take-off device is suspended into the left clamping elements. When
some fittings are being processed in certain positions, such as horizon-
tal bends or welding necks, it is necessary to remove the heating ele-
ment take-off device.
P500-630B Plus: For pipe-to-fitting connections, the spacers must be

swivelled to the other side and engaged in the middle clamping ele-
ments.
Attention: Under no circumstances should the spacers be installed diagonally offset!
 The pipe is inserted into three clamping elements, and the fitting is held by one clamping el-
ement. Thus, the movable clamping element can be shifted on the rod as space require-
ments demand during clamping.
 Verify secure fit by moving the workpieces together.
