Rothenberger ROWELD P250B Premium CNC SA Bedienungsanleitung Seite 38

ROWELD P500-630B: consisting of six wide-surface shells and two small-surface shells (for di-
ameters 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 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.
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: For pipe-to-fitting connections, the spacers must be swivelled to the other side
and engaged in the middle clamping elements.
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.
 Start the welding process with GO.
In this final overview, the last changes can be made by clicking on the relevant subpoint and
confirming with GO.
In CNC mode, control is executed by the touch PC. All functions outside the touch PC, except
for the power key (6), are blocked.
The welding process can be cancelled by the power key. The key lock is then raised and the
relevant message appears in the display.
