3.2.2. Welding preparations

 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 accessories kit.
P250 – P355 B PRO CNC: consisting of six wide-surface shells and two small-surface shells
P500 - P630 B PRO CNC: 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 sections) 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.
Pipe / fitting P250 – P355 B PRO CNC:
 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.
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 element. Thus, the
movable clamping element can be shifted on the rod as space requirements demand during clamping.
When some fittings are being processed in certain positions, such as horizontal bends or welding necks, it is
necessary to remove the heating element take-off device.
Pipe / fitting P500 - P630 B PRO CNC:
For pipe-to-fitting connections, the spacers must be swiveled 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 element. Thus, the
movable clamping element can be shifted on the rod as space requirements demand during clamping.
