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 P250-355/8-12B:
 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 P500-630/18-24B Plus:
 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
element. Thus, the movable clamping element can be shifted on the rod as space
requirements 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.
