In order to weld pipes and/or fittings with an outer diameter smaller than
the clamp of the base machine, insert matching clamping half shells
and fasten them with the screws.

Clamp the components to be jointed in such a way that the
pipe/fitting ends reach out at least 30 mm from the clamps in
order to perform a proper weld. Make sure they are exactly
aligned in the axial direction.
If necessary, the components can be turned or the clamping force
changed to achieve a better clamping situation
Here below some recommendations in order to avoid damages to the
heating element when it is working in combination with the pulling off
mechanism:
Must be a gap here during the complete carriage stroke when moved pipe
is in contact with the heating plate.
Must be a gap here during the complete carriage stroke when the steady
pipe is in contact with the heating plate.
Gap must be 20 mm on both sides at final working position!
To get a correct alignment and to properly assists the
horizontal movement of the pipes, use roller supports!
