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 that 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 position.
Adjustable roller supports or a floating suspension assist horizontal
movement of the pipes fixed in the carriage.
Attention When pipes are positioned into the base machine, close the carriages till
the pipes are in contact with themselves. Control the position of the
stroke indicator in relation to the red mark (cylinder stroke end). If the
indicator is close to the red mark, during the welding procedure no
pressure could be transferred into the welding zone! The weld will not
perform !! Change the clamping position of the pipes! After planning the
pipe ends, the distance between the indicator and the mark has to grant
the movement during bead build up, heat soak phase and bead roll over!
