Operating instructions ECOS 160/250/315
7 Fusion preparation
Clamp the components to be jointed in that way, that the pipe/fitting ends reach out at
least 30 mm from the clamps (ECOS 250 – 315) in order to perform a proper weld.
Make sure they are exactly aligned in the axial direction.
ECOS 160 is equipped with a stroke indicator. When pipes are
Attention
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!

If necessary, the components can be turned or the clamping force changed to achieve a
better clamping position.
