Fusion preparation
7.1
General information
The fusion process described in the following chapters is based on the
instruction sheets and guidelines issued by the DVS 2207.
The fusion area should be protected against the influences of weather
(humidity, ambient temperature <+ 5 °C, extreme direct exposure to
sun) with such measures as pre-warming the fusion materials, tents or
heating.
For optimal use of the CNC 4.0 400/500/630 the operating personnel
should be specially trained by Georg Fischer. In-depth knowledge of the
machine and it´s components and competence rule out handling errors
thereby also preventing faulty fusion joints.
7.2
Preparations
The standard configuration of the base machine is set to joint pipe to
pipe by using 2 clamps to fix each pipe in the base machine. The planer
and the heating element are inserted between the two central clamps.
In order to clamp particular constructions or T-pieces or to use a flange
adapter, shift the clamping unit B to the required position. To do this, the
two spacers C (upper and lower) from the original position, position the
clamping unit B and fix it with the two spacers C. The pipe preparation
and welding position is now changed, insert the heating element into
the pull-off mechanism between A and B.
Clean the couplings on the base machine and the hoses.
Connect the hydraulic hoses to the base machine and to the hydraulic
unit.
If the hydraulic hoses are not used, cover the couplings with the
protective caps. Clean the protective caps first.
Replace the heater if the PTFE -coating is damaged. Failure to comply
could impair the quality of the fusion weld.
