Change-over and Jointing

When the heating stage is completed, turn the hand wheel back to
remove the components to be joined from the heating element, remove
the heating element from in-between them and bring the components
in contact with each other using the hand wheel.
The longest acceptable duration for this stage of the welding process
is the one indicated for t
Immediately after contact is established between the component butts,
the jointing force has to be reached. Building this force, by continuing
to turn the hand wheel until the force indicator shows the value for
F , has to be done as a consistent and linear increase. F

F . In case of joints at an angle, instead of F use the computed

force F (see "Important" paragraph at the end of Sect. 5.1).
α
The force increase, to reach the jointing force, must not take longer
than indicated in the appendix.
5.7

Cooling Stage

When the jointing force is reached, keep the movable carriage of the
machine at this position, in order for this force to be kept. It must con-
tinue to be applied, while the joint cools down, for as many minutes
as indicated in the tables in the appendix. Like all other durations, it
depends on the wall thickness.
During this stage, no external forces must affect the new joint.

End of Welding

After the full duration for the cooling stage, before opening the clamps
and taking the new joint out of them, reduce the applied force to 0..

Troubleshooting

Issue
The electrical facing tool
does not operate.
or
The heating element does
not operate
The facing process does not
yield an outcome of the de-
sired/required quality.

Service and Maintenance

• Clean the machine completely at the end of every job, especially
if it is going to be stored for a prolonged period of time.
• Check that the shaft along which the movable parts move is always
clean.
• Check the clamps and their tightening mechanism for proper
operation.
• Check the PTFE coating of the heating element. Its surfaces
should be homogeneous and without scratches. If the material
homogeneity is compromised or the part is damaged, it should
be replaced.

Correction
1. The facing tool/heating ele-
ment must be connected to a
power supply, and the supply
must meet the requirements
posed by it.
The facing blades must be
sharp and the rotating blade
supports, in a good condition.
