End of Welding

When the duration for the cooling stage is completed, loosen the
locking bar, open the pipe clamps, and take the newly assembled
joint out of them.
If any problem was apparent in the course of the welding
process, any of the maximum durations was exceeded or any
of the previously computed force levels was not consistently
Important
maintained, the required quality of the weld is uncertain and
the welding process has to be repeated.

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 shafts along which the movable parts move are
always clean and lubricated.
• Check the clamps and their locking/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 piece is damaged, it should
be replaced.
• Check the facing tool for proper condition, in particular the blades
must be sharp. The blades can be turned once and work can go
on with their second sharp edge. When both edges are worn, the
blades must be replaced. Do not attempt to sharpen the blades
on your own, as such sharpened blades tend to be a hazard for
the workers and cannot ensure a proper facing outcome.

Correction
1. The tool must be connected to
a power supply, and the supply
must meet the requirements
posed by the facing tool.
2. The facing tool must fully rest
on the movement shafts (thus
actuating the micro-switch).
The facing blades must be
sharp and the rotating blade
supports, in a good condition.
