In order to weld, put the machine without carriage onto the floor and align and fix it by the
leveling legs.
The plastic pipes are clamped in the clamping devices.
Afterwards, cut the pipe ends plane and parallel by means of the
cutter
and check the pipe
mismatch.
The cleaned and heated heating element is inserted and the pipes are pressed against the
heating element under defined adjusting pressure. This process is called
"adjusting"
.
After the prescribed bead height being reached, pressure is reduced, the
heating time
begins.
The function of this time is to heat up the pipe ends.
After expiration of the heating time, the slides are opened, the heating element is moved out of
machine in the basic position and the pipes are driven together again.
The time gap from moving out of the heating element until moving together the pipes is called
change over time
.
The pipes are joined under prescribed welding pressure and then cool down under pressure
(
cooling time
).
The welded joint can be unclamped, the welding process is finished.
Heating element heats
the pipes up to welding
temperature
Finished welding with
internal and external
bead
