3. Functional description
All international and national process guidelines are to be basically
followed!
The plastic pipes are clamped by means of corresponding clamping tools.
Afterwards, the front sides of the pipes are equally planed by means of the planer and the pipe
mismatch is checked.
In case of contact welding, with mounted attachment plates, the heating
element is driven in and the pipes are shifted to the heating element on aligning
force.
After expiration of the aligning time, the force is reduced (heating force = 10%
of the aligning force), the heating begins.
The infrared welding is effected without the aligning since it is a touchless
welding process!
The attachment plates must not be mounted!
The heating element is driven in and the pipes are shifted in front of the heating
element on defined distance (limit stop), the heating begins.
The heating time is necessary to bring the pipe ends up to the welding temperature.
After the heating time has elapsed, the slide is opened, the heating element is moved back
and the pipes are joined again. (change-over time)
The pipes are joined by the required welding pressure and cool down under pressure as well
(cooling time).
After the cooling time, the welded pipe can be unclamped.
The welding processes are logged and can be printed via the parallel interface of the SPA in a
long or short version, or stored to a SD card.
Infrared welding (option): Contact welding:
Heating element heats
the pipes up to the
welding temperature
Completed welding
connection with internal and
external bead
Infrared heating element
touchlessly heats the pipes
to the welding temperature

4.2. Planer
In order to carry out planing put the planer between both workpieces and lock it by turning
the locking tin disc and star grip screw.
Press button to “ON”, the planer discs start turning. Now you may additionally press the
locking button, the planer is running permanently until you deactivate the locking button
again.
In order to carry out infrared welding you must plane the pipes as long as the planer rests
against the limit stop screws on both sides. Thus, the pipes have the prescribed distance to
the heating element during welding.
Especially beware of cutting injuries!
Only activate the planer if it has been put into the machine and secured by
locking tin disc and star grip screw.
The limit stop screws are factory-set. As soon as the limit stop screws are
altered, the radiation distance changes.
Always coordinate the limit stop screws of planer and heating element.

4.3. Heating element
The heating element is guided on a linear guide rail and is
manually shifted in and out of the welding area by the grip.
The infrared heating element is coated by ceramic and
should not be touched by the welding pieces.
The distance (pipe to heating element) is prescribed by the
limit stop screws of the heating element, 3 screws on both
sides (chapter: 4.3.1).
4.3.1. How to adjust the limit stop screws
The limit stop screws are factory-set. The pan-head screws are shimmed by a washer and
entirely screwed in.
If you wish another radiation gap you must:
Slightly detach the screws,
or replace the pan-head screws by screws with changed head height.
We recommend the adjustment of the gap only with cooled down heating element.
Especially beware of the heated heating element!
Drive the planer into the machine, put the tables together and lock them.
Measure the dimension „X1“ between the clamping tools.
Repeat this afterwards with driven-in heating element, record the dimension „X2“ between the
clamping tools.
The dimension „X1“ with planer must be 2 mm larger than dimension „X2“ with heating
element.

4.3.2. Heating element with attachment plates
We recommend the replacement of the attachment plates only with cooled-down
heating element.
Be especially cautious during the replacement, if the heating element is heated
necessarily wear safety gloves!
Always brush the fixing screws prior to the assembly with high temperature paste!
In case of infrared welding you must necessarily remove the attachment
plates prior to heating since the plates are destroyed by the high
temperature.
4.4. Heating element control
Put the heating element plug into the 10-pole-power socket and secure the plug connection
by the safety bracket.
As soon as the heating element has been plugged and the control unit activated, the heating
element is heating up to the adjusted temperature.

4.5.1. Height adjustment
The right clamping tool may be adjusted in order to compensate
the height.
For this purpose detach the pan-head screws and shift the
clamping tool on the sloping platform (arrow) until the height is
balanced.
Afterwards necessarily tighten the pan-head screws again.
4.5.2. Cross adjustment
The left clamping tool may be adjusted in transverse manner to
the axis in order to compensate differences.
Detach the two pan-head screws on the left side and shift the
clamping tool (arrow) until the difference is balanced.
Afterwards tighten the 2 pan-head screws again.

Keep the machine dry!
The use on buildings sites is only allowed via current distributor with FI safety
switch according to VDE 0100.
The machine must not be stored close to inflammable material.
There is the danger of ignition since the heating element is heated above 500°C
with infrared welding (option) and above 220°C with butt welding on contact.
No toxic vapors result from welding temperatures up to 260°C.
Higher temperatures may cause toxic vapors, therefore absolutely care for good
ventilation and exhaust.
Only instructed and authorized personnel is allowed to use the machine. An exam
for plastic welding to get qualified can be passed according to DVS and DVGW.
Switch off the machine after the completion of welding works and in long non-
operative times. Furthermore, make sure that no unauthorized person may have
access to the unattended machine.
