3 Product Description and Principles of Operation
3.1 Intended Use
The agru SP-110S Welding Machine is designed exclusively for welding
plastic pipes and fittings using the infrared welding technique (butt welding
without contact).
Only the welding parameters shown on the touchscreen display (prepro-
grammed by the manufacturer or defined by the user) can be selected for a
welding operation. Any modification of the welding parameters contained in
the control software is strictly prohibited.
It is also part of the intended use to conform to the instructions provided in
the User’s Manual.
The manufacturer can in no circumstances be held liable for
damage or consequential damage that occurs as a result of the
non-compliance with the procedures described in the User’s
Manual, the modification of the manufacturer-programmed
welding parameters, or non-intended use. Any such deviation or
modification will cancel any and all warranties under which the
product may be.
Important
3.2 Machine Description
The machine can be used as an in-shop installation, and with anodized alu-
minum components, it is also suited for clean room applications. The ma-
chine enables users to enter the data that are relevant for the welding
process and for the traceability of the welded joint. From the entered welding
parameters, it calculates the applicable forces and temperatures and con-
trols the welding process automatically.
All welding and traceability data are entered either directly on a touchscreen
panel or read from a bar code using a scanning wand. The welding process
in monitored in its entirety and saved to a welding report. All welding reports
can the be printed or transferred to a computer with a suitable pipeline net-
work management software (such as DataWork agru).

3.3 Welding Process Overview
The welding process is performed as follows:
•Pipes are clamped into the frame; depending on the form of the
component to be welded, this may mean that the outer clamps have
to be re-adjusted or that reducer inserts have to be inserted.
•Pipe ends are worked using the pipe facing tool until the machine
tells you that facing is successfully completed.
•Pipe alignment is checked and confirmed on the touchscreen.
•Semi-automatic insertion of the heating element; when inserting it,
the heating element has to be clean.
•After the heating element was inserted, the pipes close in
automatically at the predefined force.
•When the carriages close in, they also align the heating element ex-
actly in-between the pipe butts.
•At the same time, the pipe butts are heated to the predefined tem-
perature.
•When the heat-soaking phase is over, the pipes are moved apart
and the heating element is removed automatically.
•Once the heating element is removed, the pipes close in again au-
tomatically.
•This is followed by a steady force increase until the fusion force is
reached.
•The pipe then cools down at the predefined force.
•After the cooling time is over, the force is automatically removed
from the carriages and the pipe or fitting can be taken out of it.
4 Operation
4.1 Check-out, Turning on, Selecting the Display Language
Place the machine on a level surface and ensure it cannot slide. Sufficient
distance has to be kept to other areas in the workshop, especially to those in
which combustible materials are used, in order for the heating element tem-
perature of up to 500°C (930°F) not to be hazardous.
Depending on the piece that is going to be welded, the outer clamps may
have to be repositioned or removed. To do so, loosen the locking bolts and
either remove the clamp or re-adjust it and secure it by tightening the locking
bolts again.
If the diameter of the pieces to be welded is smaller than the clamp, insert
the reducer inserts. This can be done without using any tools since the
inserts are fastened in the clamps by magnetic attraction.
Pipe clamps and reducer inserts have to be clean or must be
cleaned before welding starts. To insert or remove the inserts, do
not use heavy tools (hammer, wrench). They may damage the
inserts and the magnets.
Important
Important
The surfaces of the heating plate have to be free of grease and
clean, or they have to be cleaned.

another screen allows entering the wall thickness for this material and size.
After the wall thickness, the pressure level per SDR has to be entered in the
next screen. After this, define the key welding parameters for the material
just entered, e.g. 50 mm PE pipe with a wall 2.3 mm thick (SDR 22). To de-
fine them, the unit guides the operator through a series of input screens in
which the following can be entered: joining force, heat-soaking time, cooling
time, plate temperature, force ramp, facing force. Confirm every entered
value by touching “Ok.”

If key data for welding additional, user-
defined materials have already been entered
and saved previously, the unit shows a
screen that resembles Display 8. Use the
arrow keys in the upper area of the screen to
switch back and forth between the various
additional pipe materials currently in memo-
ry. For every pipe material, up to three pipe
diameters can be defined, and for each di-
ameter, up to two wall thicknesses or SDR
values. By touching one of the “Input” but-
tons on this screen, the key parameters for
welding this material can be edited. Touching
the leftmost “Input” button in Display 8 will

Touch the “Edit Parameters” button to change the value of a single welding
parameter in the appropriate data “branch”. Touching this button will let you
access a screen in which the parameter you want to change can be selected
from all the key data that need to be defined. From that screen, an input
screen is accessed in which the value can be changed; then confirm the
change by touching the “Ok” button.
The “Delete Parameters” button can be used to delete that “branch” of the
data “tree,” of which the “Input” button was used to access Display 9. Delet-
ing has to be confirmed in another safety message, and then the key data
for welding the material, from joining force to plate temperature, are deleted
along with the appropriate wall thickness or SDR. If this wall thickness or
SDR is the only one left for the pipe diameter in question, then the diameter
is deleted from the data “tree” too. And if the thus deleted diameter is the
only one left for this pipe material, the entire “tree,” including the material
itself, is deleted.
By touching the “Delete Parameters Completely” button, it is possible to
delete the parameter of all additional, user-defined pipe materials. Here too,
deleting is possible only after cofirming it in a safety message. After deleting
them, only the default materials with which the machine is shipped, remain.

Facing requires three steps:
• Zeroing the facing tool position before
clamping the pipes
• Securing the pipes in the clamps und
determining the facing road
• Facing the butts
First, the machine asks the operator to insert
the facing tool in Position 1 for securing the
pipes. Slide the facing tool in-between the
carriages of the machine so as to place the
position handle into the rest that is labeled
“Pos. 1” at the facing tool support.
Display 11
While the machine automatically performs a zeroing calibration of
the carriage position when it is switched on (including when
power is re-applied after it was switched off using the emergency
off button), it is critical to zero the facing tool prior to the facing
operation proper, failing what it is not possible to ensure a joint of
appropriate quality.
Important
When the facing tool handle is located at Position 1, the machine asks the
operator to close in the carriage (see Display 10). This is done by touching
the “Move on” button and simultaneously holding down the green confirma-
tion push button on the machine front. Then follow the steps the machine
indicates on the screen:determine the facing road, clamp in the pipes, and
move the facing tool to Position 2, the facing position. Remember that every
action that makes the carriage close in or pull away has to be confirmed in
two-hand mode: with the appropriate button on the touchscreen panel and
he confirmation push button on the machine front.t
Before starting the facing process proper, you can determine the facing
road, i.e. the distance that the carriage must travel during facing. To change

the “+” and “–” buttons. The travel length must be a minimum 3 mm. After
you changed the facing road, you have to clamp in the pipes anew. During
facing, the machine displays nominal and actual force along with the effec-
tive facing road so far achieved.
When the pipe butts are faced, the machine shows an end-of-facing mes-
sage (see Display 11). Visually check the pipe butts and, if they are o.k.,
confirm by “Facing Ok”. The machine moves the carriage apart to let you
remove the facing tool. If the result of facing is poor, the process can be
repeated after touching the “Face Ends” button. To face the butts once
again, in most cases the pipes have to be re-adjusted in the clamps.
When pipe facing is successfully finished, it is recommended not
to touch the pipe butts with your bare hands. To avoid fatty layers
on the pipe, use special pipe handling towels.
Info
4.6.2 Checking Pipe Alignment
When the pipe butts are level to satisfaction, it has to be checked if the pipes
align properly to each other or if there is an offset. Similarly as for facing, the
touchscreen tells the welder that this is the next step, and the carriage can
be closed in on the other pipe by the “Start” button. When the pipe butts are
next to each other, two additional buttons appear besides “Cancel”: the
“Face Ends” button and the “Alignment Ok” button.
If the pipes align properly, confirm by touching the “Alignment Ok” button,
and to start the welding process, the machine will tell you to move the car-
riage apart and to close the pipe butts at the far end from the heating ele-
ment with caps; confirm this by “Ok.” Without end caps, the temperature
difference between the welded and the open pipe butt may cause a suction
effect to form, which would then cool the bead, thereby negatively affecting
the quality of the welded joint.
A small offset between the pipes can be readjusted using the adjustment set
screws located at the front of the machine. If the alignment offset is too
large, or if there is too large or too uneven a distance between the pipe
butts, touch the “Face Ends” button to re-adjust the pipes in the clamps and
start the facing process again. In both cases, the machine moves the car-
riages apart to allow for inserting either the heating mirror or the facing tool.
4.6.3 Pre-heating the Pipe Butts and
Inserting the Heating Element
When pipe alignment was checked, the ma-
chine tells the welder first to reposition the
facing tool and heating element assembly to
the right. The carriage rail features a posi-
tioning utility that clicks it into place when it is
in the correct position for inserting the heat-
ing element. As all actions before, this one
has to be confirmed in two-hand mode:
touching the appropriate button on the touch-
screen and holding down the confirmation
push button on the front of the machine.
When the facing/heating assembly is in the
ready-to-heat position, the machine shows
the display asking the welder to insert the
heating plate (see Display 12). Display 1

Then, the welder can either start the stan-
dard welding process that will first launch the
heat-soaking phase, or – by pressing the
“Pre-Heat” button – can pre-heat the pipe
butts before the welding process proper. If he
touches the Pre-Heat button, he has to de-
cide in the next screen whether the left-hand
side, the right-hand side, or both pipe butts
are pre-heated. Touching “Cancel” will return
the machine to the previous screen.
If in the control software, the pre-
heating time is set to 0 seconds,
the machine will skip to the heat-
soaking phase of the regular
welding in all cases.

Using the pre-heating feature is
acceptable only for welding fittings of traditional materials or
fittings to fittings; pre-heating is designed to be used only when
the fitting is securely fastened.
Important
While the welding procedure is starting, with or without pre-heating, the
machine controls and monitors constantly the temperature of the heating
element and the welding force and time.
Nominal values and tolerance ranges are
defined by the key data for the welding
operation previously entered or confirmed. If
a value is not within the applicable tolerance
thresholds, the machine shows an error
message to this effect and the welding
process is aborted.
4.6.4 Heat-Soaking Phase
In the first welding phase, the pipes close in
on the heating element with the defined
welding force and are thereby warmed.
During the entire duration of the heating
phase, they continue to soak heat from the
heating mirror without touching it.
Display 14
On the touchscreen, the welding progress
diagram indicates in which phase the welding currently is (green LED icon).
In case of malfunction, the welding process can be aborted by touching the
“Cancel” button. If the machine detects a
malfunction, the color of the LED icon for the
appopriate phase changes from green to red.
4.6.5 Change-over Phase
At the end of the heat-soaking phase the
carriages are moved apart automatically. The
heating mirror is removed from in-between
the pipes, and the carriages close in again;
both actions occur automatically. The welding
progress diagram on the touchscreen
indicates in which phase the welding
currently is (see Display 15).

The welder has to monitor the change-over and must abort welding by
touching “Cancel”, in case a malfunction occurs.
4.6.6 Joining Phase
In the joining phase (or, fusion phase) the machine increases the applied
force in accordance with the force ramp calculated for the weld. This phase
is also indicated on the touchscreen panel.
4.6.7 Cooling Phase
When the full joining force is reached, the
machine moves on automatically to the cool-
ing phase (see Display 16). The cooling-
down is displayed as a countdown. During
cooling, the applied joining force is constantly
monitored.
4.6.8 End of Welding
After a successful welding operation, which
can also be recognized in the welding
diagram, the applied force is removed from
the pipes, and they can be taken out of the
clamps.

When the welding process is finished, the machine displays an overview
with the applicable welding and traceability data that will be saved to the
report (the screen resembles the one in Display 20), and asks the welder to
remove the pipes and visually check the quality of the joint. In case he finds
that the joint is of poor quality, although the machine did not alert him to any
welding error, he can manually classify the welding result as poor by
touching the “Error” button. This causes the machine to mark the joint as
poor rather than good in the the welding report.
4.7 Aborted Welding Process
All welding-relevant data are constantly
monitored while the welding process is
running. If one or more of the parameters are
out of tolerance and the machine cannot
adjust them, the welding process is aborted
after a given period of time.

The error that made the welding abort is
displayed on the screen (see Display 17).
Additionally, the LED icon in the welding
diagram that belongs to the welding phase
with the malfunction turns red.
The errors listed in the following table can be
displayed on the screen.

adjusted; as long as this error is not cleared, welding or
repeating a welding operation is not possible.
5 Printing Welding Reporting
The machine is equipped with a dual interface that gives you the opportunity
to connect a common desktop printer directly to it or to export the data via a
RS232 cable to a PC with DataWork agru installed.
5.1 The Print Menu and Printing/Transferring Reports
When a data communication cable is connected while the standard data
screen (see Display 5) is showing, the machine displays the print menu.
According to the selection made on this menu, data will be sent to the con-
nected device: to the a printer for print-out or to a PC for further processing
and archiving.

Info
Touch the appropriate button to select print-
ing “All Reports”, printing “By Commission
Number”, or printing “By Date”.
The option “All Reports” causes all the weld-
ing reports stored in system memory to be
printed. While the machine transfers the re-
ports, a countdown indicates how many of
them remain to be printed or transferred.
The options “By Commission Number” and
“By Date” lead the operator to the next
screen in which arrow buttons can be used to
browse through the reports in system memo-
ry to select the desired commission or date
from which reports should be printed or trans-
ferred (see Display 19). The options show the
first available commission number or date, and once the desired one is
found, the selection has to be confirmed by “Ok” to start the transfer to prin-
ter or PC.

If the machine displays a “Printer not Ready”
error message after you touched the “Ok”
button, the printer has to be switched to on-
line mode. Check for potentially damaged
connections from the machine to the printer
or the PC.
If you transfer the data to a PC, make sure
that the correct baud rate and interface type
are set on the PC.
Depending on the printer used,
make sure Auto Carriage Return
and/or Auto Line Feed are
enabled, if necessary, so as to
print the reporting protocol in the
correct format. Display 19
After successful printing, the machine displays a message telling the welder
that printing was o.k.
5.2 Showing Reports in Memory, Reprinting Tags
Using the appropriate option of the configura-
tion menu (see section 4.3), it is possible to
display on the screen the welding reports
saved to memory. A screen like the one in
Display 20 appears. It is similar to the weld-
ing and traceability data overview shown at
the end of each successful welding. opera-
tion. The “Error” field reads “Ok” if no error
occurred, and contains the acronym “PH” (for
„Pre-Heat“) if the welding operation was per-
formed with the pre-heating feature.
Near the left edge of the Report Info screen,
you will find a list of all welding reports cur-
rently in memory. Above this list, the number
