1. Description of product
This chapter gives important basic information about the product and its prescribed use.
All technical details of the machine are put together as a general arrangement.
1.1. Usage and purpose-oriented use
The WIDOS 3511 is exclusively designed for the heating element socket welding of pipes and
fittings out of PE, PP and PVDF with an outside diameter range from 20 mm to 125 mm.
At heating element socket welding, pipe and fitting are welded overlapping.
The heated tool is adjusted to the size of the fitting in a way that a joining pressure is built up at
joining.
Heating element socket joints up to 50 mm pipe diameter can be performed manually.
For diameters as from 63 mm, the use of a welding device is necessary due to the high joining
pressure.
The motion for socket welding is controlled by means of a transport wheel and a toothed rack.
All use of this machine going beyond is not purpose oriented.
The machine is only to be used in a technically perfect condition, as well as purpose oriented,
safety- and danger-conscious in compliance with the working instructions and the relevant
safety regulations (especially the regulations for the prevention of accidents).
The described plastic welding machine may only be operated, maintained and repaired by
persons trained and informed about the dangers.
The manufacturer is not responsible for any damages caused by inexpert handling or
operation.
For personal injuries, material and immaterial damages resulting herefrom, only the user is
responsible!
Prescribed use also means:
following all indications in these working instructions and
performing the inspection and maintenance works.
1.2. Safety measures
In case of wrong use, wrong operation or wrong maintenance, the machine itself or products
standing nearby can be damaged or destroyed.
Persons being in the endangered area may be injured.
Therefore these working instructions have to be thoroughly read and the corresponding safety
advices must be necessarily adhered to.
1.3. Conformity
The machine corresponds in its construction to the valid recommendations of the European
Community as well as to the European standard specifications.
The development, manufacturing and mounting of the machine were made very carefully.

3. Functional description
Basically, the international and national standard specifications are
to be fulfilled.
First of all, the two workpieces to be welded are put into the clamping device, the fitting is
clamped at the stop of the clamping device.
Then the zero offset is effected and the pipe can be clamped in such a way that both
workpieces can be heated up to welding temperature at the same time (heat-up time) with the
help of a socket or spigot-shaped heating element.
After swinging out the heating element (change-over time), the workpieces are joined (cooling
time).
The pipe end, heating element and fitting socket are to match each other in size in such a way
that a joining pressure will build up during joining.
After expiration of the cooling time, the welded joint can be unclamped, the welding process is
finished.

5. Starting and operating
The indications of this chapter are supposed to instruct you in the operation of the machine
and to lead you during the skilled starting of the machine. This includes:
the safe operation of the machine
using all possibilities
economic operation of the machine
5.1. Starting
The machine may only be operated by initiated and authorized persons.
For the qualification, a plastic welding exam can be taken according to DVS
and DVGW.
In danger situations for person and the machine, the mains plug has to be
unplugged immediately.
At the end of the work and during breaks, the machine has to be switched off.
Also take care that no unauthorized person has access to the machine.
Protect the machine from wetness and humidity!
According to VDE 0100, operation on building sites is only allowed with a current
distributor with FI-security protective switch.
The socket and spigot surfaces are to be clean and, above all, free from
grease. Therefore they are to be cleaned with non-fraying paper and
detergent (e.g. PE – cleaning agent or WIDOS pipe cleansing cloths) before
every welding or if they are dirty.
The nonstick coating of the socket and spigot must remain undamaged in the
working area.
Take into account the surrounding conditions:
-The welding may not be performed under direct sun rays influence.
-Use a welding umbrella if necessary.
If the surrounding temperature is under 5°C / 41°F, measures have to be taken:
-Use a welding tent or preheat the pipe ends if necessary.
In addition, take measures against rain, wind and dust.
Take measures against rain, wind and dust.
5.1.1. Assembly of the machine
Detach the clamping handles of the transport case and lift off the case in an upward
direction.
Turn the case upside down with the open space on top and put it on the floor.
Put the case floor together with the machine onto the open case.
Refit the screwed-off heating element handle.
Connect the heating element to the local power supply (230 V / 16 A / 50 Hz) / (110V / 15 A
/ 60 Hz).
Assemble the machine in a way that no unauthorized person may touch the swiveled out
heating element, otherwise install a barrier on site.
The machine can be operated now.

5.2. Welding process
The respectively valid welding prescriptions (ISO / CEN / DVS...) are to
be basically followed.
Do wear safety gloves as protection against burning!
A stop-watch is to be available in order to be able to register the actual times for heating up
and cooling.
Screw the cleaned and fitting socket and spigot which are free from grease onto the heating
element (spigot right-hand / socket left-hand).
Mount the prism clamping tools for the pipe with a corresponding diameter range on the left
side (chapter: 4.4).
Mount the prism clamping tool for the fitting with a corresponding diameter range on the
right side (chapter: 4.5). For clamping the fitting, fitting stops are provided.
A welding table is to be available from which you can read the parameters that are
prescribed by the welding regulations for the pipe dimension to be welded.
The heating element socket / spigot are to be clean and, above all, free from grease.
Therefore they are to be cleaned with non-fraying paper and detergent (e.g. spirit) before
every welding or if they are dirty.
The anti-stick coating of the heating element must remain undamaged in the working area.
In addition, the workpieces (fitting and pipe) to be welded must be clean. If need be, clean
them with detergent and non-fraying paper.
The pipe end is to be chamfered to appr. 15°.
approx. 15°
2-3 mm
Switch on the heating element and adjust the necessary welding temperature at the set
screw at the handle. If the control lamp blinks, the nominal temperature has been reached
and is maintained by means of a defined pulse-pause ratio.
Insert the fitting in the right-hand clamping tool onto the limit stop.
Clamp the fitting by handle.
Support the fitting with support if necessary (chapter: 4.6).

20.08.14 Working instructions WIDOS 3511 Page 20 of 39
Turn the dial until the position “0” locks over the red spot.
Shut the machine until the dial rest against the stop bolt (upper left image) and fix this
position with the clamping lever (8).
Insert the chamfered pipe so that the end face is adjacent to the fitting.
Close the pipe clamping tool and clamp the pipe by handle.
Positioning of different pipes towards the fitting:
Shut the left clamping tool by handle and clamp the pipe tightly.
Release the clamping lever (8) and open the tables.
Swivel the heating element into the machine. The heating element must be immersed into
the recess on the frame in front.
Drive the slides together and the workpieces with minor force onto the heating socket resp.
