1. Description o the product
1.1. Usage and purpose-oriented Use
The WIDOS 4900 CNC 3.5 has been designed only for heating element butt welding of pipes
and fittings made out of the materials PE, PP, and PVDF with their diameter range going from
OD
min
= 90 mm up to OD
max
= 315 mm in the way as described below.
All use o 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 who are 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!
The control unit is reliable in the use when it is used according to the prescriptions in connection
with a welding machine designed by IDOS.
Also part of the purpose oriented use is
• respecting all the indications of the working instructions and
• performing the inspection and maintenance works.
1.2. Sa ety 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
regulations must be necessarily adhered to.
1.3. Con ormity
The machine corresponds in its construction to the valid recommendations of the European
Community as well as to the according European standard specifications.
The development, manufacturing and mounting of the machine were made very carefully.

3. Functional description
The IDOS CNC 3.5 control unit performs a butt welding process with the plastic welding
machine IDOS 4900 after entering the type of material, the pipe diameter and the pipe wall
thickness.
The welding processes are recorded and can be saved on a SD-card.
The corresponding pipe data are entered manually over the operating field.
Welding with the IDOS 4900 CNC 3.5 works as following:
The plastic pipes are clamped by means of the clamping devices (basic machine) and the pipe
ends are cut plane and parallel by means of the planer.
As soon as the pipes are plane and parallel and the misalignment smaller than 0.1 X pipe wall
thickness you can start welding.
The heating element has to be cleaned and checked before insertion and the desired
temperature prescribed by the DVS must have been reached.
The clamped pipes drive under pressure in direction of the heating element and are heated up
under the defined adjustment pressure (adjusting), the duration of the adjustment is called
adjusting time.
During the adjustment, the bead prescribed by the DVS is performed.
After reaching the prescribed bead height, the control unit automatically switches into the
heating time.
During the heating time, the basic machine is in a pressureless state and the pipe ends are
heated.
After expiration of the heating time, the sledges move apart and the heating element should be
removed as fast as possible.
The time period between the removal of the heating element and the closing of the pipes is called
change over time.
After the maximum time prescribed by the DVS, the pipe ends are driven together and a
continuous welding pressure is built up.
The pipe then cools down under the prescribed welding pressure (cooling time).
After completion of the cooling time, the pressure on the pipe is automatically released and the
welded pipe can be unclamped.
The welding process is completed.
Heating element heats the pipes
up to welding temperature

4.2. EMERGENCY-stop push button
There is an EMERGENCY-Stop push button (see chapter 4.1 No. 9) on the CNC control unit, for
interrupting the working process if the work piece, tools or persons are endangered by the
working pressure.
The devices connected to the plug boxes (e.g. heating element and planer ) are
not disconnected from the main power by the EMERGENCY-Stop and for this
reason dangers due to these devices are still possible.
Turn the main switch off or unplug the main connector!
• The EMERGENCY-Stop push button snaps when it is operated.
• In case the EMERGENCY-Stop push button was pushed, the system is pressure-less and the
sledge can only be moved manually.
• After elimination of the danger, the EMERGENCY-Stop push button must be unlocked again
by turning it in clockwise direction and the functions of buttons <+> and <-> (open and close
the sledge) are possible again.
4.3. Separating device or heating element
There is a tear-off bar mounted between the
movable and the fixed clamping shells on the
basic machine. It prevents the heating element
from sticking to the heated-up pipe ends.
hen inserting the heating element take care
that it lies in the zone of the throat of the tear-
off bar (see arrow).

(Heating element)
There are 3 different states:
• lightening, only interrupted by short switch-off pulses: the heating
element is being heated up, the desired temperature is not yet
reached. The desired and the actual temperature are displayed
alternating on the display of the control.
• blinking: the temperature of the heating element is maintained by a
pulse-position ratio.
• o : the desired temperature has been exceeded, the heating element
is cooled automatically onto desired temperature, or the heating
element is switched off.
Safety micro switch
(Planer)
- The planer starts only when the safety micro switch is pressed.
- Locking device of the planer
On/off-switch
(Planer)
- During the planing process, the planer has to be switched on at the
switch and its corresponding lock button. The planing process is
operated by the CNC control.

5. Starting and operating
The instructions of this chapter are supposed to initiate in the operation of the machine and lead
during the appropriate starting of the machine.
This includes
• the safe operation of the machine
• using all the possible options of the machine
• economic operation of the machine
5.1. Sa ety indications
• The machine should only be operated by initiated and authorized persons.
For the qualification, a plastic welding exam can be taken according to DVS and DVG .
• In situations of danger for persons and the machine, the EMERGENCY-Stop push button or
the main switch have to be activated immediately.
• After completion of the welding work and during breaks, the machine has to be switched off.
Further be sure that no unauthorized person has access.
• According to VDE 0100, the use on construction sites is only allowed with a power distributor
with a FI-safety switch.
Check the oil level of the hydraulic system before each starting of the control unit
in order to avoid damages on the pump.
If necessary, add hydraulic oil of the quality HLPD 32.
The heating element surfaces should be clean, especially non greasy, therefore
they need to be cleaned shortly before each welding or in case of dirtiness by
means of a ibre- ree paper and cleaning agent (e.g. technical pure alcool or
cleaning tissues which are available at the IDOS company).
The anti-adhesive coating of the heating element 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, measures have to be taken:
Use a welding tent or preheat the pipe ends if necessary.

5.2. Replacing the reduction inserts
• Unscrew the mounted reduction inserts.
• Screw the reduction inserts with the corresponding diameter into the clamping devices.
• If necessary (e.g. for T- pieces) the outer fixed clamping device can be dismantled by
unscrewing the three hexagon socket screws.

5.2.1. Using small and large reduction inserts
Small reduction inserts:
• Pipe fittings often have only a short straight surface area on which they can be clamped.
• Fittings mostly need to be clamped in the inner clamping devices with the small reduction
inserts.
• hen fittings are to be welded (bends, T-pieces etc.), the inner small reduction insert can
also be used flush to the inside or to the outside.
