1. Description of t e product
This chapter gives i portant basic infor ation about the product and its prescribed use.
All technical details of the achine are put together as a general arrange ent.
1.1. Usage and purpose-oriented use
The WIDOS 20000 has been designed for the heating ele ent butt welding of pipes and
fittings with a dia eter range fro Ø 1200 up to Ø = 2000 .
It is a achine for construction sites and particularly designed for the usage on-site, as well as
in the workshop.
For this reason, the fra e is kept s all so that it can be used even under difficult conditions
(e.g. ditch).
All use going beyond is not purpose-oriented.
The anufacturer is not responsible for da ages caused by isuse.
The risk is held only by the user.
Also part of the purpose oriented use is
• respecting all the indications of the working instructions and
• perfor ing the inspection and aintenance work.
1.2. Safety measures
In case of wrong use, wrong operation or wrong aintenance, the achine itself or products
standing nearby can be da aged or destroyed.
Persons being in the endangered area ay be injured.
Therefore these working instructions have to be thoroughly read and the corresponding safety
regulations ust be necessarily adhered to.
1.3. Conformity
The achine corresponds in its construction to the valid reco endations of the
European Co unity as well as to the according European standard specifications.
The develop ent, anufacturing and ounting of the achine were ade very
carefully.

Safety rules C apter 2
16.01.12 Working Instructions WIDOS 20000 Page 14 of 98
2.7. Maintenance and inspection, repair
All aintenance and repair work have to be basically perfor ed with the
achine in off position.
During this, the achine has to be secured against unauthorized switching on.
Prescribed aintenance and inspection work should be perfor ed in ti e.
The DVS gives the advice of inspection work after 1 year.
For achines with an especially high usage percentage the testing cycle should
be shortened.
The work should be perfor ed at the WIDOS G bH co pany or by an
authorized partner.
2.8. Dangers w ile andling t e mac ine
The achine WIDOS 20000 is constructed according to the latest technical standard and the
acknowledged technical safety rules. However, dangers for the operator or other persons
standing nearby ay occur. Also aterial da ages are possible.
The achine ay only be used:
• according to the purpose-oriented usage
• in safety technical i peccable status
Disturbances, which may affect the safety of the machine, must be cleared immediately.
2.9. Dangers caused by electric energy
Only skilled persons are allowed to work at electrical appliances!
The electrical equip ent of the achine has to be checked regularly. Loose
connections and da aged cables have to be replaced i ediately.
• If work at alive parts are necessary, a second person has to assist who can disconnect the
achine fro the ains if necessary.
• All electric tools (heating ele ent, planer and aggregate) have to be protected fro rain
and dropping water (if need be use a welding tent).
• According to VDE 0100, the use on construction sites is only allowed with a power
distributor with a FI-safety switch.
2.10. Specific dangers
2.10.1. Danger of stumbling over electric / ydraulic wires
Make sure that no person has to step over the wires.
Lay the wires in such a way that the danger is kept to a ini u .
Do not kink or crush the lines.

Safety rules C apter 2
16.01.12 Working Instructions WIDOS 20000 Page 15 of 98
2.10.2. Dangers caused by t e ydraulics
Syste parts and pressure hoses should be depressurized before beginning of
any repair work. Even if the achine is switched off, pressure ay be in the
hydraulic accu ulator!
There is a danger of injuring the eyes by hydraulic oil squirting out.
• Da aged hydraulic hoses have to be immediately replaced.
• Make a visual inspection of the hydraulic hoses before each work beginning.
• The hydraulic oil is inedible!
2.10.3. Danger of combustion by eating element, reception box and
welding area
You can burn yourself, infla able aterials can be ignited.
The heating ele ent te perature is heated up to ore than 250°C!
• Do not leave the heating ele ent unsupervised.
• Do not touch the surfaces of the heating ele ent.
• Take enough safety distance to infla able aterials.
• Do wear safety gloves.
• Make sure that no person is in the lifting area of the heating ele ent.
• When cleaning the hot heating ele ent with detergents (e.g. with PE cleaner) there is the
danger of infla ation. For this reason, please take care that the infla ation point is
above the actual te perature of the heating ele ent. Do not approach it with any fire
sources (e.g. cigarettes).
2.10.4. Danger of crus ing at clamping tools and guide rails
Heavy injuries can result fro crushing:
- Upon opening / closing the cla ping tools.
- Upon inserting the planer and heating ele ent.
- Upon opening / closing the achine.
- Upon ounting the reducer inserts.
- Upon cla ping the pipes.
- On the one hand between the inner cla ping rings, on the other hand
between the outer cla ping rings and the end of the guiding shaft.
• Do not stand or put your hands between the inner cla ping tools with not yet cla ped
pipes and between the end of the guiding shaft.
• Do not reach between the cla ping rings in case the pipes are yet to be cla ped and in
case you ove the cla ping tools.
• During the installation of the reducer inserts use a lifting device, do not reach between
reducer insert and cla ping tool.
• Do not block the opening and closing of the achine carriages.

3. Functional description
Basically, t e international and national process guidelines are to be
follow ed!
The plastic pipes are cla ped in the cla ping devices.
Then the front sides of the pipes are cut plane and parallel by eans of the planer and the
isalign ent of the pipes is checked.
The cleaned and heated heating ele ent is inserted and the pipes are pressed against the
heating ele ent under defined adjusting pressure. This process is called "adjusting".
After the prescribed bead height being reached, pressure is reduced, the eating time
begins. The function of this ti e is to heat up the pipe ends.
After expiration of the heating ti e, the slides are opened, the heating ele ent is re oved
quickly and the pipes are driven together again.
The ti e gap fro the re oval of the heating ele ent to joining the pipes is called c ange
over time.
The pipes are joined under prescribed welding pressure and then cool down under pressure
(cooling time).

7 Push-button - By pressing the push-button, the otor switches over
to high speed
- Wit out pressing t e button, the otor drives with

8 Valve lever To open the slides. There are 4 different positions:
- To t e left side: slides close.
- in t e middle (usual position): the pressure which is
currently achieved is kept (also by eans of the
built-in hydraulic accu ulator)
- slig tly to t e rig t side (depressurized position):
a possibly existing pressure is released without
Moving the slides. Due to the hydraulic accu ulator,
It takes about 10 s until the pressure is co pletely
released.
- to t e rig t side: slides open

The fuses are ounted on the right side of the aggregate behind the power sockets.
In case a fuse has been activated, thus:
• Eli inate the alfunction.
• Disconnect the aggregate fro the ains afterwards.
• Detach the screws fro the panel with the power sockets.
• Activate the fuse again.
• Mount the panel with the power sockets again.
• Reconnect the aggregate to the power supply.
