3. Functional description
Basically, the international and national process guidelines are to be followed !
The plastic pipes are clamped in the clamping devices. Then the front sides of the pipes are cut plane
and parallel by means of the planer and the misalignment of the pipes is checked.
The cleaned and heated heating element is inserted and the pipes are pressed against the heating
element under defined adjusting pressure. This process is called "adjusting".
After the prescribed bead height being reached, pressure is reduced, the heating time begins. The
function of this time is to heat up the pipe ends.
After expiration of the heating time, the slides are opened, the heating element is removed quickly and
the pipes are driven together again. The time gap from the removal of the heating element to joining
the pipes is called change over time.
The pipes are joined under prescribed welding pressure and then cool down under pressure (cooling
time).
The welded joint can be unclamped, the welding process is finished.
Heating element heats
the pipes up to welding
temperature

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. Safety indications
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 situations of danger for persons and the machine, the mains plug has to be unplugged
immediately.
In case of power failure, there may still be pressure in the hydraulic system.
Therefore release pressure if need be.
After completion of the welding work and during breaks the machine has to be switched
off. Further take care that no unauthorized person has access.
Protect the machine from wetness and humidity !
According to VDE 0100, the use on construction sites is only allowed with a power
distributor with a FI-security protective switch.
Check the oil level of the hydraulic system before each starting of the control unit in
order to avoid damages on the pump. The oil level must be between the two marks at the
oil dipstick.
If necessary, add hydraulic oil of the quality HLPD 32.
The heating element surfaces must be clean, especially non greasy, therefore they need
to be cleaned shortly before each welding or in case of dirtiness by means of a fibre-
free paper and a cleaning agent (e.g. PE cleaner or pipe cleaning tissues which are
available at the WIDOS company).
The anti-adhesive coating of the heating element must remain undamaged in the working
area.
Take care that all hydraulic and electric connections are connected.
Make sure that pump and planer are connected in a way that they turn in right-hand
direction.
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.
In addition, take measures against rain, wind and dust.

Screw the reduction inserts with the corresponding diameter into the clamping devices. Pipes with
OD 630 have to be clamped in the basic clamping devices.
If necessary (e.g. for T-pieces) the outer fixed clamping device can be dismantled by unscrewing
the three hexagon socket screws.

5.4. Setting the heating element temperature
As soon as the heating element is connected to the mains (400 V / 16A), it starts heating up to the
desired temperature. Set the temperature with a screw driver at the adjusting knob.
2.2.0
Display: DESIRED temperature + blinking points between the numbers.
The heating element is being heated up, the desired temperature is not yet
reached. This display disappears after short time, followed by three lines.

Display: ACTUAL temperature (without blinking points).
Appears as soon as a temperature of > 170 °C is reached and rises continuously
to DESIRED temperature. The desired temperature is maintained by a certain
pulse-position ratio.
5.5. Welding process
The respectively valid welding prescriptions (ISO / CEN / DVS...) are to be
basically followed.
There is the danger of serious bruising.
On the one hand between the inner clamping devices, on the other hand
between the outer clamping device and the end of the guide bar.
Do wear safety gloves as a protection against burning !
A stop-watch must be available for recording the actual times for heating and cooling.
A welding table must be available from which the parameters for the pipe dimensions to be welded
prescribed by the welding prescriptions may be taken.
Connect the heating element and set the heating element temperature (see chapter 5.4).
Screw in the reduction inserts according to the outside diameter of the pipes to be welded.
Lay the pipes to be welded into the clamping devices, tighten firmly the clamping nuts and align the
pipes with respect to each other. In case of long pipe ends, use WIDOS roller stands for that
purpose.
