2.8.1. Danger of stumbling over electric wires
Make sure that nobody has to step over the cable to the heating element.
2.8.2. Danger of combustion by heating element and welding area
You can burn parts of your body and inflammable materials can ignite!
The heating element can be heated up to more than 250° C!
Do not leave the machine with the heated heating element unattended.
Do not touch the surface of the heating element.
Take enough safety distance to inflammable materials.
Do wear safety gloves.
Pay attention that nobody is in the area of the heating element.
While cleaning the heating element with cleaning agents (e.g. with PE-cleaning agent) there
is the danger of igniting. Therefore pay attention that the flashpoint is smaller than the
temperature of the heating element, do not put inflammable materials next to it (e.g.
cigarette).

3. Functional description
All international and national process guidelines are to be basically
followed!
By using the clamping beams the plastic sheets are clamped by pneumatic cylinder and foot
valve.
Afterwards the position of the sheets are checked and if necessary changed.
Now the heating element is slewed in and the sheets are pressed on the heating element at a
defined pressure. This process is called "adjusting".
The applied power can be seen on the pressure gauge you find on the machine.
Having reached the mandatory bead height the pressure is reduced, the heating time begins.
This time is used to reach the welding temperature at the sheet ends.
After the ending of the heating-up, the tables drive apart, the heating element quickly slews
out of the machine and the tables drive together again, we call this change-over time.
The sheets are joined at the needed welding pressure and cool down under pressure
(cooling time).
The welding joint can be clamped out and the welding process is completed.

4.2. How to clamp the sheet
Insert and clamp each sheet between clamping beams and basic plate.
In order to clamp, release the clamping beam by the corresponding foot switch.
Insert the plastic sheet onto the basic plate and align the sheet in a way that the welding
surface overlaps to the inside in rectangular manner and at a short distance.
The clamping beams are flush on one side
and feature a ledge on the opposite side.
The beams may be used on both sides.
While welding sheets, especially thin sheets,
you must use the ledge side on the inside;
then the sheets are clamped close to the
weld.
While welding angles you must insert the
beam flush to the center in order that the
vertical sheet may be supported.
4.2.1. How to change the clamping beams
Detach the threaded bolts at the rear cylinder and disconnect the pneumatic hoses from the
cylinder (left image).
Slightly lift the clamping beams at the front and swing the piston rods forwards out (right
image).

Remove the clamping beams, disassemble each handle and mount it on the opposite side.
Insert the beams back again into the machine; left beam to the right and right beam to the
left.
Fix both rear cylinders and clamping beams using the threaded bolts.
Connect the hydraulic hoses to the cylinder; the blue hose at the top and black one at the
bottom.
Lift the clamping beam at the front and swing the piston rods in
again; the beam must rest on the washer afterwards.
4.3. How to clamp sheets for angle welding
You may weld an angle out of two plastic sheets on the WIDOS PSM 20.
The horizontal sheet of 10 - 20 mm is clamped onto the left side (chapter:
4.2).
The vertical sheet, from 5 mm thickness, is clamped onto the right side.
First clamp the right beam (without sheet) tightly onto the right attachment.
Put the vertical sheet onto the interior of the right clamping beam onto the ledge and fix sheet
e.g. with screw clamps.

10.12.2013 Working instructions WIDOS PSM 20 Page 18 of 31
Lift the heating element and fix it additionally in the height by
a spacer.
The machine features (optional) spacers for a sheet
thickness of 10 / 15 / 20 mm of the horizontal sheet.
Always align spacer and sheet thickness to each other in
order that the vertical sheet is only heated at the welding
area.
Spacer height 65 mm for sheet thickness of 10 mm
Spacer height 70 mm for sheet thickness of 15 mm
Spacer height 75 mm for sheet thickness of 20 mm
Remove the spacer after heating, otherwise the heating
element cannot swing downwards.
4.4. How to open the clamping beam to remove the pieces
Lift the clamping beam at the front and swing the piston rods forwards out.
Now remove the angle or the pipe forwards out of the machine.
Since the clamping beam is very heavy, you may insert a spacer between
clamping beam and support in order to remove a welding piece.
The spacer may have a height of max. 60 mm, otherwise it may damage the
rear part of the piston rod!
Lift the clamping beam at the front, remove the space and swing the
piston rod in again; the beam must rest on the washer afterwards.
Insert the spacer here into the base
frame of the lifted heating element.

4.5. How to weld a pipe out of sheets
The PSM 20 allows you to weld a plastic sheet together to get a pipe.
For this purpose clamp the plastic sheet on one side.
Now bend the sheet and fix it on the opposite side.
You may harm yourself! As soon as the tension reduces, the bent sheet will
resile into its original position.
It is recommended to secure the bent and clamped sheet additionally by
clamping belts.
After welding open both clamping beams (chapter: 4.4) and remove the welded pipe
forwards out of the machine.
4.6. Service unit
Activate valve by turning.
The service unit (LFR-1/8-D-MINI-KC) regulates the fed compressed air onto the adjusted
working pressure and compensates pressure fluctuations. It clears the compressed air from
dirt particles and condensation water. It is not intended for the use of other media (liquids or
gases).
In order to adjust the regulator:
slowly ventilate device.
pull the pressure regulator button for the unlocking upwards (away from housing).
Turn the pressure regulator button until the desired pressure is shown on the pressure
gauge. The input pressure must be at least 1 bar larger than the output pressure.
Press the pressure regulator button downwards (towards the housing). Thereby, it is
secured against unintentional twisting.

5. Starting and operating
The instructions of this chapter are supposed to guide you in the operation of the machine and
lead you 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. Starting
Having removed the packaging material the attached guide pulleys have to be mounted on
the left side and the trestle pulleys on the right side of the basic cradle.
Connect the hydraulic with mains (230 V / 50 Hz / 16 A).
Connect the heating element with mains (230 V / 50 Hz / 16 A).
Connect one pneumatic hose to the local compressed air supply (6 – 8 bar) and to the
connector of the service unit (chapter: 4.4)
The machine only has to be introduced and used by skilled persons.
For their qualification they must pass an exam of plastic welding according to
DVS and DVGW.
Before starting the hydraulic check the level of the oil in order to avoid damages
on the pump.
If necessary add hydraulic oil of the quality HLPD 32 (chapter: 7.4).
In dangerous situations for man and machine you have to immediately disconnect the
machine from the mains plug.
Having finished the welding work and during intervals you have to turn off the heating
element. Furthermore you have to control that no unauthorized person can use the
machine.
Protect machine against humidity!
The use on building sites is only permitted when respecting VDE 0100 and using current
distribution with FI-safety-switch.
Carefully install electric cables (danger of stumbling)!
Pay attention to environmental conditions:
The welding process may not take place in case of direct insolation.
If local temperature is under 5° C the following measures have to be taken:
if necessary heat-up sheet ends.
Take measures against rain, wind and dust.
