3. CHARACTERISTICS
3.1 Description of the machine
The welding machines type WM1/LS –WM1/LS-M and WM1/LE produced by PERTICI S.p.A.
are used mainly to weld at different angles, ranging from 180° to 40°.
A) Base plate
The base plate consists of a 3-mm thick sheet bed. (TAV. A1.1)
The elements of the base plate are bent in order to obtain the maximum rigidity and are
assembled by means of an intermittent weld. The control cabinet and all other mechanical
groups composing the machine, are mounted on the base plate by means of commercial bolts
and nuts.
The machine is also supplied complete with four vibration-damping feet, which are fixed to the
lower part of the base plate and permit to place the machine on the floor.

DWG. A1.1
B) Holding surfaces group and profile locking
It is made of aluminium and steel components and of pneumatic components (actuators)
connected by means of commercial bolts and nuts, (DWG. A1.2 and A1.3). The profile holding
surfaces and the locking profile are placed directly on the base plate. The left one is fixed while
the right one is movable and moves horizontally by means of bushings on round section rods
and is pneumatically actuated. On each of them are fixed the reference shoulders for the profile
positioning, where also counterprofiles can be fixed.
The locking plates move vertically by means of plastic bushings on round section rods and are
pneumatically activated by two actuators fixed on two fixed plates, which have been reinforced
against deflection by aluminium tension rods. Actuators are connected to the locking plates by
means of steel and plastic sleeves. The locking plates are electrically isolated from the rest of
the machine in order to permit the correct functioning of our security system, which avoids
squeezing of the operator’s hands.
The profile holding plates and the profile locking plates have a different shape, according to the
various machine types.
Models WM1/LS and WM1/LS-M have removable welding seal limitation blades with the
possibility to put heating rods (electric resistors) inside them, in order to obtain the machine
complete with the optional (heated welding seal limitation blades). It is used, mainly, to weld
PVC profiles coated with an external coloured film.
Model WM1/LE has fixed blades for the limitation of the welding seals, which are obtained
directly in the plates during processing. This type of solution is used above all when welding
only white coloured PVC profiles.

C) - Gruppo posizionatore profili
It is made of aluminium and steel components and of pneumatic components (actuators)
connected by means of commercial bolts and nuts (DWG. A1.4). The device is fixed to the
base plate and is placed under the two profile holding surfaces: During the working cycle a part
of it moves upwards to reach a middle position between and above the two profile holding
surfaces. The positioning plate moves vertically with a lifting/lowering movement, which can be
obtained by means of bushes sliding on round section rods, pneumatically controlled by an
actuator. It can be easily replaced and together with other components permits to modify some
mechanical parameters of the welding process.
DWG. A1.4
D) Group for movement of heating plate for fusion
It consists of aluminium and steel components, as well as pneumatic (actuator) and electric
components (heating plate) (DWG. A1.5). The device for the vertical movement of the heating
plate supports has been fixed on the base plate and placed in the rear left side, just behind the
holding surfaces and profile locking on the fixed side. The heating plate is positioned on the
contrary in a middle position between the working surfaces and the locking plates for the fixed
and for the movable side. The supports of the heating plate are two and are used to obtain a
vertical movement with a long stroke and an horizontal movement with a short stroke. The
lifting/lowering vertical movement is obtained by means of bushes sliding on round section
rods, controlled by a pneumatic actuator. The horizontal movement for plate centering is
obtained by means of linear ball-bushings, which slide always on round section rods.

DWG. A1.5
E) Group for total protection of moving parts and working area
It consists of two main structures, a front and a rear one made of steel sheet, assembled by
means of intermittent weld, which protect the working area and all other dangerous zones of
the machine (DWG. A1.1) . On this safety guard have been placed the following devices: in the
rear fixed part have been made two seats, one hosting the electrovalve-group for the control of
all pneumatic actuators. The other one hosts the two electronic cards, which control all the
machine functions. In the front openable part has been placed a control panel on which has
been fixed a terminal with keyboard and display, plus some control push buttons. Beside there
have been placed a manometer and a pressure regulator, which permit the adjustment and
control of the fusion pressure.
The front openable safety guard has also the aim to facilitate the access to the internal
components in case of maintenance work. This happens to be necessary, above all, to replace
the teflon film on the heating plate, operation that must be carried out many times as the teflon
film wears off very often because of its continuous contact with the profiles.

3.2 Technical features
WM1L/S-M
3.3 Directly functioning components during welding
In order to carry out the welding operation, the welding machines type WM1L/S –WM1L/S-M –
WM1L/E use the following components:
- An aluminium plate heated by an electrical resistor.
- A set of 4 welding seal limitation blades (which can also be heated only for versions
WM1L/S –WM1L/S-M)
3.3.1 Heating plate for fusion
This component is used to heat and fuse the two faces of the profiles to be welded.
The plate thickness is of 14 mm and it is supplied with a 220Vac current. The normal working
temperature ranges between 240° and 260 °C. Take particular care to the electric connections,
which can be damaged because of the continuous movement.
The plate is protected by a film of anti-adherent material (teflon), which has a thickness of
0.125 or 0.15 mm.
This material, as long as it is used, losses its anti-adherent features and the fused profile
material (PVC) starts leaving rests on it. Carry out the cleaning operations following the

Instruction manual for use and maintenance
for WM1L/S WM1L/S-M WM1L/E Single
head machines

indications given in the chapter concerning the maintenance. This material can also, always
because of its wearing, break thus causing an incorrect functioning of the machine. It must be
immediately replaced to obtain a correct functioning and not to damage the fusion plate.
Proceed to the replacement following the instructions given in the chapter concerning the
maintenance operations.
DWG. A1.6
3.3.2 Welding seal limitation blades
The single head welding machines type WM1L are supplied complete with a set of 4 welding
seal limitation blades.
The WM1L/S and WM1L/S-M versions have removable welding seal limitation blades, which
can also as an optional be heated.
The economic version type WM1L/E has fixed welding seal limitation blades, engraved in the
lower profile holding plates and in the upper profile locking plates (the type that can be heated
can never be supplied in this case).
The limitation of the welding seal is adjusted to a standard dimension of 2 mm.
It is possible to give a different adjustment value when ordering (1 mm or 0.2 mm)
In case the optional “heated welding seal limitation blades” has been installed, on the machine
will be also installed 4 cartridge resistors (one for each limitation blade).
These cartridge resistors are supplied by a 230 V and are built with a double insulation safety
system. When executing the welding cycle with a welding seal limitation of 0.2 mm (for coated
or coloured profiles) it is always necessary to use heated blades in order to be able to heat in a
more uniform way, both the profile and the coating.

nylon.
The sturdy design and form of the machines guarantee their safe and damage-free shipment
and storage.
A forklift truck can lift the machines by inserting the forks at the points marked on the machine
packaging (DWG. A1.9).
DWG. A1.9
If the machine is packed in a wooden crate, the fork insertion points are marked on the crate
itself.
Take great care when performing these operations in order to avoid injury to persons and
damage to the machine or property.
4.2 Positioning
The machine must be positioned on a stable floor. Do not install the machine near to areas
containing gas or flammable substances, as the sparks and glowing fragments produced and
scattered may cause explosions or fires.
Position the machine in a place that is easily accessible for the various works and various
hook-ups to:
1) The electric equipment.
2) The compressed air circuit.
Make sure the lighting is adequate for the whole machine
Remove the machine from its packaging and make sure it has incurred no damage during
shipment.
Remove the packaging: a forklift truck can now lift the machine. If transferred by forklift truck,
the forks must be inserted in the lower part of the base plate (DWG. A1.1). Avoid knocks, jolts
and sudden movements when handling the machine.

4.5 Compressed air circuit hook-up
Connection to the line can be made by means of a rubber or Rilsan (Din 74324) hose with a
suitable fitting. We recommend to use a supply hose with an internal diameter of not less than
10 mm.
The working pressure of the user’s net must be, with full load not less than 7/8 bar/atm.
Hook up the line to the slide valve mounted on the FRL air treatment unit and check by moving
the black collar, that the pressure on the gauge reads 7/8 bar/atm.
If necessary, turn the knob on the FRL air treatment unit (DWG. A1.16) to bring the pressure to
the indicated level.
The filter’s function is to filter the dust and moisture out of the air, which may otherwise damage
the valves and pneumatic actuators. When condensate and impurities reach the maximum level
in the container, empty the container by means of the relevant breather.
The approximate air consumption, calculated on the maximum work load is 20.7 lt/work cycle.
During the first few jobs, check that the pressure reading on the gauge does not fall below 6
bar/atm.
4.6 Connection of the electric equipment
Do not hook up the machine to the electricity mains until it has been properly positioned and
fully assembled.
The machine is supplied with the net power supply characteristics requested by the customer.
Before connecting to the mains, check the voltage on the machine ratings plate.
CAUTION:
CHECK THE MACHINE POWER SUPPLY VOLTAGE CAREFULLY.
TO AVOID CAUSING DAMAGE TO THE ELECTRONIC-ELECTROTECHNICAL
COMPONENTS, THE VOLTAGE MUST COMPLY WITH THE FOLLOWING CONDITION:
Va = Vt +/-5% Vt.
Whereby: Va = actual power supply voltage
Vt = machine rating plate voltage
The user's electricity network must comply with IEC 64-8 standards (CENELEC HD 384, IEC
364-4/41).
The network must have:
- a unipotential ground circuit;

-a protective device installed upstream of the machine that is set in such a way as to
guarantee the automatic breaking of the circuit in accordance with the above stated
specifications.
We recommend hooking up with an EEC-standard interlocked plug and socket with safety
fuses, of suitable capacity for the machine power input (see ratings plate).
We recommend the use of fuses suitable for the motor start (AM).
Information about the machine's electrical system are given in Enclosure 3.
The motor has electrical overload protection and cuts out automatically in case of overheating.
Allow the motor to cool and act on the thermal relay SM1 reset button.
5. USE
5.1 Checks before use
The following precautions must be taken each time before using the machine:
- Check that the work surface is free of waste materials and cuttings.
- Check that the protecting teflon of the welding plate has not been damaged or is dirty,
otherwise consult the chapter concerning maintenance for the teflon cleaning and replacement.
