2START-UP
After the machine is electrically and pneumatically powered on, conduct a careful visual inspection
of the entire machine and make sure there are no objects left on top of it, that no people or materials
obstruct its normal operation. The presence of power supply will be indicated by a warning light of
the Operating voltage on the control panel.
Check that all the safety devices of the machine are enabled; if necessary, reset them, and in
particular check for:
Emergency stop is unlocked.
Proper operation of the safety barriers, no guards are removed.
Protection guards.
After that, the machine may be operated.
Press the button Enable to activate the machine. This operation must be carried out both at
power up and after an emergency stop.
Data setting
 Fusion timing - Adjust the profile heating and melting time, i.e. the time that the profiles
remain in contact with the heating plate. Set to 15 to 30 sec, based on the profile type.
 Welding timing - Adjust the time that the profiles are held together for welding. Set to 15-
30 sec, according to the type of profile.
Enable the resistances
 Temperature of the heating plate (about 240°-250°). Set between 230°C and 250°C.
Adjust the pressure of the workpiece table. This is the pressure with which profiles are
moved together, after heating, during the welding step.
Adjust the pressure of the pressers. This is the pressure with which profiles are pressed
together by workpiece table pressers during welding, when the pneumatic system is
switched to high pressure.

3USING THE MACHINE - WELDING
Press the button Locater Plate; you will see the shaped positioner that
supports PVC profiles to be welded.
Place the first profile on the right side of the machine against the locater Plate;
Press the RH Clamp Cylinder Button that blocks the profile on the right side;
releasing within about 4 seconds (the time during which the button is flashing), the
presser goes back. This allows the operator, in case he had committed a positioning
error or if he find his hand under the pressurer, to remove the pressure by simply
releasing the button. When the indicator stops blinking and turns off, the pressure on
the piece will remain constant. During this step, the machine operates at a low pressure
(2 bars).
Place the second profile on the left side of the machine against the shaped positioner;
Press the LH Clamp Cylinder Button that blocks the profile on the left side;
releasing within about 4 seconds (the time during which the button is flashing), the
presser goes back. This allows the operator, in case he had committed a positioning
error or if he find his hand under the pressurer, to remove the pressure by simply
releasing the button. When the indicator stops blinking and turns off, the pressure on
the piece will remain constant. During this step, the machine operates at a low pressure
(2 bars).
Press simultaneously the buttons Start Cylce and Locater Plate with the
two hands. The welding cycle will start. The light indicator
High pressure is on. This
indicates that the pneumatic circuit has gone from low to high pressure. The shaped
positioner lifts automatically, the heating plate appears; once the heating operation is
finished, the plate falls inside the machine and the profiles will be automatically moved
to the welding step. The buttons must be kept pressed until they are switched off or

until the plate is finished heating the profiles and is returned to the rest position. If one
of the two keys, or both, are released before the end of welding, the cycle will be
interrupted and the welding machine will return to the rest position. This allows the
operator to interrupt the cycle in case of error or emergency.
Press the button Welding Plate to change the temperature. Before this operation, make
sure you have switched off the heating elements and that the plate has cooled completely.
- Adjusting temperature setting on controller; press SET and change it to ON.
doing this you will be able to freely change the temperature pressing the up and down arrows.
4WARNINGS
Welding reduces the length of profiles from 3 to 5 mm. Make of test samples and determine
whether you need to cut longer profiles.
Pay close attention to the installation of counterblocks; their correct placement is one of the
factors that most affects the welding result. The manufacturer does not provide
counterblocks but can provide a set of counterblocks connections.
Do not weld profiles when the ambient temperature is below 18-20°C.
Make sure the cloth that covers the heating plate is intact and clean; replace it if damaged.
The heating plate temperature must be constant over the entire surface; check it periodically
with a precision thermometer, making sure that the measured temperature matches the one
set.
The accuracy of cutting angles of the profiles to be welded is extremely important; imprecise
cuts will affect the welding result.
For all non-coated profiles, the weld seam is 2 mm; this value ensures the best welding
sealing;
For coated profiles, the weld seam is 0.2 mm; this reduces the curb line of the subsequent
cleaning.
Carry out tests to determine the different welding parameters; set the temperature controller
of the heating plate at 240°C and perform a welding cycle. After reviewing the result, raise
the temperature if the profile shows little resistance during the burst test. Lower the
temperature if the weld curb begins to turn yellowed.
5NORMAL SHUT-DOWN
Is activated by the Stop button on the general panel; stops the machine.
