- the number of the selected program.
- for 2 seconds, the value of the thickness when knob B
is adjusted in pulsed synergic programs.
- within the service functions, the numerical value of the
figure shown on the display G or the messages "On,
OF, Au, A, SP, 0, 1, 2, 4". Read chapter 4 for further
explanations.
- in the memory menu, indicates the program number to
which the memory save or recall refers. Read chapter
5 for further clarification.
R- Key.
Pressing and releasing this key reduces the numerical
value of the display Q.
When pressed together with key O, it allows the user to
select the service and memory functions. (See chapters on
the functions listed)

3 WELDING
3.1 INSTALLATION
Make sure that the wire diameter corresponds to the
diameter indicated on the wire feeder roller, and that the
selected program is compatible with the material and type
of gas. Use wire feeder rollers with a "U"-shaped groove
for aluminium wires, and with a "V"-shaped groove for
other wires.
3.1.1 Connecting the gas hose
The gas cylinder must be equipped with a pressure
regulator and flow gauge.
If the gas cylinder is placed on the cylinder shelf of the
trolley it must be fastened using the chain provided.
Connect the gas hose leaving the rear of the machine to
the pressure regular, only after positioning the cylinder.
The gas flow must be adjusted to approximately 8-10 litres
per minute.
3.2 THE MACHINE IS READY TO WELD
When using the PUSH-PULL P3KP torch, follow the
instructions enclosed.
- Connect the earth clamp to the workpiece.
- Set the switch U to I.
- Choose the program to be used from the list provided
in an envelope on the mobile side panel.
- Display the number corresponding to the program on
display Q using the keys O and R.
- If a pulsed synergic program is used, turn the knob B
until the display Q shows the thickness you will be
using. At the same time the display G shows the
current for the selected thickness.
- If a synergic program is used, make sure that the
indicator of the knobs I and P show the message
"SYNERGIC" and the scale zero, respectively.
- Remove the gas nozzle.
- Unscrew the contact tip.
- Insert the wire in the wire liner of the torch, making
sure that it is inside the roller groove and that the
roller is in the correct position.
- Press the torch trigger to move the wire forward until it
comes out of the torch.
- Caution: keep your face away from the gun tube
assembly while the wire is coming out.
- Screw the contact tip back on, making sure that the
hole diameter is the same as that of the wire used.
- Assemble the gas nozzle.
