with the distribution network operator if necessary,
that the equipment may be connected.
2.2 Controls on the front panel
6
A- LED yellow.
Lights when the thermostat or safety button interrupt
operation of the welding machine.
B- Setting knob.
• Adjusts the welding wire speed when using manual
programs.
In this condition the display
G indicates only the
current during welding.
• When using synergic programs, it allows you to
pre-set the current and adjust during welding. The
current is indicated, in all conditions, by the display
G .
During welding, this current may vary (although only
slightly) based on the thickness of the material and
the manual skill of the operator. It is essential to use
the R key to select the correct welding program so
that the display
G indicates the correct pre-set
current value.
C- LED green.
Signals activation of the spot or dash-welding mode
when lit together with LED
M .
D - Setting knob.
This knob adjusts the spot welding or working time
during dash welding. The duration ranges from 0,3
to 5 seconds.
E - Central adapter
This is where the welding torch is to be connected.
F- Earth socket
Grounding cable socket.
G- 3-Digit display.
This display shows the welding current, which
remains saved after welding; in addition, it briefly
displays the type of material selected when a
program is selected.
With the PUSH-PULL P3KP torch, used with
program N° 2 (manual for AL), the display shows a
value (between 1 and 10) in proportion to the wire
speed.
H - LED green.
Indicates that the welding machine is on.
I- Setting knob.
• Adjusts the welding voltage in manual programs.
• In synergic programs, the indicator of this knob
must be set to the "SYNERGIC " symbol in the
centre of the setting range. Adjusting this knob
allows you to correct the voltage value (arc length).
The operator may need to change the saved values
for various reasons: a non-standard torch may
change the wire movement slightly, the size and
thickness of the workpiece may require minor
corrections from the set values, the operator may
need to change the saved voltage out of habit or
due to his or her own needs.
Obviously, any increases or decreases to the saved
voltage value will be repeated throughout the
synergic curve.
L- LED green.
Indicates that continuous welding mode is
activated.
M- LED green.
Indicates that 2-stage manual dash welding mode is
activated. It lights together with LED
C .
N- Setting knob.
This knob adjusts the pause time between spot
welds. The duration ranges from 0.3 to 5 seconds.
O- Key.
Press this key to light in sequence the LEDs C , L
along with the LEDs M and C .
P- Setting knob.
This knob adjusts the impedance value.
For each program, the optimum value is the
0
position.
The machine automatically sets the correct
impedance value based on the program selected.
The operator may correct the set value: adjusting
the potentiometer t will produce warmer,
less penetrating welds, while vice-versa adjusting
towards - will produce colder and more penetrating
welds.
When welding with a synergic program, adj
or - from the central
0 may require corrections to
the working voltage using the potentiometer I .
Q- 2-Digit display.
This display shows the program number selected
by the
R key.
R- Key.
This key selects the program number, which
appears on the display
Q .
The instructions for deciding which program to use
are provided in a packet inside the mobile side
panel.
S- 10-Pin connector.
This connector must be connected to the 10-pin
male of the PUSH-PULL P3KP torch.
