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 PULL 2000 torch, used with program #2 (manual for
AL), the display shows a value (between 1 and 10) in pro-
portion 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 center 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 activa-
ted. 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 adjust 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 towards + will produce
warmer, less penetrating welds, while vice-versa adjusting
towards - will produce colder and more penetrating welds.
When welding with a synergic program, adjusting + 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
Pull 2000 or spool-gun torch.
3.3 CONTROLS ON THE REAR PANEL
T - Gas hose fitting.
U-Switch.
Turns the machine on and off.
4 WELDING
4.1 Installation
Make sure that the wire diameter corresponds to the diame-
ter 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 aluminum
