AIR AND/OR WATER COOLED UP/DOWN TORCH
This command (must be inserted in the relevant connector at
Pos. 3, Fig. B) and works as an alternative:
• To the ENCODER - SX knob on the welding machine's DH
control panel. In "synergic" MIG MAG and "manual" MIG
MAG welding processes, by pressing the two right (+) and
left (-) buttons you can regulate the values for the synergic
welding parameters.
• To the ENCODER - DX knob on the welding machine's DH
control panel. In the JOB welding process, by pressing the
two right (+) and left (-) buttons you can scroll the welding
points set previously.
PUSH-PULL TORCH
The push-pull torch makes it possible to improve the alumini-
um wire feed, using the motor on the torch itself. The param-
eters normally regulated using the ENCODER - SX knob on
the welding machine's VS control panel, are now regulated us-
ing the potentiometer on the torch itself, when this torch is on.
The pointing out of any difficulties
and their elimination
The supply line is attributed with the cause of the most com-
mon difficulties. In the case of breakdown, proceed as follows:
1) Check the value of the supply voltage.
2) Check that the power cable is perfectly connected to the
plug and the supply switch.
3) Check that the power fuses are not burned out or loose.
4) Check whether the following are defective:
• The switch that supplies the machine
• The plug socket in the wall
• The generator switch
NOTE: Given the required technical skills necessary for the re-
pair of the generator, in case of breakdown we advise you to
contact skilled personnel or our technical service department.
Replacing the digital interface PCB
Proceed as follows:
• Unscrew the 4 screws fastening the front rack panel.
• Remove both the adjustment knobs.
• Extract wiring connectors from the digital interface PCB.
• Unscrew the nuts and washers on the support.
• Remove the digital interface PCB by lifting it out of its sup-
ports.
• Proceed vice versa to assemble the new digital interface
PCB.
Simple automation
This paragraph describes how to interface the welding machine
with an automatic welding equipment. The connection signs are
marked and available on the "17-pole connector for accessory
/ optional extra connections" (Connector CA - see the "Wiring
diagram" and "Wiring Diagram Legend" paragraphs).
DIGITAL INPUTS
Activating a digital input signal means applying a clean closed
contact to it.
• TORCH BUTTON • Terminals C / D (COM)
When this signal is activated, the welding machine starts the
welding process.
• UP SIGNAL • Terminals D (COM) / F
When this signal is activated, the welding machine increases
the value set beforehand for the welding synergy parameters.
• DOWN SIGNAL • Terminals D (COM) / E
When this signal is activated, the welding machine decreases
the value set beforehand for the welding synergy parameters.
ANALOGUE INPUTS
These inputs must be piloted by a direct voltage that can be
regulated between 0V and 10V.
Their input impedance exceeds 400 kΩ (to enable functionali-
ty of these inputs the voltage between terminals P(-) and R (+)
must exceed 0,5V).
• PARAMETER REGULATION - A • Terminals P(-) / R (+)
By regulating the voltage on this input between 1V and 10V
the welding synergy parameters (WELDING WORKPIECE
THICKNESS, WELDING CURRENT, WIRE SPEED) are reg-
ulated from the minimum to the maximum value.
• PARAMETER REGULATION - V • Terminals P(-) / S (+)
By regulating the voltage on this input between 1V and 10V
the welding parameters (ARC LENGTH, WELDING VOLT-
AGE, ELECTRONIC INDUCTANCE) are regulated from the
minimum to the maximum value.
DIGITAL OUTPUTS
Activating digital output signals means closing a clean contact.
• ARC ON • Terminals T / L
The welding machine activates this signal when it detects
current passing through the welding circuit.
