WELDING MODE
The welding power source offers 4 welding modes. Each time
the button is pushed, the welding power source switches to
select the welding mode indicated by the LED that stays lit, in the
following order:
L4 2 STROKES
L5 4 STROKES
L6 SWITCH
L7 SPOT WELDING - DIX ARC COOL
SPOT
L4
L5
L6
L7
L4 2 STROKES
When the torch button is pushed welding begins starting with the
INITIAL CURRENT (if SLOPE UP is selected), while when it is
released welding ends when the FINAL CURRENT is reached
(if SLOPE DOWN is set).
L5 4 STROKES
TIG welding takes place as follows:
•
When the torch button is pushed welding begins at the INITIAL
current.
•
When the torch button is released the SLOPE UP process
is carried out (if applicable) and the current returns to the
PRINCIPAL value
I
1
.
•
When the torch button is pushed the SLOPE DOWN pro-
cess is carried out (if applicable) and the current returns to the
FINAL value.
•
When the button is released the welding SWITCH ends.
L6 SWITCH
When this function has been activated, TIG welding takes place
as follows:
•
When the torch button is pushed welding begins at the INITIAL
current.
•
When the torch button is released the SLOPE UP process
is carried out (if applicable) and the current returns to the
PRINCIPAL value
I
1
.
•
When the SWITCH-button is pressed and released within less
than 1 second the welding current goes to the SWITCH value
(
I
2
), and by repeating this operating you can move between the
two current levels ( I
1
), ( I
2
) an infinite number of times.
•
When the torch button is pushed and held down (for longer than
1 second) you exit the SWITCH, the SLOPE DOWN process is
carried out (if applicable) and the current returns to the FINAL val-
ue. When the torch button is released the welding SWITCH ends.
This welding mode is especially indicated for welding profiles with
different thickness, where continuous current variation is required.
Also, when welding aluminium, it allows you to have a higher initial
current, thereby facilitating pre-heating of the workpiece.
L7 SPOT WELDING - DIX ARC COOL SPOT
This can be used by pushing the torch button to spot weld for a pre-
set period of time (in seconds) at the end of which the arc switches
off automatically. The tack welding function is divided into 3 types:
•
TIG LIFT DC tack welding.
•
TIG HF DC tack welding with a single DIX ARC COOL SPOT
point.
•
TIG HF DC tack welding with a Multi-DIX ARC COOL SPOT
function.
See the relevant paragraphs in the subsequent pages of this manual.
■
DISPLAY
Displays the selections made using the various Keys (with corre-
sponding LED on or flashing) and regulated using the ENCODER
knob.
The button can also be used to view:
L26 AMPERE (CURRENT )
•
When the welding power source is in stand-by, the
Amps (A) set.
•
When the welding power source is welding the real
Amps (A) at which the operator is actually welding.
WARNING: LED L26 switched on and steady.
L27 VOLT (VOLTAGE)
•
The actual VOLTS (V) at the welding clamps (the
value displayed CANNOT BE CHANGED OR
REGULATED).
WARNING: LED L27 switched on and steady.
■
ENCODER knob
This is used to regulate and change the welding
parameters, according to which LED is switched
on and the value shown on the DISPLAY, which
is necessary for the welding power source to work
correctly.
■
SAVE “MEM”
Used to save the parameters for the welding programs.
■
PROGRAM “PRG”
Used to call up welding programs.
When using one of the
2 TIG welding processes, it
makes it possible to set one of the 4 pulsation modes available
on the welding power source, using the relevant button:
L23 SYN PULSE
L24 FAST PULSE
L24 ULTRA FAST PULSE
L25 SLOW PULSE

L23 Synergic pulsations (SYN PULSE)
WARNING:
LED
L23 switched on and steady.
L24 Fast pulsations (FAST PULSE)
WARNING:
LED
L24 switched on and steady.
L24 Ultra fast pulsations (ULTRA FAST PULSE)
WARNING:
LED
L24 switched on and flashing.
L25 Slow pulsations (SLOW PULSE)
WARNING:
LED
L25 switched on and steady.
WARNING: The operator can decide to TIG weld without using
any pulsation mode. If this is the case, the 4 LEDs are switched off.

WELDING PARAMETERS
Each time the button is pushed, the welding power source selects
the next function according to the welding power source configu-
ration, the welding process, the welding mode, etc...
1A - STANDARD CONFIGURATION
Electrode welding (MMA)
When using the electrode welding process, this allows you to select
the following welding parameters, based on which LED is flashing:
L8 HOT START
L9 ARC FORCE
L10 PRINCIPAL welding CURRENT I
