5) Press the “PRG” PROGRAM key (T2) to confirm.
The WELDING PARAMETERS included, that can be programmed
and changed (by turning the ENCODER knob) in the
SPECIAL
(SPE) configuration, along with those in the STANDARD config-
uration, can be set by pushing the WELDING PARAMETER SE-
LECTION button (T10) successively:
L9 L18 L22
T10
L9 IGNITION CURRENT
2200 AC/DC 3000 AC/DC
5 ÷ 220 A 5 ÷ 300 A
WARNING: This can only be programmed for TIG AC with HF ig-
nition - TIG DC with HF ignition welding processes.
L9 IGNITION TIME duration (t.01 (0,01 sec) -
t.50 (0,50 sec))
WARNING: This can only be programmed when the TIG AC with
HF ignition welding process is active.
WARNING: If the value of these 2 parameters is too low, this could
prejudice ignition.

the 2 STROKES welding mode are used.

the 2 STROKES welding mode are used.
To exit the setting phase, hold the WELDING PARAMETERS SE-
LECTION key (T10) down for about 1 second .
WARNING: These WELDING PARAMETERS are only to be acti-
vated by qualified personnel, or those trained by technicians.
Editing the maximum and minimum
limits for welding parameters
Welding machine in STANDARD (Std) configuration:
In welding processes:
• TIG AC with HF ignition
• TIG DC with HF ignition
The
MATRIX AC/DC
makes it possible to activate modification of
the MAXIMUM AND MINIMUM LIMITS for some WELDING PA-
RAMETERS thereby providing a more expert welder with a more
versatile welding machine.
Proceed as follows:
1) Switch on the welding machine holding down the WELDING
PARAMETERS SELECTION key (T10).
2) Press the WELDING PARAMETERS SELECTION Key (T10)
a number of times to set the limits for the following welding
parameters:
L11
L17 L16 L13 L12
T10
L12 PRE-GAS duration (maximum limit settable from 1,00
to 2,50 sec)
L13 SLOPE UP duration (maximum limit settable from 5,00
to 10,0 sec)
L11 MINIMUM CURRENT for remote controls - minimum
limit settable:
2200 AC/DC 3000 AC/DC
5 ÷ 220 A 5 ÷ 300 A
WARNING: If the minimum limit setting (for the remote control
MINIMUM CURRENT) is greater than or equal to the value for the
PRINCIPAL welding CURRENT
I
1
, you will weld at the PRINCI-
PAL welding CURRENT I
1
, irrespective of the setting you have
chosen for the remote control.
L16 SLOPE DOWN duration (maximum limit settable from
8,00 to 15,0 sec)
L17 POST-GAS duration (maximum limit settable from 10,0
to 25,0 sec)
To exit the setting phase, hold the WELDING PARAMETERS SE-
LECTION key (T10) down for about 1 second . The values set are
now active and welding can begin.
