TIG “AC and DC” welding
- Welding parameters
• The
MATRIX AC/DC
can be configured in the following
2
ways:
• STANDARD (Std) configuration.
• SPECIAL (SPE) configuration.
STANDARD CONFIGURATION (Std)
When it leaves the factory the welding machine is normally con-
figured in STANDARD (Std) mode.
To check the configuration, carry out the following operations:
1) When the welding machine is off, push and hold the “PRG”
PROGRAM key down (T2).
2) Start the welding machine by turning the power supply switch
to position I .
3) The DISPLAY (D) shows the following message: Std (welder
configured in STANDARD mode).

The WELDING PARAMETERS included, programmable, and that
can be edited (by turning the ENCODER key) in a STANDARD
(Std) configuration can be broken down into 3 different sub-groups:
1 - “BASIC” WELDING PARAMETERS
Press the WELDING PARAMETERS SELECTION Key (T10) a
number of times to set:
L18 L11 L22
L17 L16 L13 L12
T10
L12 PRE-GAS duration (0,05 ÷ 1,00 sec)
WARNING: This CANNOT be programmed when the TIG DC with
“Lift” type ignition welding processes is active.

WARNING: This can only be programmed when 4 STROKES or
CYCLE welding mode is activated.
L17 POST GAS duration (0,5 ÷ 25,0 sec)
WARNING: When the post-gas LED flashes and the LED I
1
is on
at the same time, this means that the welding machine is in the
post-gas stage.
To exit the setting phase, hold the WELDING PARAMETERS SE-
LECTION key (T10) down for about 1 second .
2 - WELDING PARAMETERS with
PULSE mode active:
Pulsed TIG welding allows greater control of the arc and better de-
formation of the material.
The MATRIX AC/DC can be used for TIG AC and DC pulsed weld-
ing in 4 different modes:
• SLOW PULSE
• FAST PULSE
• ULTRA FAST PULSE
• SYN PULSE
WARNING: Pulsation is deactivated automatically for the duration
of the INITIAL and FINAL current.
2A) SLOW PULSE
TIG pulse welding with manual setting of parameters.
WARNING:This can only be programmed when the 3 TIG weld-
ing processes are used.
Press the PULSE key (T5) until the requited pulsation
is active.
Press the WELDING PARAMETERS SELECTION Key
(T10) a number of times to set the following (in addi-
tion to the WELDING PARAMETERS defined as be-
ing “BASIC”):
L20 L21
L15 L14
