6) By pushing the WELDING PARAMETERS SELECTION (T3)
key a number of times it is possible to set the various TIG
WELDING PARAMETERS (see the “TIG Welding” paragraph
- WELDING PARAMETERS).
T3
7) To exit welding parameter programming, hold the T3 button
down for about 1 second.
8) Once the all the selections/regulations indicated above have
been made, welding can begin.
9) During the welding process the DISPLAY shows the real Amps
(A) at which the operator is actually welding.
TIG welding - Welding parameters
Press the WELDING PARAMETERS SELECTION Key (T3) a num-
ber of times to set:
L7 L10 L11 L8 L9
T3
L8 PRE-GAS duration (0,05 ÷ 1,00 sec)
WARNING: This CANNOT be programmed when the TIG with
“Lift” type ignition welding processes is active.
L9 SLOPE UP duration (0,0 ÷ 5,0 sec)
L7 PRINCIPAL welding CURRENT I
1
(5 ÷ 200 A)
L10 SLOPE DOWN duration (0,0 ÷ 8,0 sec)
L11 POST GAS duration (1 ÷ 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 (T3) down for about
1 second .
Activating the VRD device
To activate the VRD device, which must be done when the weld-
ing machine is switched off:
1) Use a suitable screwdriver to unscrew the 4 screws that fix
the control panel to the welding machine.
2) Position JUMPER W1 on the DIGITAL INTERFACE BOARD
in the correct position, following the instructions given in Fig-
ure A.
3) Use a suitable screwdriver to tighten the 4 screws that fix the
control panel to the welding machine.
4) Start the welding machine by pushing the switch on the rear
panel to position I .
FIG. A
2000HC23
When the control panel switches on the VRD LED will come on
and will be GREEN, which means that the VRD function is on.
To “deactivate” the VRD device and therefore start to weld, follow
this simple procedure: First touch the workpiece with the elec-
trode, then detach it and ignite the arc within a MAX of
0,3 sec-
onds, otherwise if this time is exceeded the VRD device starts and
prevents welding.
During welding the VRD LED turns RED, which does not indicate
any malfunction on the welding machine, but that the VRD device
has been deactivated to allow welding.
