When using the machine for TIG welding the operator can
use the torch button to start the weld and the pedal to regu-
late the welding current remotely..
AIR AND/OR WATER-COOLED TORCH UP/ DOWN
The up/down torch replaces the current setting knob on the
front of the welder. Press right (+) and left (-) button to adjust
the active parameter. With this kind of torch, it is also possible
to scroll the saved programmes by pressing the two (+) and
(-) buttons.
Turn the knob to scroll the programmes until an empty and un-
used programme is found.
NOTE: Programme sequences can be created by placing an
empty programme between saved ones.
NOTE: The value shown on the display during welding repre-
sents the effective current output with all types of control.
The digital control unit of the generator is fitted with a control
recognition device which allows it to identify which device is
connected and take action accordingly. To allow the command
recognition device to work correctly, connect (with the machine
switched off) the required accessory to the relative connector
and then switch on the welding machine with the on/off switch.
NOTE: It is not possible to memorize or open programmes
when the remote controls are connected (except for the
torch with UP/DOWN commands).
If a remote control is connected (followed by self-acknowledge-
ment procedure) the machine will automatically return to the
manual-welding phase if it has been pre-set for automatic weld-
ing.
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.
Digital interface PCB replacement
• Unscrew the 4 screws fastening the front rack panel.
• Remove the adjustment knob.
• Extract wiring connectors from digital interface PCB.
• Unscrew small supporting columns.
• Remove digital interface PCB by lifting it out of its supports.
• Proceed vice versa to assemble new digital interface PCB.
