S5: SET-UP/parameters key
Permits access to the SET-UP and welding parameter values.
When pressed at switch-on, it permits access to the set-up
parameters while the software version appears on D1.
If pressed after the end of the welder switch-on procedure, it
selects in sequence the welding parameters presented in the
graph G1 with value shown by D1 and variable with E1.

l1: Ignition switch
Controls electric ignition of welder.
It has two positions: "O" off and "l" on.
WARNING
*
With l1 set to the position "l" on, the welder is opera-
tional and voltage is present between the positive (+)
and negative sockets (-) on the electrode. In TIG the wel-
der requires the pedal or torch button start for voltage
to be present between the sockets (+) and (-).
*
When the welder is connected to the mains, even with
l1 set to the "O" position some of the internal parts will
be live. Carefully follow the warnings given in this
manual.

Set-up parameters
When S5 is pressed after switch-on, the set-up menu is acces-
sed (confirmed by a central "0" on the display D1) while the
software version appears on D1. Via E1 the set-up line is
varied, via S5 the required line is confirmed, via E1 the value
is varied, via S5 the value is confirmed and so on.

6 Min current value in TIG EXT
7 Max current value in TIG EXT welding
9 Reset of all parameters
14 Pulsed TIG basic l setting mode (0=in amps, 1=percenta-
ge of peak l)(default=0)
23 TIMER mode setting
(23 = 0: 2-stage mode, 23 ≠ 0: welding time)
99 Reset of all parameters
If we enter lines "9" and "99" and press S5, all the
set-up parameters will go to the factory-set values.
To quit set-up and save the set values, return to
line 0 and press S5.
