E - LED. 2-stage TIG welding (manual). Start
without high frequency.
To light the arc, press the torch trigger and touch the
tungsten electrode to the workpiece, then lift it. This
move must be quick and decisive.
After starting, the current reaches the value set using
knob H.When the trigger is released, the current begins
to drop over the "slope down" time previously set using
knob M, until it returns to zero.
In this position, you may connect the pedal control
accessory ART. 193,
D - LED. 4-stage TIG welding (automatic).
Start without high frequency.
This program differs from the previous one in that the arc
is both started and shut off by pressing and releasing the
torch trigger
C - LED. 2-stage TIG welding (manual). Start
with high frequency.
To light the arc, press the torch trigger: a high voltage/
frequency pilot spark will light the arc.
The operating logic is the same as described for the LED
E. In this position, you may connect the pedal control
accessory ART. 193,
B - LED. 4- stage TIG welding (automatic).
Start with high frequency.
This program differs from the previous one in that the arc
is both started and shut off by pressing and releasing the
torch trigger

G - LED - THERMAL PROTECTION
Lights when the operator exceeds the duty cycle
or percentage intermittence admissible for the machine,
and simultaneously blocks the current output.
NOTE: In this condition the fan continues cooling the
power source.
H - KNOB
Adjusts the welding current.
M - KNOB
Slope down. This is the time in which the
current reaches the minimum value and the
arc shuts off. (0-10 sec.)
L - KNOB
Post gas. Adjusts the time gas flows after
welding ends. (0-30 sec.)
I - 10-PIN CONNECTOR
The following remote controls are connected
to this connector:
a) foot control
b) torch with start button
c) torch with up/down, etc...
O - 1/4 GAS FITTING
This is where the gas hose of the TIG welding torch
is to be connected.
