Process key J.
One of the LEDs A, D, or G lights up when selected.
Led A Led D
Mode key K.
One of the LEDs B, C, E, F, H, or I lights up when selected:
Led B "HOT START". Active during MMA welding.
This LED lights up to indicate that the display H1 displays the
time, expressed in hundredths of a second, during which the
welding machine delivers overcurrent to improve electrode
starting. It may be adjusted using the knob K1.
Led C "Arc-Force". Active during MMA welding.
This is a percentage of the welding current. The display H1
displays its value, and the knob K1 adjusts it. This overcurrent
essentially helps the transfer of drops of molten metal.
Led E:
CONTINUOUS TIG welding, started by means of a high
voltage/frequency device.
Led F:
PULSE TIG welding,
voltage/frequency device.
The pulse frequency is adjustable from 0.16 to 500Hz (LED
Q1), the peak current and the base current may be activated
via the LEDs M1 and P1, and are adjustable using the knob
K1.
From a pulse frequency of 0.16 to 1.1Hz, the display E1
alternately shows the peak (main) current and the base
current. The LEDs M1 and P1 light up alternately; above 1.1
Hz the display E1 shows the average of the two currents.
Led H:
CONTINUOUS TIG welding with contact starting (striking).
Led I:
PULSE TIG welding with contact starting (striking). The
operating logic is the same as described for LED F.
Program key R.
One of the LEDs X, W, V, U, T, or S lights up when selected.
Led X, Spot-welding (Manual).
After selecting the welding current (LED M1 and the spot
welding time (LED Q1) using the selector switch M, set the
values using the knob K1.
Led G

This welding mode is only used if continuous welding is
selected and high-frequency start is used (LED E lit). The
operator presses the torch trigger, the arc lights up and shuts
off automatically after the pre-set spot welding time. To do the
next spot, you must release the torch trigger and press it
again. Adjustment range from 0.1 to 30 sec.
When the torch trigger is pressed, the current begins to
increase over the previously set "slope up" time, until it
reaches the value set by means of the knob K1. When the
trigger is released, the current begins to drop over the
previously set "slope down" time, until it returns to zero.
In this position, you may connect the foot controlled accessory

(automatic).
This program differs from the previous one in that the arc is
both started and shut off by pressing and releasing the torch
trigger.
To light the arc, press the torch trigger and hold it down; the
current begins to increase according to a fixed increment rate.
If the torch trigger is released, the current immediately rises to
the welding value (LED M1). To stop welding, press the torch
trigger and hold it down; the current begins to drop according
to a fixed decrement rate. The current immediately returns to
zero if the trigger is released.
three levels of current (automatic).
To set the three welding currents, proceed as follows:
a high
Press the selector switch M until the LED M1 lights up, then
adjust the maximum current value using the knob K1.
Press the selector switch M until the LED P1 lights up, then
adjust the intermediate current value using the knob K1.
Press the selector switch M until the LED T1 lights up, then
adjust the start current value using the knob K1.
When the arc strikes, the current reaches the first setting, LED
T1 lit. The operator may maintain this current for as long as
desired (for example until the part is heated). Pressing and
immediately releasing the torch trigger causes the current to
pass from the first to the second current over the "slope-up"
time (LED S1); the LED M1 lights up once the welding current
has been reached.
Should it be necessary to reduce the current during welding,
without shutting off the arc (for instance when changing the
welding material or working position, moving from horizontal to
upright, etc.), press and immediately release the torch trigger:
the current will switch to the second value selected, the LED
P1 will light up and M1 will go off.
To return to the previous main current, press and release the
torch trigger once again. The LED M1 will light up, and the
LED P1 will go off. To stop welding at any time, simply hold
down the torch trigger for more than 0.7 seconds, then
release. The current begins to fall to zero within the previously
set "slope down" time interval (LED N1 lit).
If you press and immediately release the torch trigger during
the "slope down" phase, you will return to "slope up" if it is set
to a greater value than zero, or to the smallest current value of
those set.
NOTE:
RELEASE" refers to a maximum time of 0.5 seconds.
