It is recommended to keep it separate, and in case of loss,
contact the after-sales assistance.
The generator leaves the factory with the PSS function on
OFF.
3. INSTALLATION
Make sure that the supply voltage matches the voltage
indicated on the specification plate of the welding machine.
The capacity of the overload cut-out switch or fuses installed
in series with the power supply must be equivalent to the
absorbed current I of the machine.

section of at least 2.5 mm
3.1 START-UP
Only skilled personnel should install the machine. All
connections must be carried out according to current
regulations, and in full observance of safety laws (regulation
CEI 26-10 -CENELEC HD 427).
3.2 DESCRIPTION OF THE EQUIPMENT (Pict. 1 and 2).
C – Procedure and mode selector switch
This push-button selects the welding procedure (MMA or
TIG) and mode (2-step, 4-step and spot welding).
The selection changes each time the button is pressed.
The LEDs light next to the various symbols to display your
choice.
LED A – MMA (Manual Metal Arc)
welding.
This machine can melt all types of coated electrodes, except
for cellulose.
With this process the current is adjusted using the knob T,
and it is possible to adjust the "arc force" (LED H) and "hot
start" function (LED F).
LED B – 2-step TIG welding (manual)
When the torch trigger is pressed, the current begins to
increase over the previously set "slope up" time (O LED on),
until it reaches the value set by means of the T knob. When
the trigger is released, the current begins to drop over the
previously set "slope down" time (E1 LED on), until it goes
back to zero.
LED
(automatic)
This program differs from the previous one in that the arc is
both started and extinguished by pressing and releasing the
TIG torch trigger.
LED E – TIG spot-welding LED
(manual)
After selecting the welding current (LED P) and the spot
welding time (LED G1) using the selector switch K, set the
values using the knob T.
This welding mode is to be used only if start-up with high
frequency is selected (LED B1 lit). In this welding mode, the
operator presses the torch trigger, the arc lights, and after the
set spot welding time the arc shuts off automatically. To do
the next spot, you must therefore release the torch trigger
and press it again.
.
D – 4-step TIG
W – 4-step mode selector switch
This push-button selects the welding mode: 4-step with dual
current level, 4-step with with three levels of current and 4-step
SWP special program.
The selection changes each time the button is pressed.
The LEDs light next to the various symbols to display your
choice.
level, (automatic bilevel).
Set the two current levels before lighting the arc:
First level: press the K key until the LED P lights, and adjust the
main current using the knob T.
Second level: press the K key until the LED F1 lights, and
adjust the main current using the knob T.
When the torch trigger is pressed, the current begins to
increase over the previously set "slope up" time (LED O lit), until
it reaches the value set by means of the knob T. The LED P
lights and appears on the display R.
Should it be necessary to reduce the current during welding,
without shutting of 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 F1
will light and P will go off.
To return to the previous main current, press and release the
torch trigger once again. The LED P will light, and the LED F1
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 E1 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
greater than zero, or to the lesser current value of those set.
NOTE: The
RELEASE" refers to a maximum time of 0.5 seconds.
current (automatic trilevel).
To set the three welding currents, proceed as follows:
Press the selector switch K until the LED P lights, then adjust
the maximum current value using the knob T.
Press the selector switch K until the LED F1 lights, then adjust
the intermediate current value using the knob T.
Press the selector switch K until the LED N lights, then adjust
the starting current value using the knob T.
The operating logic is the same as previously described for
welding with dual current level LED V.
welding
program
To light the arc, press the torch trigger and hold it down; the
current begins to increase at a fixed rate. If the torch trigger is
released, the current immediately rises to the welding value
(LED P). To stop welding, press the torch trigger and hold it
down; the current begins to drop at a fixed rate. The current
immediately returns to zero if the trigger is released.
LED A1 - Selector switch for high frequency ignition
and pulsed arc mode, on-off
This push-button selects the ignition type (with high frequency
or by contact) and the continuous or pulsed arc mode. The
selection changes each time the button is pressed.
