2.3.2 Motor-driven generators
These must have a power equal to or greater than 6KVA, and
must not deliver a voltage greater than 260V.
3 INSTALLATION
Make sure that the supply voltage matches the voltage indi-
cated on the specifications plate of the welding machine.
When mounting a plug, make sure it has an adequate capa-
city, and that the yellow/green conductor of the power sup-
ply cable is connected to the earth pin.
The capacity of the overload cutout switch or fuses installed
in series with the power supply must be equivalent to the
absorbed current I1 of the machine.
WARNING! Extension cords of up to 30m must have a
cross-section of at least 2.5 mm2.
3.1 START-UP
Only skilled personnel should install the machine. All con-
nections must be carried out according to current regula-
tions, and in full observance of safety laws (regulation CEI
26-10 - CENELEC HD 427).
3.2 DESCRIPTION OF THE EQUIPMENT
A - Procedure and mode selector switch
This push-button selects the welding procedure
(MMA or TIG) and mode.
The selection changes each time the button is pressed.
The LEDs light alongside the various symbols to display your
choice.
F - LED. MMA welding
This machine can weld all types of covered electrodes*
except for cellulosic.
The welding current is adjusted using the knob H.
E - LED. 2-stage TIG welding (manual). Start
without high frequency.
To light the arc, press the torch trigger and touch the tung-
sten 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 acces-
sory 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/fre-
quency 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 acces-
sory 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 percen-
tage intermittence admissible for the machine, and simulta-
neously 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…
