Selecting
When this push-button is pressed briefly, the display P
shows the next program number after the one being
worked on. If it has not been saved the message will
flash, otherwise it will remain steady.
Saving
Once the program has been selected, hold for more than
3 seconds to save the data. In confirmation, the program
number on the display P will stop flashing
R - SELECTOR
When this button is pressed, the LEDs light in suc-
cession:
S - LED
Slope up. This is the time in which the cur-
rent, starting from the minimum, reaches
the set current value. (0-10 sec.)
Warning: only those LEDs that refer to the chosen weld-
ing mode will light; i.e., in continuous TIG welding the LED
T, representing the pulse frequency, will not light.
Each LED indicates the parameter that may be adjusted
by means of the knob O while the LED itself is lit. Five
seconds after the last variation, the LED involved will shut
off; the main welding current will be displayed, and the
corresponding LED X lights.
X - LED
Main welding current.
W - LED
Second level of welding or base current.
This current is always a percentage of the
main current.
T - LED
Pulse frequency (0.16-250 Hz)
The peak and base times are equal
U - LED
Slope down. This is the time in which the
current reaches the minimum value and the
arc shuts off. (0-10 sec.)
V - LED
Post gas. Adjusts the time gas flows after welding
ends. (0-30 sec.)
Y - 10-PIN CONNECTOR
The following remote controls are con-
nected to this connector:
a) foot control
b) torch with start button
c) torch with potentiometer
d) torch with up/down, etc...
Z - 1/4 GAS FITTING
This is where the gas hose of the TIG welding
torch is to be connected.
AA - Negative output terminal (-)

GENERAL NOTES
Before using this welding machine, carefully read the
standards CEI 26/9 - CENELEC HD 407 and CEI 26.11 -
CENELEC HD 433. Also make sure the insulation of the
cables, electrode clamps, sockets and plugs are intact,
and that the size and length of the welding cables are
compatible with the current used.
3.4
MMA WELDING (MANUAL METAL ARC)
- This welding machine is suitable for welding all types of
electrodes, with the exception of cellulosic (AWS 6010)*.
- Make sure that the switch AC is in position 0, then con-
nect the welding cables, observing the polarity required
by the manufacturer of the electrodes you will be using;
also connect the clamp of the ground cable to the work-
piece, as close to the weld as possible, making sure that
there is good electrical contact.
- Do NOT touch the torch or electrode clamp simultane-
ously with the earth clamp.
- Turn the machine on using the switch AC.
