Button O Wire test.
Allows wire to advance even when no voltage or
current are present. To increase or decrease the
wire speed output from the torch, adjust the knob I.
Button P Test Gas.
When this key is pressed, gas begins to flow out;
press it again to stop the output. If the button is
not pressed again after 30 seconds, the gas output is
interrupted.
Button Q Saving and calling up saved pro-
grams.
To save a current/voltage parameter, simply
press the button Q for at least 5 seconds. The LED R
lights, the display M flashes the message STO, and the
display N flashes the first free number. Use the knob L
to choose the number to which to save the previously
chosen pair of current/voltage values.
Press the button Q again until you hear the save confir-
mation sound, and the number stops flashing. Now,
pressing the key Q briefly exits the function and the LED
R shuts off.
To recall a saved number, simply press the button Q
briefly and call up the number using the knob L. You
may save up to 99 pairs of current/voltage values.
To erase a saved number, press the button Q for at least
5 seconds, turn the knob I until the display M shows the
message DEL, and press the button Q again for another
5 seconds.
A current/voltage parameter may be called up beyond
saving, to change or use it. To call up the parameter,
press the button Q for 3 seconds. Use the knob M to
display the number to recall and show on the display M,
using the knob L, the message rcL. Now simply hold
down the button Q for at least 5 seconds.

SERVICE FUNCTIONS

Press the key V, and hold it down for at least 5 seconds
to enter the submenu. Turn the knob I to select the
function, and use the knob L to select the type of oper-
ation or value.
To return to the normal display, press and immediately
release the key V.
1. Prc Choice of MIG, TIG or MMA mode.
2. AF Activated in MMA welding. It may be adjusted
from 0 to 100%. Adjusts the dynamic characteristic of
the arc, a value adjusted using the knob L.
3. HS Activated in MMA welding. It may be adjusted
from 0 to 100%. Adjusts the overcurrent delivered when
the arc strikes, a value adjusted using the knob L.
4. Syn Activated in MIG welding. Activation indicates
that the welding machine is working in synergic mode.
5. Trg Activated in MIG and TIG welding. Choice
between 2 stage, 4 stage, 3 levels. 2t the machine
begins welding when the torch trigger is pressed, and
stops when released. 4t to begin welding press and
release the torch trigger; to interrupt, you must press
and release it again. 3L this process is active in synergic
14
processes.
Particularly recommended for welding aluminum. Three
currents are available, which may be called up during
welding using the torch start button. The currents and
slope settings are as follows:
SC starting current (Hot Start). May be adjusted from 1
to 200% of the welding current, a value adjusted using
the knob L.
Slo slope. Possible range from 1 to 10 seconds. Defines
the interface time between the first current SC with the
welding current and the second current with the third
current CrC (crater filler current), a value adjusted using
the knob L.
CrC "Crater filler" current. May be adjusted from 1 to
200% of the welding current, a value adjusted using the
knob L.
Welding begins when the torch button is pressed; the
current called up will be the starting current SC. This
current is maintained until the torch trigger is pressed;
when the button is released the first current switches to
the welding current, set with the knob I, and is main-
tained until the torch trigger is pressed again. The next
time the torch trigger is pressed, the welding current
switches to the third current CrC and remains active as
long as the torch trigger is held down. Welding stops
when the button is released.
In the TIG process 3L is different in the way in which the
torch button is pressed.
Welding starts when the welding button is pressed and
immediately released, the recalled current will be the
starting current SC.
This current is kept until the welding button is pressed
and released; at this time the original current connects
to the wedding current, set by means of knob I.
When the welding torch button is pressed and released
again, the welding current connects to the thrid current
CrC and is kept activated until the welding torch button is
pressed and released again; now welding is interrupted.
6. HSA (Automatic Hot Start).
This function is inhibited when the function 3L is active,
and only works with synergic programs.
Once the function enabled using the knob L, the opera-
tor may adjust the level of the starting current SC (Hot
Start). It may be adjusted from 1 to 200% of the welding
current, a value adjusted using the knob L.
It can adjust the duration ScT of this current from 0.1 to
10 seconds.
The Slo time of switching between the SC current and the
welding current may be adjusted from 0.1 to 10 seconds.
7. SP (spot-welding).
This function is inhibited when the function 3L is active.
Selecting the function SPt (spot-welding time) adjusts
the spot welding time from 0.3 to 5 seconds.
Activating the function int (interval time) adjusts the
pause time between one spot-weld and another, and the
