drop to the current set using knob B (welding) in the
time set with Slo (in this specific instance, 0.5 sec).
We recommended this function for spot welding
sheet aluminium.
If this function is not activated, pressing the torch trigger
activates the function:
• 3L ((three llevels)
Active iin p
pulsed ssynergic ccurves
Caution: IIf tthe ffunction 33L iis aactivated, tthe ffunction H

is aautomatically nnot iincluded.
Display Q shows the message OF =OFF = Off
Pressing the key O causes the display Q to show the
message On = Active.
If this function is activated, pressing the torch trigger
causes the following messages to appear in sequence.
-S
SC ((Start ccurrent)
Range 1-20 (10-200%) of the wire speed correspond-
ing to the welding current set using knob B in the
welding programs. Manufacturer setting 13 (130%).
Changed using keys O and R.
-S
Slo ((Slope)
Range 0.1-10 sec., manufacturer setting 0.5.
Changed using keys O and R.
Defines the interface time between the first current
(SC) and the welding current set using the knob B in
the welding programs, and between the welding cur-
rent and the third "crater filler" current CrC.
-C
CrC ""Crater ffiller" ccurrent
Range 1-20 (10-200%) of the wire speed correspond-
ing to the welding current set using knob B in the
welding programs. Manufacturer setting 6 (60%).
Changed using keys O and R.
How iit w
works iin p
practice:
Welding takes place in automatic mode, thus the exe-
cution times are decided by the operator.
Especially recommended for MIG welding of aluminium.
Three currents are available, which may be called up
during welding using the torch start button.
Welding begins when the torch button is pressed. The
welding current used will be the one set using the SC
function (in this specific instance 13 =130%). This
current will be kept for as long as the torch trigger is
held down; when released, the first current changes
to the welding current, set with the knob B, within the
time established by the Slo function (in this specific
instance, 0.5 sec.), and will be kept until the torch
trigger is pressed again. The next time the torch trig-
ger is pressed, the welding current will switch to the
third or "crater-filler" current, set with the function
CrC (in this specific instance, 6 = 60%), in the time
established by the function Slo (in this specific
instance, 0.5 sec), and will be maintained as long as
the torch trigger is held down. Welding stops when
the trigger is released.
If this function is not activated, pressing the torch trigger
activates the next function.

Range Auto - 1-99%
This is the wire speed, expressed as a percentage of the
speed set for the welding, before the wire touches the
workpiece.
Note: This adjustment is important in order to always
achieve good starts.
Manufacturer setting "Au" automatic.
Changed using keys O and R. If, after changing, you wish
to return to the manufacturer setting, press keys O and R
simultaneously until the abbreviation "Au" appears on
display Q.

Range 00 - 99. Manufacturer setting "Au" automatic.
Serves to adjust the length of the wire leaving the gas
nozzle after welding. The higher the number, the more the
wire burns.
• PPF ((Push P
Pull FForce)
Adjusts the drive torque of the push-pull torch motor.
Serves to make the wire advance in a linear fashion.

MEMORIES
Ten memory slots are available, from P01 to P10.
• To save, weld a small section using the parameters you
wish to save, then:
-Press the key R and, holding it down, press the key
O until the flashing abbreviation P01 appears on the
display G, then release the buttons.
NOTE: TThe fflashing aabbreviation iindicates ffree p
pro-
grams, tthose tthat d
do nnot fflash aare ssaved p
programs.
Display Q indicates the number of the program to
which that saved welding program refers.
-Use the keys O and R to choose the program num-
ber to save, then press the key O until the program
abbreviation no longer flashes.
-Release the key O to exit saving.
-Should you intend to overwrite a program, when the
button O is held down for longer than 3 sec, the num-
ber starts flashing, then returns to steady mode to
signal overwriting.
Overwriting must take place while the display G
shows the program number (5 sec).
• To call up a saved program, repeat the same steps
described above
(keys R and O held down until the abbreviation PXX
appears); the last program saved appears. Five seconds
after the last time the keys R and O are pressed, the
machine is ready to weld.
Before welding with aa ssaved p
program, display G shows its
number. When welding begins display G shows the cur-
