If this function is activated, pressing the torch trigger
causes the following messages to appear in sequence.
- SC (Start current)
Range 1-20 (10-200%)
corresponding to the welding current set using knob B
in the welding programs. Manufacturer setting 13
(130%). Changed using keys O and R.
- Slo (Slope)
Range 0.1-10 sec.,
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 current and the third "crater
filler" current CrC.
- CrC "Crater filler" current
Range 1-20 (10-200%)
corresponding to the welding current set using knob B
in the welding programs. Manufacturer setting 6
(60%). Changed using keys O and R.
How it works in practice:
Welding takes place in automatic mode, thus the
execution times are decided by the operator.
Especially recommended
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 trigger 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.
• PrF (Pre-gas)
Active in all welding programs.
Range 0.0 - 9.9 sec. Setting 0.1 sec. Changed using keys
O and R.
• PoF (post-gas)
Active in all welding programs.
Range 0.1 - 9.9 sec. Setting 3.0 sec. Changed using keys
O and R.
• Acc (Soft Start)
Active only in pulsed synergic welding programs .
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
of the wire speed
manufacturer setting
of the wire speed
for MIG welding
simultaneously until the abbreviation "Au" appears on
display Q.
• bb (Burn-back)
Active in all welding programs.
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
0.5. wire burns.
• PPF (Push Pull Force)
Adjusts the drive torque of the push-pull torch motor.
Serves to make the wire advance in a linear fashion.
Range 9/-9, manufacturer setting 0. Changed using keys
O and R.
5 SAVING AND CALLING UP 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.
of
NOTE: The flashing abbreviation indicates free
programs, those that do not flash are saved
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 number
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
number 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 a saved program, display G shows
its number. When welding begins display G shows the
current, and when it ends LED A lights. All knobs are
disabled.
To see the setting of the service function related to the
saved program, press the key R and hold it down; after 2
sec. the display G shows the first message dSP. Pressing
the torch trigger will display the abbreviations of the
various functions in sequence, and display Q shows the
setting.
To return to welding with a saved program, release the
key R.
To exit saved programs, press the key R and, while
holding it down, briefly press and release the key O.
