By pressing the button E ( Fig.4,ref. 9 ) once,
you enter the setup menu (Fig. 24).
The first parameter you can adjust the Pre
Flow time . It is adjustable from 0,1 to 2
seconds.
Press the button
Start Speed regulation .
Normally this function is in AUTO . This is
the optimal parameter calibrated for every
synergic curve.
Press the button
Slope Down Time regulation .
The slope down feature allows you to fill the
crater at the end of the weld or allows you to
neatly feather out a weld. On aluminum, set t2
between 3 and 5 seconds by turning right
( Fig.4,ref. 11 ) to go to
( Fig.4,ref. 11 ) to go to
encoder ( Fig.4,ref. 12 ). After you release the
trigger, the machine still runs for the amount
of time selected, but tapers down
automatically during the slope down time.
The tapering is visual in the arc and is also
audible in the pulse program (the frequency
and the sound of the machine changes). If no
slope down is desired, set t2 to 0.1 seconds.
Press the button
Burn Back regulation .
Normally this function is in AUTO . This is
the optimal parameter calibrated for every
synergic curve.
Burn back adjusts how long the wire sticks
out after you finish welding. AUTO setup
allows the wire to stick out as it normally
does on a classic MIG welder, without any
adjustments.
(Attention: High burn back numbers create
the risk of burning the wire back into the
contact tip ).
Press the button
Post Flow regulation.
