the wire. Depending on the setting, there might not be a
ball on the end of the wire that needs to be clipped off
before re-striking an arc. To set the pinch, push and
release button C ( Fig. 4 ) once, and then tur n right
encoder G ( Fig. 4 ) to the desired setting. Differ ent
wire types require different settings. For instance, flux-
cored wire doesn’t need much pinch, while aluminum
wire tends to work well with 30 to 60% pinch,
depending on the alloy and diameter (high pinch rates,
such as more than 75% pinch, can cause burn backs near
or into the contact tip, which causes permanent damage
to the tip). Steel wire typically requires 100% pinch to
get the desired result.

After adjusting burn back and pinch, press and release
button E ( Fig. 4 ) again to get to the next scr een. This
screen ( Fig. 26 ) allows you to adjust the slope down
setting for pulse welding. The slope down feature allows
you to fill the crater at the end of an aluminum weld or
allows you to neatly feather out a stainless steel weld.
On aluminum, set t2 between 3 and 5 seconds by turning
right encoder G ( Fig. 4 ). After you r elease the tr igger ,
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
(the frequency and the sound of the machine changes). If
no slope down is desired, set t2 to 0.1 seconds. The
slope down feature is only available in pulse programs.

Synergic, non-pulse programs have an option to adjust
inductance ( Fig. 27 ). By turning right encoder G ( Fig.
4 ), you can adjust the inductance of the machine.
Typically, this feature is not available on transformer
machines or budget inverter machines. The inductance
feature allows you to set the arc characteristics from
stiff/crisp to soft.
All pulse programs have a feature for Standard Double
Pulse and Manual Double Pulse. To get into the Double
Pulse setup menu, press button E ( Fig. 4 ) as many times
as necessary until the screen in Fig. 28 appears.

Then press button C ( Fig. 4 ) to move the ar row to the
function you intend to select. When you are in the line
you wish to select, press button E ( Fig. 4; the green
check mark ).
If you chose Standard Double Pulse, the next screen will
display your weld settings as shown in Fig. 29 ( the green
arrow in Fig. 29 points to the Standard Double Pulse
symbol).
