4-17. Synergic Pulsed MIG Welding Advanced Settings
To change all values list, unit must be
MENU FULL. To set unit to MENU FULL,
proceed as follows:
Press P2 to enter SET UP menu.
Select MENU FULL on D1 and D2 (see
Section 4-10).
Wire Feed Speed Unit (only in MENU
FULL)
Use E1 to change D1 to UNIT.
D2 value is default setting of mpm (meter
per minute).
Use E2 to change D2 to desired setting, ei-
ther IPM (inches per minute) or CUR (weld-
ing current in amperes).
Setting Pre−Gas (only in MENU FULL)
Use E1 to change D1 to PREG.
D2 value is default setting of 0.0 s (range is
0.0 s to 10.0 s).
Use E2 to change D2 value.
Setting Post−Gas (only in MENU FULL)
Use E1 to change D1 to POSG.
D2 value is default setting of 0.1 s (range is
0.0 s to 10.0 s).
Use E2 to change D2 value.
Setting BurnBack
Use E1 to change D1 to BURN.
D2 value is default setting of Auto (range is
1% to 200%).
. Auto is a setting below 1% that pro-
vides an automatic backback time.
Use E2 to change D2 value.
3 Level Trigger Mode
Use E1 to change D1 to 3LS1.
D2 value is default setting of 130% (range
is 20% to 200%).
Use E2 to change D2 value.
Use E1 to change D1 to 3LS2.
D2 value is default setting of 80% (range is
20% to 200%).
Use E2 to change D2 value.
Use E1 to change D1 to 3LRT (only in
MENU FULL).
D2 value is default setting of 0.5 s (range is
0.1 s to 0.5 s).
Setting Cooler Status
. Be sure that cooler is turned on for wa-
ter-cooled torch to prevent damage to
torch components.
Use E1 to change D1 to W−UN.
D2 value is default setting of ON.
Use E2 to change D2 value to OFF, if appli-
cable.
Setting Synergic Double Pulsed MIG
Welding
Some metals weld better using the Synerg-
ic Pulsed Welding process due to the
unique pulsing of the welding arc. Heat
generated in the workpiece is generally
lower and the arc characteristics produce
a better weld bead appearance especially
on aluminum. The Synergic Double Pulsed
MIG process allows control all parameters
to produce high quality welds on aluminum.
. Incorrect settings in Synergic Double
Pulsed Welding process can result in
a program with undesirable weld char-
acteristics. Setup should only be used
by operators familiar with various
welding processes and parameters. In
some cases, standard Synergic
Pulsed MIG welding can produce bet-
ter welds.
Use E1 to change D1 to DP.
D2 value is default setting of OFF.
Use E2 to change D2 value to ON. This set-
ting will enable or disable Double Pulse in
Synergic Pulsed MIG welding.
Use E1 to change D1 to DPFR.
D2 value is default setting of OFF.
Use E2 to change D2 value.
The range of this setting is 0.1 H to 5.0 H.
This setting allows changing double pulse
frequency in hertz (cycles per second). A
recommended frequency is approximately
1 hertz. OFF means double pulse is off.
Use E1 to change D1 to DPDC.
D2 value is default setting of 50%.
Use E2 to change D2 value.
The range of this setting is 25% to 75%.
This setting allows changing the time that
the pulse is at high output. A lower setting
will produce less heating at the welding
puddle.
Use E1 to change D1 to DPOF.
D2 value is default setting of 1.0M.
Use E2 to change D2 value.
The range of this setting is 0.2 M to 2.0 M.
This setting allows changing the difference
in high wire feed speed and low wire feed
speed from the main wire feed speed set-
ting. For example, if main wire feed speed
is set at 5 M and DPOF setting in D2 is 1.0
M, the wire feed speed will change be-
tween 4 m/min and 6 m/min. A recom-
mended setting is 1.0 M or less.
Use E1 to change D1 to DPAR.
D2 value is default setting of 0.0 T.
Use E2 to change D2 value.
The range of this setting is −5.0 T to 5.0 T.
This setting allows changing the high end
of trim in double pulse and the main setting
for trim will be the low end. A higher DPAR
setting will produce a longer and hotter arc
and lower setting will produce a shorter and
cooler arc.
