MACHINE FUNCTIONALITY BY WELD PROCESS
GMAW (SYNERGIC)
Use the following tables to review how the machine functions (output controls, arc control, Start options and weld
options) for the weld modes listed in the top table.
EFFECT / RANGE
PINCH EFFECT
(-10.0 to +10.0)
DESCRIPTION
Adjust the short circuit current
to create a soft arc, or a force-
ful, digging arc.
EFFECT / RANGE
Preflow Time
0 - 10 seconds
Run-in WFS:
Off, 50 to150 in/min.
Start Procedure
DESCRIPTION
Adjusts the time the gas flows
after the trigger is pulled and
prior to feeding.
Run-In sets the wire feed
speed from the time the trigger
is pulled until an arc is estab-
lished.
The Start Procedure controls
the WFS. Trim at a specified
time at the beginning of the
weld. During the start time, the
machine will ramp up or down
from the Start Procedure to the
preset Welding Procedure.
START OPTIONS
The start Options available in these synergic CV weld
modes, their adjustment range and function are as
follows:
ARC CONTROL
OUTPUT CONTROL KNOBS
EFFECT / RANGE
Postflow Time
0 to 10 seconds
Burnback:
0 to .25 Seconds
Crater Procedure
DESCRIPTION
Adjusts the time that shielding
gas flows after the welding out-
put turns off.
The burnback time is the
amount of time that the weld
output continues after the wire
stops feeding. It prevents the
wire from sticking in the puddle
and prepares the end of the
wire for the next arc start.
Crater Procedure controls the
WFS and volts for a specified
time at the end of the weld after
the trigger is released. During
the Crater time, the machine
will ramp up or down from the
Weld Procedure to the Crater
Procedure.
