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.

POWER FEED

®

10M SINGLE WIRE FEEDER

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 - 25.0 seconds

Run-in WFS:
Off, 30 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 25.0 seconds

Burnback:

0 to .25 Seconds

Crater Procedure

Spot Timer:
0 to 120.0 Seconds

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.

Adjusts the time welding will
continue even if tigger is still
pulled. This option has no
effect in 4-Step Trigger Mode.
