(STT ll MODES ONLY)
DESCRIPTION
Peak Current acts similar to an arc
pinch control. Peak Current sets
the arc length and promotes good
fusion. Higher peak current levels
will cause the arc to broaden
momentarily while increasing arc
length. If set too high, globular
transfer may occur. Setting it too
low may cause instability and wire
stubbing. Best practice is to adjust
for minimum spatter and puddle
agitation.
Background Current controls the
overall heat input in the weld.
Tail out provides additional power
without the molten droplet becom-
ing too large. Increase as neces-
sary to add heat input without
increasing arc length. Often this
results in faster travel speeds.
Note that as tail out increases, the
peak current and/or background
current may need to be reduced.

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.

PREFLOW TIME
0 to 10 seconds
RUN-IN WFS:
Off, 50 to150 in/min.
Start Procedure
FUNCTION
Adjusts the time the gas flows
after the trigger is pulled and
prior to feeding wire.
Run-in sets the wire feed
speed from the time the trigger
is pulled until an arc is estab-
lished.
The Start Procedure is not
commonly used with STT pro-
cedures.

PARAMETER RANGE
Spot Timer:
0 to 120.0 Seconds
Postflow Time:
0 to 25.0 seconds
Crater Procedure
Burnback:
0 to .25 Seconds
FUNCTION
Adjusts the time welding will continue
even if tigger is still pulled. This option
has no effect in 4-Step Trigger Mode.
Adjusts the time that shielding gas
flows after the welding output
turns off.
Crater Procedure is not commonly
used in STT wels procedures.
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.
