0 to 10 seconds

 

Adjusts the time the gas flows

RUN-IN WFS:

 

Run-in sets the wire feed

Off, 50 to150 in/min.

speed from the time the trigger

 

 

is pulled until an arc is estab-

 

 

lished.

Start Procedure

 

The Start Procedure is not

 

 

commonly used with STT pro-

 

 

cedures.

ARC CONTROL

 

 

 

 

 

 

 

EFFECT / RANGE

 

DESCRIPTION

 

 

 

 

 

 

 

 

 

PEAK CURRENT

 

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 CUR-

 

Background Current controls the

 

 

 

RENT

 

overall heat input in the weld.

 

 

 

 

 

 

 

 

 

TAIL OUT

 

Tail out provides additional power

 

 

 

(STT ll MODES ONLY)

 

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.

PARAMETER RANGE

 

FUNCTION

Spot Timer:

 

Adjusts the time welding will continue

0 to 120.0 Seconds

 

even if tigger is still pulled. This option

 

 

has no effect in 4-Step Trigger Mode.

Postflow Time:

 

Adjusts the time that shielding gas

0 to 25.0 seconds

 

flows after the welding output

 

 

turns off.

 

Crater Procedure

 

Crater Procedure is not commonly

 

 

used in STT wels procedures.

Burnback:

 

The burnback time is the

0 to .25 Seconds

 

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.
