EFFECT / RANGE
Preflow Time
0 to 25.0 seconds
Run-In WFS:
Off, 30 to150 in/min.
Start Procedure
0 to 10 seconds
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 and Volts for 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 Non-Synergic CV weld
modes, their adjustment range and function are as follows :
EFFECT / RANGE
Spot Timer:
0 to 120.0 Seconds
Postflow Time
0 to 25.0 seconds
Crater Procedure
(0 TO 10.0 SECONDS)
Burnback:
0 to .25 Seconds
DESCRIPTION
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 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.
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.
