PREFLOW TIME	DESCRIPTION
0 - 10 seconds	Adjusts the time that shielding
	gas flows after the trigger is
	pulled and prior to feeding wire.
RUN-IN WFS:
Off, 50 to150 in/min.	Run-in sets the wire feed
	speed from the time the trigger
	is pulled until an arc is estab-
	lished.
Start Procedure	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.

PULSE FREQUENCY: (Low)-10.0 to (High)+10.0

PULSE-ON-PULSE FREQ.MODULATION (Low)-10.0 to (High)+10.0

DESCRIPTION

For Pulse modes, Arc Control changes the pulsing frequency. When the frequency changes, the Power Wave system auto- matically adjusts the back- ground current to maintain a similar heat input into the weld. Low frequencies give more con- trol over the puddle and high frequencies minimize spatter.

For Pulse -On-Pulse modes, Arc controls changes the frequ- ency modulation. The freque- -ncy modulation controls the spacing of the ripples in the weld. Use low values for slow travel speeds and wide welds, and high values for fast travel speeds and narrower welds.

Postflow Time:	Adjusts the time that shielding
0 to 10 seconds	gas flows after the welding out-
	put turns off.
Burnback: 0 to .25	The burnback time is the
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.
Crater Procedure	Crater Procedure controls the
	WFS and Trim 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.
