ARC CONTROL
PULSE	DESCRIPTION
FREQUENCY:
(Low)-10.0 to	For Pulse	modes, A rc Control
(High)+10.0	changes the pulsing frequency.
	When the frequency changes,
	the Power Wave system auto-
	matically	adjusts the back -
	ground current t o maintain a
	similar heat input into the weld.
	Low frequencies give more con-
	trol over the puddle and high
PULSE-ON-PULSE	frequencies minimize spatter.
	For Pulse -On-Pulse modes,
FREQ.MODULATION	Arc controls changes the frequ-
(Low)-10.0 to	ency modulation. The freque-
(High)+10.0	-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.

START OPTIONS

PREFLOW TIME	DESCRIPTION
0 - 25.0 seconds	Adjusts the time that shielding
	gas flows after	the trigger		is
	pulled and prior to feeding wire.
RUN-IN WFS:	Run-in sets	the wire		feed
Off, 30 to150 in/min.
	speed from the time the trigger
	is pulled until an arc is estab-
	lished.
Start Procedure	The Start Procedure		control s
	the WFS. Trim a t a specified
	time at t he beginning		of t he
	weld. During the start time, the
	machine will ramp up or down
	from the Start Procedure to the
	preset Welding Procedure.

END OPTIONS

Spot Timer	Adjust the time welding will
0 to 120.0 Seconds	continue even if the trigger
	is still pulled. This option
	has no effect in 4-Step
	Trigger Mode.
Postflow Time:	Adjusts the time that shielding
0 to 25.0 seconds	gas flows after the welding out-
	put turns off.
Burnback: 0 to .25	The	burnback		time		is t he
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 P rocedure			controls			the
	WFS and Trim for a				specified
	time	at	the end	of t he wel d
	after	the trigger		is	released.
	During		the Crater		time,		t he
	machine will ramp up or down
	from	the Weld Procedure					to
	the Crater Procedure.
