ARC CONTROL

PULSE		DESCRIPTION
FREQUENCY:
(Low)-10.0 to	For Pulse modes, Arc Control
(High)+10.0	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.
START OPTIONS
PREFLOW TIME		DESCRIPTION
0 to 10 seconds		Adjusts the time the 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.

EFFECT / RANGE	FUNCTION
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 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.
Spot Timer:	Adjusts the time welding will
0 to 10 Seconds	continue even if tigger is still
	pulled. This option has no
	effect in 4-Step Trigger Mode.
