ARC CONTROL
EFFECT / RANGE	DESCRIPTION
PINCH EFFECT	Adjust the short circuit current
(-10.0 to +10.0)	to create a soft arc, or a force-
	ful, digging arc.

START OPTIONS

The start Options available in these synergic CV weld modes, their adjustment range and function are as follows:

EFFECT / RANGE	DESCRIPTION
Preflow Time	Adjusts the time the gas flows
0 - 25.0 seconds	after the trigger is pulled and
	prior to feeding.
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 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.

END OPTIONS
EFFECT / RANGE		DESCRIPTION
Postflow Time		Adjusts the time that shielding
0 to 25.0 seconds		gas flows after the welding out-
		put turns off.
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.
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 120.0 Seconds		continue even if tigger is still
		pulled. This option has no
		effect in 4-Step Trigger Mode.
