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-i n set s the wir e feed
	speed from the time the trigger
	is pulled until an arc is estab-
	lished.
Start Procedure	The Start Procedure controls

	ARC CONTROL
ARC		DESCRIPTION
FOCUS
-10.0 (SOFT to		Arc Focus adjusts the arc from
10.0 (STIFF)		a wide, soft arc good for out of
		position work to a narrow, stiff
		arc preferred for faster trav el
		speeds. The pulse frequency is
		lower with a soft arc and higher
		with a stiff arc.

	END OPTIONS
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		Th e burnba ck tim e 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 P rocedure controls the
		WFS and Trim for a specified
		time at the end of the weld
		after the trigger is released.
		Dur ing the Crat er tim e, t he
		machine will ramp up or down
