LIMITS

Limits allow the welder to adjust the welding proce- dure only within a defined range.

Each user memory may have a different set of limits. For example, memory 1 can be set to limit the WFS to 200 through 300 in/min, and memory 2 can be set to limit the WFS to 275 through 310 in/min, while memo- ry 3 may not have any WFS limits.

Parameters are always constrained by machine limits. When memory limits are enabled, the parameter will flash whenever an attempt is made to exceed the memory limit value. The parameter will not flash if an attempt is made to exceed the machine limit.

The system machine limits are:

Parameter	Range		Units
Wire Feed Speed	Weld mode and wire		in/min
	feeder dependent.
Voltage	Weld mode dependent		Volts
Trim	0.50 to 1.50		--
Arc Control	-10.0 to 10.0		Weld mode dependent
Preflow	0.0 to 2.5		Seconds
Start Time	0.0 to 10.0		Seconds
Run-In WFS	Off, 50 to 150		in/min
Crater Time	0.0 to 10.0		Seconds
Burnback Time	0.00 to 0.25		Seconds
Postflow Time	0.0 to 10.0		Seconds
Limits may be set for:
• Wire Feed Speed/Amperage		• Start Time
• Voltage/Trim		• Burnback Time
• Arc Control		• Crater Wire Feed Speed
• Preflow Time		• Crater Voltage/Trim
• Run-In Speed		• Crater Time
• Start Wire Feed Speed		• Postflow Time
• Start Voltage/Trim

Weld modes cannot be selected through the Limits Setup memu, and must be chosen and saved to mem- ory before entering the Limits Setup Menu.
