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 may limit the WFS to 200
through 300 in/min, and memory 2 may limit the WFS
to 275 through 310 in/min, while memory 3 may have
no WFS limits.
Parameters are constrained by machine limits, or by
setting memory limits. When memory limits are
enabled, the parameter will flash whenever an attempt
is made to exceed the memory limit value. The para-
meter will not flash if an attempt is made to exceed
the machine limit.
The system machine limits are:
Parameter Range
Wire Feed Speed Weld mode and wire
feeder dependent.
Voltage Weld mode dependent
Trim 0.50 to 1.50
UltimArc -10.0 to 10.0
Preflow 0.0 to 25.0
0.0 to 10.0
Start Time
Off, 30 to 150
Run-In WFS
Crater Time 0.0 to 10.0
Burnback Time 0.00 to 0.25
Postflow Time 0.0 to 25.0
Limits may be set for:
• Wire Feed Speed/Amperage
• Voltage/Trim
• Arc Control
Weld modes cannot be selected through the Limits
Setup menu, and must be chosen and saved to mem-
ory before entering the Limits Setup Menu.
To set limits, press the desired memory button 1-8
and hold for 5 seconds. Release the memory button
when the LED begins to blink rapidly and the user
interface displays "Memory X Set Limits" as shown
below.
