LIMITS
Limits allow the welder to adjust the welding procedure
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.
Machine limits are:
