Select
UPPER LIMIT: none
or
LOWER
LIMIT: none
, using Table 8-1 as a guide.
Use the numeric keypad to enter limit
values.
This example shows that the
UPPER
LIMIT
has been set to none and the
LOWER LIMIT
has been programmed for
0.750 V. Use the Basic Weld Monitor, as
previously described in this chapter, to gather measurements that can be used in setting the Upper
Energy Limit or the Lower Energy Limit.

You are now back in the Energy Limit

RUN
State. If the actual
measured value goes above the Upper
Limit or below the Lower Limit, the
Power Supply automatically terminates
welding and records the actual period
during which the weld energy was on.
This example shows that the weld energy
dropped below the 0.750 V Lower Limit
9.7 ms after the start of the weld.
