The following functions allow setting programming limits that
are unique to a given weld schedule. The new limits override the
limits programmed in the setup parameters, and apply only to
the weld schedule where they appear. They also take priority
over any other limits established.
>?D5*
Refer to “Parameter Descriptions” on page 6-2 for detailed descriptions
of these limit settings as programmed in the setup parameters.
76 SEC. CURR LIMITS: HI=nnnn0 LOW=nnnn0
77 ISOLATION CONTACTOR DELAY=nn SEC
90 TRANSFORMER TURNS RATIO nnn:1 (nnn=1-256)
96 POWER FACTOR LIMIT: HI=nn% LOW=nn%
97 C-FACTOR LIMIT: HI=nnn LO=nnn
19 KVAT LIMIT: HI=nnnn LO=nnnn
This function defines the acceptable range of KVAT. This is
the measure of actual energy applied to the weld.
84 WINDOW: HI=+ nn% LO= -nn% C-FACTOR=nnn
This function permits defining a current limit window with
high and low limit values. The action of this function is based
on the firing mode used by the weld function: %I or
Automatic Current Compensation. For further details of this
feature, refer to “Dynamic Current Windows” on page 5-4.

39 TEST FIRE nn% CURRENT (nn = 20-99)
When it executes Function #39, the control will fire one cycle
of weld current at the percentage of maximum available
current programmed.
The control monitors and records both the actual current and
the power factor during that cycle.
The control uses this test fire to determine the initial
secondary resistance of the weld, and whether the electrodes
tips were touching, based on current draw. Other functions
(described below) also use the data generated by the test fire.
91 FAULT IF TIPS TOUCHING
This function generates a fault condition if the test fire from
Function #30 (above) determined that the welding electrodes
were touching.
These conditions must be true when using this function:
