The weld processor also monitors the power delivered to a weld.
This value, known as the KVAT, represents the actual power
delivered to a weld. It is the computed by the equation:
Where
V
p
is average primary voltage
I
p
is average primary current
Cycles is number of cycles weld current.
The MedWeld 3005 provides a function to define the range of
acceptable KVAT values.
19 KVAT LIMIT HIGH=0000 LOW=0000
This defines the range of KVAT that is within acceptance. The
processor monitors actual KVAT, and will generate a fault
condition if the actual KVAT exceeds the range specified in
the weld sequence.
The High Current/KVAT Limit Fault and Low Current/KVAT
Limit Fault setup parameters define the severity of the fault
condition generated by the weld processor when the limits
defined in Function #19 are exceeded.

You can define a window of acceptable values for current. To
define this window, use the setup parameters: High Current
Limit and Low Current Limit.
These parameters, along with the Nominal C-Factor parameter,
define the acceptable range of current to expect. You can also
override the values in the setup parameters by inserting into the
weld schedule Function #84 (WINDOW: HI=+00% LO=00% C-
FACTOR=000).
