Manual part number: BE 1227

The important thing to note is that normally, the stud begins to drop at Front Panel
Time
– Drop Time. But if the Drop Time exceeds the Front Panel Time, the stud would
need to begin to drop prior to the start of the weld in order to make the Actual Weld
Time to be the same as the Front Panel Time. This is done by releasing the gun coil
during the pilot arc stage.
For example:
•
Front Panel Time = 20ms
•
Drop Time (F31) = 30ms
•
Plunge short circuit on
‐
time (F2) = 50ms
Since [20ms
– 30ms] < 0, the, the gun coil is released prior to starting the main current.
So the weld profile would look like this:
The resulting Actual Weld Time is 20ms. The stud would still take 30ms to drop, but
the main current and main arc would only be 20ms.
