Description
This is the amount of delay the power source should use when applying
limits at the beginning of this weld. The Start delay is the amount of time (in
seconds) that the power source should wait, directly after the start of a weld,
before it begins to apply the limits entered for this Weld Profile. This option
is necessary because the start of a weld is often unpredictable and may fall
out of limits easily. (The Start delay must be within the range of 0.1 seconds
to 10.0 seconds.)
NOTE | The combined Start delay and End delay times must be 0.7
seconds or greater if the Production Monitoring firmware on the power
source is at revision 4. If the total is less than 0.7, Power Wave® Manager
automatically adjusts the Start delay value so the total equals 0.7 seconds.
If the Production Monitoring firmware revision is 5 or greater, the
combined Start delay and End delay times must be 0.4 or greater. If the
total is less than 0.4, Power Wave® Manager automatically adjusts the
Start delay value accordingly.
This is the amount of delay the power source should use when applying
limits at the end of this weld. The End delay is the amount of time (in
seconds) directly before the end of a weld that the power source should
stop applying the limits entered for this Weld Profile. This option is
necessary because, at the end of a weld, the set points for the Welding
Power Source are often different than the rest of the weld (e.g., if the power
source is in a burn-back state). The End delay must be within the range of
0.1 seconds to 10.0 seconds.
Place a check mark next to this option to tell Production Monitoring™ or
CheckPoint™ that it should not record welds where the duration of the weld
is shorter than the combined Start delay and End delay times.
If this option is unchecked, welds that are greater than 0.4 seconds but less
than the Start plus End delay time will be recorded but will be marked as a
Short Weld.
Every quarter of a second, the Welding Power Source compares the
performance of the current weld against the trained weld for the selected
Weld Profile. When the weld is complete, the power source averages those
measurements together for an overall WeldScore™.
The Minimum WeldScore field allows you to enable the action you selected
for WeldScore™ on the Out-of-limit actions tab (page 10.5). If the overall
WeldScore™ for the weld falls below the value you enter here, the system
performs the action you selected in the Action on WeldScore limit drop-down
on the Out-of-limit actions tab.
Even if you do not have the alerts enabled, the power source still calculates
WeldScore™ on machines that support this value (if a training model exists
