• Post Delay (Default Setting: 0)
Once weld current has ended, the weld monitor waits for a period of time to see if weld current
begins again. This amount of 'waiting' time can be specified in halfcycles using the Post Delay
setting. If weld current does not begin again after the Post Delay, the weld monitor considers the
weld finished. If weld current resumes within the Post Delay time period, the weld monitor
continues data collection. This is particularly useful for pulsed or seam welding applications.
For example, if the weld process included a pulsed weld (5 cycles on, 2 cycles off, 5 cycles on) the
Post Delay would need to be increased to at least 4 halfcycles in order to bridge the 2 cycle gap
between the pulses. If the Post Delay were set to 0, then the weld monitor would incorrectly
consider this process as two separate welds.
Note:
The Post Delay should be set to the same value used during mastering.
• Masters Enabled (Default Setting: Yes)
Yes: Each weld is compared to a master, if one exists. Depending on tolerance settings, each weld
is accepted or rejected based on this comparison.
No: Masters are disabled, and the WeldWise™ 2400 monitors without comparing welds to
masters.
Note: All welds will be rejected for all parameters when masters are disabled.
• Halfcycle Data Mode (Default Setting: None)
All:
All halfcycle data records (record type 0) will be recorded and stored in the database. If a
halfcycle is stored in the database, then the associated weld record must be stored also. If
Halfcycle Data Mode is set to All, Weld Data Mode is also automatically set to All.
Failed: If a weld is rejected, halfcycle data is recorded only for those halfcycles that were out of
tolerances (failed). If Halfcycle Data Mode is set to Failed, Weld Data Mode cannot be
set to None.
Note: When viewing the halfcycle data graph, halfcycles that did NOT fail are filled in
with data points from the master and displayed along with the “failed” halfcycles.
None: No halfcycle data records will be recorded.
For most high-volume applications, storing all of the halfcycle data records is not practical during
normal production. A 20-cycle weld will produce 60 halfcycle data records, including 10
halfcycles of pre-weld data, and 10 halfcycles of post-weld data. For this reason, the default
settings have Halfcycle Data Mode in None.
