Setting Limits
From within any weld mode, you can set the main parameter (indicated by the name of the weld mode) and
Hold Time and several other parameters. The other parameters you can set include Suspect Limits and
Reject Limits. You can reduce the amount of scrap from unacceptable parts by identifying those parts that
are slightly out of range using Suspect and/or Reject Limits. Upon manual inspection, you might find that
these parts are acceptable. You can set the Suspect and Reject Limits on the Power Supply to identify (by
counter, printed output, or alarm) all parts that fall into limit categories.
For example, consider a weld cycle in Time Weld Mode where you have set the time to 0.280 second. You
have determined (by laboratory testing, trial and error, or some other means) that you get an acceptable
weld when 100 to 110 Joules of energy have been transmitted to the part. These are the limits that you
should then set on the Power Supply as Suspect Limits. You have also determined that the part is a “reject”
if it received fewer than 95 Joules or more than 115 Joules. This is illustrated in the following bar graph:
You can set Suspect and Reject Limits for meaningful parameters in each weld mode.
