Operating Process Monitor
NOTE: Once the unit is powered up, press the knob once to enter the Process Monitor screen.
To setup the tolerances effectively, destructive testing is needed to separate the good from the bad
welds.
To test the Process Monitor (PM):
First, perform several normal welds which should pass. If they fail, go to the Weld Details screen and
check which parameter(s) have failed (they will appear in red) and go to the Setup screen to open up
the tolerance or disable the parameter for checking. One of the conditions below should fail the PM:
1. Stud welded out of perpendicular position to the workpiece.
2. Damaged timing tip on stud.
3. Workpiece contamination.
4. Poor quality weld ground connections.
The unit can be configured to lock the user out if there is a failure. Go to Setup screen and turn on
STOP ON BAD WLD
.
After a suspect weld is detected, a popup screen will display
FAILED WELD
. Click on knob to
acknowledge message before proceeding with another weld.
There is also a resettable good weld counter and a bad weld count within the Setup screen.
