FAULT IF TIPS TOUCHING
This function generates a fault condition if the test fire from
Function #39 (above) determined that the welding electrodes were
touching.
These conditions must be true when using this function:
•
Function #39 (TEST FIRE nn% CURRENT) MUST appear in
the weld sequence.
•
Function #91 must appear after the test fire function (#39) in
the weld sequence.
•
Function #92 (FAULT IF TIPS NOT TOUCHING) cannot
appear in the weld sequence.
When it executes Function #39, the control monitors the actual
weld current. If the control detected
more than
10 A. primary
current, it assumes that the electrode tips
were
touching and
generates a TIPS TOUCHING fault.
Caution:
If Function #39 appears more than once in a sequence,
the control uses the data from the most recently-
executed test fire.
92
FAULT IF TIPS NOT TOUCHING
This function can generate a fault condition if the control
determines that the welding electrodes are NOT touching.
These conditions MUST be true when using this function:
•
Function #39 (TEST FIRE nn% CURRENT) must appear in
the weld sequence.
•
Function #92 must appear after the test fire function (#39) in
the weld sequence.
•
Function #91 (FAULT IF TIPS TOUCHING) cannot appear in
the weld sequence.
When Function #39 executes, the actual weld current during that
one cycle weld is monitored. If
less than
10 A. primary current is
detected, the control assumes that the electrode tips were NOT
touching. It generates a TIPS NOT TOUCHING fault.
