Erroneous Low Time Limit Alarms

A low time limit can occur if the duration of the weld is less than the sum of the Start and End delays as set
by someone like a Weld Engineer during the setup of Weld Profiles (page X). When the TorchMate and
Touch Sensing options are used, the momentary touch the wire makes at the part or at the TorchMate
block is enough to cause a low time limit to be generated. If these become a nuisance, it is possible to turn
off Production Monitoring™/CheckPoint™ prior to running a Touch Sensing routine or running TorchMate
Adjust and then turn it back on again prior to making a weld.
Two programs are installed in the robot to turn Production Monitoring™/CheckPoint™ on or off: PM_OFF
and PM_ON. These are entered as a CALL instruction.
To avoid tampering with the original TorchMate Adjust program, it may be desirable to create a new
program titled TorchMate, for example, that begins with a line to turn off Production Monitoring™/
CheckPoint™, followed by the TorchMate Adjust instruction, and finishing with a line that turns Production
Monitoring™/CheckPoint™ on again, ready for the next weld.
Here is a sample program:
TORCHMATE
1: CALL PM_OFF
2: Torchmate Adjust
3: CALL PM_ON
END
Teach the two CALL instructions as shown above.
To teach the TorchMate Adjust instruction:
Procedure
1.
Press F1-INST.
2.
Cursor to line Macro and press Enter.
3. At new submenu, cursor to line TorchMate
Adjust and press Enter.
