• Load Station
• Two Part Check Stations: before and after the weld operations
• Two Weld Stations
• Good Part Unload Station

 The PLC tracks part status through all stations. If a part is determined to  be bad, no more work is performed to the part. It returns to the Load  Station where a message appears on the MMI screen to alert the Operator,  who removes and separates the bad part. Only good parts are unloaded at  the Unload Station. All cell motions are sensed and all possible fault  conditions are displayed on the MMI.

 Guarding completely surrounds the cell, except for a light curtain at the  manual Load Station. Opening a guard door will immediately inhibit all cell  motion, similar to an Emergency Stop condition.
