Periodic and Preventive Maintenance
7.1.1
Maintenance Safety
Safety devices, especially covers, guards and ground cables should only be removed when
it is absolutely essential for the completion of maintenance work. If safety devices were
removed prior to starting maintenance work, be sure to re-install those devices after
finishing the maintenance work. The following installation and maintenance operations
must be performed prior to any disassembly of equipment:
WARNING
7.1.2
Periodic Maintenance
In order to maintain optimum operating conditions, it is important to perform various
maintenance and equipment inspections at periodic intervals. Please observe the following
recommendations in addition to those found in the General Information Instruction Set
under Periodic Maintenance.
7.1.2.1
Daily Maintenance:
• Check cut gap
• Check crash gap
• Perform Height Span Adjustment. See
• Check weld parameters energy, height, and time
• Inspect and clean tooling. Look for excessive wear, chips, or cracking. If found, tooling should be
rotated and the stack should be re-tuned. If the stack cannot be tuned, the tip should be
replaced. This will prevent poor sealing in production
• Measure the final weld thickness of sample parts to determine if they are within predetermined
tolerance range. Adjust proximity switch as necessary to achieve final weld thickness. See
Setting Weld Height Proximity Switch
7.1.2.2
Once a Month
• Inspect all cables and connections for any twisting or stress on the connectors
7.1.2.3
Every Three Months
• Service stack. Disassemble, clean interfaces and re-assemble tightening to the proper torque
7.1.2.4
On Every Tool Setup, Rotation and Replacement
• Inspect the clamping surfaces of the Tip, the Tip Nut and the Horn for fretting
• Vacuum and clean out any copper residue or dirt in the actuator
• For best performance, rotate tooling each 5,000 cycles
Note: Replace or maintain anvil first.
Anvil Replacement
• Power OFF
• Remove anvil nut, thrust washers, cooling cap, and anvil
• Remove air deflection plate and wipe off any excess copper dust, oil, etc
62
• All system components must be disconnected from the main electrical
supply
• Use LOTO (Lock Out Tag Out) lockable plug cover over line cord plug
during any maintenance
• Disconnect the air hose from the main air supply
