When is Maintenance Required?
Maintenance requirements will vary with environment and usage. Dirty work areas or high volume stud welding will require more frequent main- tenance.
There are three primary reasons for maintenance:
•Dirt - Dirt can enter the lifting mechanism and cause erratic lift and plunge operations. Typically , cleaning is all that is required.
•Wear - Components do wear out over time. Typically, items such as plastic bearings or cables wear out and need to be replaced.
•Improper Use - Components can arc out by inadvertently placing them against grounded materials during a weld sequence. Also, by us- ing the gun as a hammer to test welds will damage parts and require maintenance.
Maintenance Steps
Proper Maintenance Procedures:
•Disassemble the gun.
•Inspect all parts for wear or damage.
•Replace worn or damaged components.
•Clean all components.
•Reassemble components.
•Adjust settings and test.
