I. Daily Preventive Maintenance
1. Daily Inspection
Check the welding gun nozzle for blockage and clean spatter (to prevent abnormal shielding gas flow).
Test the robot's trajectory to observe any stalling or deviation (immediately shut down if abnormal).
Confirm the cooling system water level and temperature (30-50°C is a safe range).
2. Cleaning
Remove welding slag and metal powder from the table daily, and use a vacuum cleaner to remove debris inside. Regularly clean the positioning holes with compressed air to prevent blockage that affects accuracy.
II. Periodic Maintenance Schedule
1. Replacement of Consumable Parts
Replace the contact tip every 500 meters of wire welded, and replace the wire feed roll if wear exceeds 0.2mm.
Replace the robot rail grease during quarterly maintenance (Molykote is recommended). EM-50L
2. Precision Calibration
Calibrate positioning accuracy using a laser interferometer every three months (error ≤ 0.05mm).
Check the output voltage stability of the welding power supply to prevent arc anomalies.
III. Procedure and Safety Control
1. Procedure Management
Back up welding parameters and robot path programs weekly to prevent data loss. Unauthorized modification of welding procedures is prohibited. Back up and test any changes before making them.
2. Safety Protection
Inspect cable insulation before operation. Replace any damaged insulation immediately (to prevent leakage risk). Ensure the emergency stop button is functioning properly and test its response speed monthly.
IV. Fast Fault Response
1. Establish a Fault Log
Record fault symptoms, corrective measures, and time to accumulate maintenance experience. Prioritize simple issues (e.g., check wire level if wire feed is interrupted).
2. Professional Support
Contact a technician for calibration if positioning deviation exceeds 0.1mm; avoid making adjustments yourself.
