Maintenance Tips

• Inspect power cords, welding leads, and connectors before each use for wear, cracks, or loose connections.
• Keep cooling vents and internal airflow passages free of dust, metal particles, and debris to prevent overheating.
• Clean exterior surfaces regularly with a dry cloth or low-pressure compressed air.
• Check cooling fans for proper operation and remove any buildup that may restrict airflow.
• Inspect output terminals and grounding connections for corrosion, overheating, or damage.
• Verify welding controls, displays, and voltage settings function correctly before operation.
• Store the welder in a clean, dry environment away from moisture, excessive dust, and extreme temperatures.
• Follow recommended service intervals and address unusual noises, error codes, or performance changes promptly to maintain reliable welding performance.
