7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your welding machine.
- Cleaning: Periodically clean the machine's exterior and ventilation openings to prevent dust and debris buildup. Use compressed air to clear internal components if necessary, ensuring the machine is unplugged.
- Consumables: Inspect and replace MIG torch tips, nozzles, and contact tips regularly. Ensure the welding wire feed rollers are clean and free from debris.
- Cable Inspection: Check all cables (power, ground, torch) for any signs of damage, cuts, or fraying. Replace damaged cables immediately.
- Storage: Store the welder in a dry, clean environment when not in use.

8. Troubleshooting
If you encounter issues with your RBM1650PRO welder, refer to the following common troubleshooting steps:
- No Power: Check the power cable connection, ensure the power switch is ON, and verify the circuit breaker.
- No Arc: Ensure the ground clamp is securely attached to the workpiece, the electrode/torch is correctly installed, and the welding parameters are set appropriately for the material and thickness.
- Poor Weld Quality: Adjust welding current/voltage, check wire feed speed, ensure proper gas flow (if applicable), and clean the workpiece surface.
- Overheating: If the overload indicator lights up, allow the machine to cool down. Ensure proper ventilation and avoid exceeding the duty cycle.
