In most cases, cleaned electrodes can be reused. However, it is essential to inspect the electrodes after cleaning to ensure that they are in good condition and free from any damage or excessive wear. If the electrodes show signs of significant wear, such as a worn or damaged tip, it is recommended to replace them. Regularly cleaning and inspecting the electrodes will help maximize their lifespan and ensure consistent and high-quality welds. If in doubt, consult the manufacturer's guidelines or seek advice from a welding professional.
