Automatic Rotating Cleaning: Keep the solder tip at 300°C before cleaning. Simply turn on the power switch, and the rotating copper brush will efficiently remove oxides from the solder tip. Caution: Do not exceed 400°C to avoid rapid re-oxidation after cleaning. Dual Cleaning Mode: For stubborn oxides that the automatic cleaner cannot remove, please use the included copper brush for manual cleaning. Please note: Manual cleaning may leave slight scratches on the solder tip surface. Gentle and Effective Solder Tip Protection: Safely removes oxides without damaging the solder tip. When used with chemical cleaning paste, it restores the solder tip's shine and allows for re-tinning, resulting in optimal soldering performance. Compact Design: Lightweight (0.8kg), saves space and is easy to store. Comes with a 1-meter power cord for flexible placement; power consumption is only 5W.
