1. Construction: The helping hand solders feature a bottom plate treated with quality plastic spraying to ensure durability and a long service life. The solid columns undergo electrochemical treatment, enhancing their performance for comprehensive use. 2. Insulated electrified columns: The soldering helping hands are equipped with insulated electrified columns that clamp securely during online debugging or maintenance. This design minimizes the risk of accidental contact with solder joints, ensuring user safety during operation. 3. Precision work: With a compatible board thickness range of 0.2–2 mm, it is versatile for various applications. 4. Caution: The solder helping hands are sensitive to temperatures. Avoid directing hot air directly at the pillars, as the iron boron magnets may lose magnetism under extreme conditions. Proper care maintains tool integrity.
