• Innovative Dual-Tip Design: Features both a micro needle tip for precision welding on thin materials and a macro cone tip for deep penetration on thick materials, doubling versatility and durability in one tool.
• Precision Micro Welding: The micro needle tip achieves ultra-thin material welding with high accuracy (+0.05mm), preventing piercing and ensuring clean, reliable connections.
• Efficient Macro Welding: The macro cone tip delivers balanced heat distribution for deep welding on thicker materials, reducing the heat-affected zone by 30% to prevent weak joints.
• Premium Material & Long Life: Constructed from high-conductivity aluminum oxide copper, it offers exceptional electrical performance and a extended service life of over 5000 cycles.
• 5000mAh Large Capacity: The internal structure of the H5 spot welder has been completely upgraded, with a spot welding thickness of 0.1-0.3mm, and can even spot weld pure nickel with a thickness of 0.2mm. Built-in 5000mAh battery, can spot weld for longer, but it is not recommended to operate for long periods of time.
