RANMEI 99 gear spot welding unit control board 18 650 battery 0.05-0.3mm Nickel 12V

Features: brand new high quality Using 5 MOS tubes the maximum current can reach 2390A. High output power design 99-speed output power adjustable more precise welding can continuously weld thousands of nickel/nickel sheets. Welding uses the principle of high current and high temperature to rapidly melt and cool a part of the nickel sheet. Equipped with 2 copper bars which greatly increases the overcurrent capacity. The welding spot is accurate and beautiful and supports welding of 0.05-0.3mm nickel iron and stainless steel. This spot welder can be used for spot welding of cylindrical lithium batteries and NiMH batteries such as 14650/17490/18 650/21700/26650/32650.
