1. 6 square pen can spot weld 0.05-0.2 mm nickel plating sheet, 10 square pen can spot weld 0.05-0.3 mm nickel plating sheet 2. High-power output design, 99 adjustable output power, welding more accurate, can be in nickel/nickel plate continuous welding thousands of points 3. Using 5 MOS transistors, the current can reach 2390A 4. Welding is the use of high current and high temperature rapid melting of nickel foil parts and cooling principle 5. Equipped with two copper bars, greatly increased the ability to over-current 6. Welding spot accurate and beautiful, support welding 0.05-0.3 mm nickel sheet, iron sheet, stainless steel sheet 7. The spot welder can be used for spot welding of lithium cylindrical battery and ni-mh battery, such as 14650/17490/18650/21700/26650/32650, etc. 8. Display: digital tube display 9.
