Features:

*1. Adopts 5pcs MOS tubes, and the max current is up to 2390A.

*2. High power output design, 99 gears of output power adjustable, more accurate welding, and it can continuously welding thousands of points on nickle/nickelplate sheet.

*3. The welding is based on the principle of high-current and high-temperature rapidly melting the part of nickel sheets and cooling.

*4. Equipped with 2pcs copper bars, which are greatly increase the overcurrent capacity.

*5. The welding spots are accurate and beautiful, support welding 0.05-0.3mm nickel sheet, iron sheet, stainless steel sheet.

*6. This spots welding machine can be used to spots welding cylindrical lithium batteries and nickel-metal hydride batteries like 14650/17490/18650/21700/26650/32650 and etc..
