This is a kind of fine quality spot-welding machine, which is made of aluminum alloy material, with anodic oxidation surface, wear resistant and beautiful. Mainly used in the welding of nickel sheet of cylindrical battery, NI-MH battery, nickel cadmium battery like 18650 and etc.. It can welding hundreds of welding points on commonly used nickel-plated sheets within 0.1mm-0.15mm. You can have a try. Features: The welding spots are accurate and beautiful, support welding 0.1-0.15mm nickle sheet. Mainly used in the welding of nickel sheet of cylindrical battery, NI-MH battery, nickel cadmium battery like 18650 and etc.. Output gears indicator light(red), the number of indicator light corresponding the output gears. Equipped with electricity indicator light(blue), different numbers to shows different electric quantity, 1 lights (5-25%, flash5%), 2 lights(25-50%), 3 lights(50-75%), 4 lights(75-100%). 6 gears of output power adjustable, welding more accurate(1gear-lowest, 6gear-highest). Automatic mode and manual mode adjustable, and there are two yellow indicator lights, the right light turn on means under manual mode, the left light turn on means under automatic mode Intelligent micro-computer control, over-discharge and overcharge are protected, accurate pulse control, support recharge while use. Gold-plate terminal welding pen, with fine conductivity and low contact resistance, quickly detachment and easy carrying. 2mm thicken pure copper strip, supper-low internal resistance to increase over-current capability. Built-in high-rate polymer power cell, the maximum output current is more than 650A, and it can continuously weld thousands of points after being fullyrecharged. Built-in temperature control probe, with temperature-control-protection function, it will automatic cut off power when the temperature is higher than 60.
