1S Mini Spot Welding Machine with Type-C Interface Quick-Release Pens for DIY 18650 Lithium Battery Nickel Sheet

Features:
Made of aluminum alloy material, with anodic oxidation surface, wear resistant and beautiful.
It can welding hundreds of welding points on commonly used nickel-plated sheets within 0.1mm-0.12mm.
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 light(5-25%, flash＜5%), 2 lights(25-50%), 3 lights(50-75%), 4 lights(75-100%).
4 gears of output power adjustable, welding more accurate(1gear-lowest, 4gear-highest).
Automatic mode and 1.5s timing mode adjustable, automatic mode-automatic detect welding pen, timing mode-1.5s timging output.
Intelligent micro computer control, overdischarge and overcharge are protected, accurate pulse control, supoort charge while use.
Gold-plate terminal welding pen, with fine conductivity and low contact resistance, quickly detachment and easy carring.
2mm thicken pure copper strip, supperlow internal resistance to increase overcurrent capability.
Built-in high-rate polymer power cell, the maximum output current is more than 639A, and it can continuously weld thousands of points after being fully charged.
