1S Mini Spot Welding Machine with Micro USB Interface Quick-Release Pens for DIY 18650 Lithium Battery Nickel Belt

This spot welding machine is mainly used for welding nickel sheet of cylindrical battery, NI-MH battery, nickel cadmium battery like 18650 and etc.. With output power and remaining power indication, there are two output modes: 1.5s timing trigger output and automatic detect welding pen output. Built-in high-rate polymer power cell, the maximum output current is up to 639A, and it can continuously weld thousands of points after being fully charged. You can have a try.

Features:
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..
With output power and remaining power indication, there are two output modes: 1.5s timing trigger output and automatic detect welding pen output. 
4 gears of output power adjustable, 1gear(lowest) and 4gear(highest).
Full intelligent microcomputer control: battery over discharge and battery over charge are protected, welding pulse control, support charge and use at the same time.
Built-in high-rate polymer power cell, the maximum output current is up to 639A, and it can continuously weld thousands of points after being fully charged.
Has four dual-color indicator lights, green light for indicating the remaining quantity of electricity, red light for indicating the output power.
Charging indicator light: red for charging, green for fully charged.
