1S Mini Spot Welder Welding Machine DIY 18650 Lithium Battery Nickel Belt Spot Welding Portable Household Fiber Welding

QA Q What is the difference between the Upgrade 1S and the previous 1 A 1S has added the function of adding your idle automatic discharge which can automatically discharge to 50 in 5 days and extend the battery life 1S also optimizes the circuit layout and structure with better performance In addition type C charging port version is added to 1S Q What is the difference between type C and micro USB A Type C version uses type C charging port supports positive and negative plugging and distributes a type C charging line In addition the type C circuit uses the gold deposition process Q Does type C support fast charging A Considering that fast charging may affect battery life it only takes about 2 hours to charge from 50 to 100 so fast charging is not supported Feature Aluminum alloy shell material fire proof and anti fall Surface anodizing technology anti abrasive and safe to use Portable Spot Welding Machine is mainly used in the welding of nickel sheet of cylindrical battery like 18650 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 With output power and remaining power indication there are two output modes timing trigger output and automatic trigger output At the same time can sett 4 output power Has four dual color indicator lights Green light for indicating the power red light for indicating the welding power Charging indicator light red fo
