1S Mini Spot Welder Welding Machine DIY 18650 Lithium Battery Nickel Belt Portable Household Fiber Welding Machine Micro USB with Quick-Release Pens

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 plug-in, and distributes a type C charging line. In addition, the type C circuit uses the gold deposition process, which is more durable.

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.

- 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 set 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 for charging, green for fully charged.

- It will automatically shut-down after ten minutes of no use.

- Compact size and light weight, easy and convenient to carry.

- Adopt micro USB charging interface for easy charging.

- Full intelligent microcomputer control: battery over discharge protection, battery over charge protection, welding pulse control, support while charging

- Integrated welding pen uses gold-plate terminal, with fine conductivity and low contact resistance.

- Thicken pure copper strip and imported MOS tube can save energy and can provides long service time.
