TYPE 1

This product is very useful in daily life, with an battery, it will become an energy storage spot welding machine for welding nickel pieces such as lithium batteries and nickel-chromium batteries practical, easy to operate and use, wide application range, has a long service life. Come on and try it.

Features:
There is a window on the back of the drive part, you can add copper or tin by yourself.
The external pads for the LED and the on-board buttons are added to facilitate the connection of the LEDs and buttons on the board to other places.
The upper and lower MOS design is bold and tinned to make the internal resistance smaller and the current stronger.
Using 25V low internal resistance and high frequency capacitors makes the power supplies more stable.
This circuit with a 12-V battery will become an energy storage spot welding machine for welding nickel pieces such as lithium batteries and nickel-chromium batteries. According to different configurations, the thickness can be about 0.1mm-0.15mm

Specifications:
Material: PCB
Suitable for: 18650/26650/32650 lipo battery
System voltage: 12-V-14.6V
Working current: 90-150A
Suggested battery: (not included)
20-45ah Lead-acid battery with fine performance and small internal resistance
3.5-5.5ah 45C 3S aeromodel lithium battery pack

Package weight: 110g / 3.9ounce

Note:
If the battery is pretty  and the internal resistance is very low, and then there may be large current overload.
If you are not sure about your battery, it's better to extend the wire by around 1 meter with 2.5² or 4² wire, then it will reduce the risk of power tube burnt.

Packing list:
1 * Main Circuit Board
2 * Input Wire
2 * Output Wire(with Welding Pen)
1 * Welding-Components Kit


TYPE 4

This is a kind of fine quality welding pen set, suitable for welding 18650/26650/32650 battery. The welding current approx. 90-130A, which is more than enough to welding common 0.1mm-0.12mm nickel plate. Upgraded to automatic triggered design, do not need to press button for long time anymore, completely frees your hands. You can have a try.

Features:
Lightweight and portable, stable and reliable, wear resistant and can provides long service time.
Through the MOS tube output, this energy will be concentrated at the end of the welding pen, and it will be heated by short circuit.
Fuse the nickel sheet firmly with the battery.
And it is precisely controlled by the single-chip microcomputer program without trigger switch.

Type 5

Features:
There is a window on the back of the drive part, you can add copper or tin by yourself.
The external pads for the LED and the on-board buttons are added to facilitate the connection between the LEDs & buttons on the board and other places.
The upper and lower MOS design is bold and tinned to make the internal resistance smaller and the current stronger.
Using 25V low internal resistance and high frequency capacitors make the power supplies more stable.
Switch Function: press the switch for 1.5 seconds (green light flashes, low power spot welding pulse is output every 3 seconds); press the switch for 1.5 seconds (the blue light flashes and the medium power spot welding pulse is output every 3 seconds); press the switch for 1.5 seconds (red light flashes, high power spot welding pulse is output every 3 seconds); press the switch for 1.5 seconds to turn off the machine.
This automatic trigger spot welding machine can weld nickel plating (0.1mm~0.15mm) of 12V lithium batteries and nickel-chromium batteries with a 90A~150A welding current.
The following battery pack can be used as working power supply: the battery pack that can start the car can basically meet the power supply demand of this circuit, such as 12V car starting power supply, aeromodelling 3S high-rate battery pack, 3-string high-rate lithium battery pack, 12V 20A lead-acid battery with good performance, etc.

Specifications:
Material: PCB
Color: Black
System Voltage: 12V~14.6V
Working Current: 90A~150A
Suggested Battery (NOT included): 
20~45ah lead-acid battery with good performance and low internal resistance
3.5~5.5ah 45C 3S aeromodelling lithium battery pack
30~35ah capacity 18650 battery pack

Package Size: Approx. 190*110*30mm / 7.48*4.33*1.18in
Package Weight: Approx. 200g / 7.05oz

Note:
Spot welding is based on local rapid heating and cooling with large current, which requires sufficient current supply. Generally, the welding current of 0.1mm~0.15mm nickel plated sheet is about 90A~150A, so the working power supply of circuit board must be greater than or equal to 150A.
