Description:
In the 18650 battery pack assembly process, the spot welder is an indispensable important tool, but the ordinary spot welder on the market is bulky and has a relatively high weight. The common spot welder generally adopts a transformer structure and generates a large amount of heat The current controlled is not accurate, causing the solder joint to be black or weak.
This product is a compact spot welding machine control board, with a large rate polymer lithium battery, discharge up to 150a, enough for general welding. The product has only one switch, each with three output powers, green - low power blue - medium power Red - high power. 2 seconds output, no need for manual or foot trigger, really free hands
For safety and beauty, we have designed a version with a shell, using a high-current crystal plug, it will not heat up for a long time, use USB data cable to charge, do not need a bulky power supply or charger, you Can use the mobile phone charger to charge directly.
The product is smaller than the average charging treasure and can be used on the plane.
At present, the product supports direct spot welding of nickel tape below 0.25mm, and the adhesion is strong. It is enough for buyers who are not for industrial use.
Used for battery assembly spot welding of 18650, 26650, 32650 battery assembly.
This circuit with 12V battery will become a storage spot welding machine for lithium battery, nickel-chromium battery and other nickel sheet welding, according to different configurations can be welded thickness of 0.1MM-0.15mm or so, we have customers through replacement The thick wire (10 square meters) can barely weld 0.2mm thickness. After all, this device is for electronic enthusiasts, the frequency of use is not very high, so you can also use 0.1-0.15 solder 2 to replace thicker nickel.

Specification:
Weight : 287G
Size :180x85x25MM
Voltage: 12-16V
Current: 150A

Operation method:
1. Short press the switch to turn on (green light flashes, output low power spot welding pulse every 3 seconds), press switch (blue light flash, output medium power spot welding pulse every 3 seconds), press switch (red light flash, Output high-power spot welding pulse every 3 seconds) Press the switch to shut down.
2. Fix the welding pen and soldering tape to use.

Note:
1. Do not hold the switch for a long time.
2. Please press down hard when spot welding to prevent poor contact
3. Do not short circuit, you can use electrical tape or heat shrink film winding
