Portable Mini High Power DIY Nickel Strip Connection 18650 Battery Welding Machine Spot Welder 3.7-4.2V 300A

Product introduction: 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 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. parameters: Voltage: 3.7-4.2V Current: 300A Battery capacity: 5000mAh Size: Approx. 180x85x25MM Weight : Approx. 287G How to use : 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 Fix the welding pen and soldering tape to use Warning: Do not hold the switch for a long time Please press down hard when spot welding to prevent poor contact Do not short circuit, you can use electrical tape or heat shrink film winding

• 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 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.
• Voltage: 3.7-4.2V
