1、Powerful Function: Spot welder support 0.1 to 0.2mm thin plate spot welding, welding and welding joints more thorough.  2、Design Intention: Bilateral lead for easy spot welding, product identification to avoid misconnection, 99 gear power adjustment, digital tube real time gear display.  3、Multiple Protection: Real time voltage monitoring protection will display UE alarm code when the voltage is not in the range of 8 to 17V. Real time MOS tube temperature protection will show CE alarm code when the temperature exceeds 45 Celsius degrees.  4、High Efficiency: 10AwG welding wire, oxidized copper spot welding needle, to ensure over current capacity and durability, greatly improving the efficiency of spot welding.  5、Large Capacity:  Spot welder circuit board uses 5 MOS tubes, the maximum spot welding peak current can reach to 1500A. Solder more penetrationmore beautiful solder joint. 6、Wide Application: Spot welder circuit board for 18650 26650 32650 lipo battery welding and other cylindrical lithium batteries, nickel hydrogen batteries, nickel batteries, etc. can be welded firmly.
