4.2V Portable Spot Welder Kit Automatic Welding Tools Adjustable Mini Spot Welding Machine 0.12 Nickel Strip 18650 Batte

Description The welding machine precisely controls the output current of the MOS tube through the single chip microcomputer A high temperature of more than 2000 degrees is generated at the welding point to make the nickel sheet welded firmly The welding machine itself has functions such as over current protection low voltage protection over voltage protection and over temperature protection Intelligent output current It can be used safely even if the soldering pen s short circuited it will not be damaged Principle As shown in the figure a high speed protection system is built in the microcontroller When the welding current is too large the ultra high speed comparator will instantly turn off the output as shown by the red arrow to achieve the purpose of protecting the welding machine Under normal circumstances this function module will not triggerOnce the protection is triggered lift the pen to automatically release the protectionSpecification Product Name Handheld Desktop Spot WelderMaterial hard aluminum alloyWeight about 480gColor black shell brass soldering penSize 110mm x 85mm x 30mmSuitable for 0 1mm 0 15mm nickel platingFeatures 1 automatic trigger detachable soldering pen TYPE C charging short circuit protectionDesign Sturdy appearance light splash resistance firm connection dispersion brazing pen life span of 50 000 cycles 2 0 1 smm nickel strip welding force steel shell 18650 battery assembly For large monomers the aluminum electro
